In short
Science-backed fertility support focused on separating egg quantity vs egg quality, addressing inflammation, and managing conditions like PCOS and endometriosis. Host also gives “non-negotiables” (sleep, stress regulation, nutrition, movement, toxin reduction) and discusses specific supplements/doses.
Guest backgrounds
No named guests; episode is led by Dr. Jolene Brighton (hormone doctor, nutrition scientist; secondary infertility; IVF experience).
Key claims
Fertility isn’t just age; AMH/ovarian reserve can look fine while ovulation, inflammation, insulin resistance, hormonal issues, or diagnoses (PCOS/endometriosis/autoimmune/thyroid) still block conception. Chronic inflammation can disrupt hormone signaling, ovulation, insulin resistance, embryo environment, and implantation. Anti-inflammatory meds may not be appropriate; progesterone is framed as immune “tolerance” rather than suppression.
Notable examples
Age 35+ egg quality decline estimates (35% lower quality by 35; ~50% by 40). CoQ10 200–600 mg/day for 3–4 months (egg maturation/embryo quality). PCOS = insulin resistance, androgen excess, irregular cycles; endometriosis = systemic inflammation/pain, delayed diagnosis, may require endometrioma imaging and excision specialist. Sleep targets 7–9 hours; reduce fragrances/plastics; omega-3 2,000–4,000 mg/day. Supplements listed: prenatal folate 400–800 mcg, CoQ10, myo-inositol 2 g 1–2x/day, NAC 600 mg 3x/day, omega-3 EPA/DHA, vitamin D if deficient (~4,000 IU/day after testing), and optional NMN (host anecdote: improved euploid embryos after NMN).

0:53Dr. Lara Brighten:today we're talking about science-backed ways to support your fertility because women are constantly being told one version of this story you're getting older so that's the only problem it could be i mean that's what i was told despite having a baby at 40 and at 41 every doctor i saw just kept saying you're too old you need ivf and as it turns out that was never the problem And listen, this is not to say that age doesn't matter. It does. I'm not going to lie to you about that. But if that's the only thing somebody is telling you about fertility, that's an incomplete conversation. That's why today we are talking about the difference between egg quantity and egg quality, how inflammation hijacks fertility.
1:38Dr. Lara Brighten:And we're going to definitely be talking a bit about PCOS, endometriosis, how those completely change the conversation. and I'm going to talk you through some of the top things you must be doing if you are currently trying to conceive. And yes, we're also getting into specific supplements and dosages and not take, you know, 27 pills and just try to manifest your way to becoming pregnant. By the way, I think that manifestation is a good practice, but I do want to ground this in science. And if you're new here, welcome to the Dr. Brighton Show. I'm your host, Dr. Jolene Brighton. I'm a hormone doctor, a nutrition scientist, and I'm someone who has struggled with secondary infertility.
2:20And if you can take a quick minute and subscribe, like, leave a review, that support would mean so much to me. Real quick, I do want to acknowledge that many of you have been asking for this episode for a very long time, especially as we were doing our endometriosis expert series. And I just want to say thank you for being patient with me. after I had my pregnancy loss last year. I've been very deep in grief and moving through that, but I understand that you need support, and I'm at a place where I feel like I can hold both
2:52Dr. Lara Brighten:my grief, my journey, and be able to support you, and that's exactly what I want to do in this episode. But I don't want to hold this up, so let's get into what you came for. Let's talk about that biological clock, but make it accurate. If you think fertility is about how many eggs eggs you have, I like to say this is like judging a restaurant by how many tables it has and never really asking, is the food any good? So we need to separate egg quantity from egg quality. Now, egg quantity is basically how many eggs do you likely have left? And your doctor will use anti-malarian hormone or an AMH if you're in the IVF process to try to estimate that for you.
3:37Dr. Lara Brighten:Egg quality is how likely are those eggs to fertilize, grow normally, and lead to a healthy pregnancy. Now, I'm going to tell you about one supplement that can help in this arena, but first I want to bust some myths about women, fertility, age, and we're going to throw in the male factor as well. So the first one is the cliff. Fertility doesn't stop instantly at age 35. It declines more significantly because both the quantity and the quality of the eggs is decreasing. But it's not like after age 35, boom, you're not going to be able to get pregnant. Now, when it comes to a rapid egg quality, people will tell you that that drops after age 35 as well.
4:21By age 35, about 35 % of women's eggs are lower quality.
4:26Dr. Lara Brighten:And as we get closer to 40, that's around 50%. But that doesn't mean you cannot still conceive naturally. If you're looking for a book that can help with some of these things, yes, you can get pregnant by Amy Robb. I think it's a great one because she integrates both conventional medicine and also her Chinese medicine practice. Now, this one is a big myth, and that is men can have babies forever. We now know that male fertility also declines. Starting in about their 40s, men start producing lower quality sperm. And that affects overall conception chances. So the chances of getting pregnant. And it can impact mom and baby's health during the pregnancy and sometimes long term as well.
5:12Dr. Lara Brighten:But what I want you to take away is that age is not the whole story. And pretending that's all it is isn't helping women. It's why so many of us get labeled unexplained infertility. or they just tell you that you're old and that you have to do IVF. I'm not bagging on IVF. As you guys know my story, I did IVF. But let's not pretend it's not expensive and not without risk and that not everybody gets the outcome they want, which is a baby in their arms. So as women, the reality is, is that you can have a woman with decent ovarian reserve, like AMH on paper looks good, and she could still have issues with ovulation, inflammation, insulin resistance, endometriosis, or just hormonal issues overall.
5:57On the flip side, you can have a woman who is younger and technically has more time,
6:03Dr. Lara Brighten:but her body is sending signals that something is off and she's still not able to get pregnant. So fertility is not just a birthday problem. It's also an ovulation problem, a metabolic problem. We're going to talk about inflammation in this episode. And sometimes it's also a diagnosis, you should have gotten years ago problem, but they put you on the pill instead and said, don't worry about it until you want to have a baby. I think it's also important to note that a normal basic workup does not always mean that your fertility has actually been evaluated in a meaningful way. It may be that no one has dug very deep just yet.
6:41And that matters because a lot of women are being reassured that, oh, you're young. Don't worry about it when they actually need answers or they're being told like, oh, you're old and that's all that's going on. I know I've said that a few times, but it's so important that if you've been struggling to get pregnant, you meet with a reproductive endocrinologist, especially if you're over age 35, especially if you know you have co-occurring conditions like Hashimoto's thyroiditis, which is hypothyroidism, endometriosis, PCOS, adenomyosis, celiac disease. The list goes on, and there's a lot of reasons to evaluate women's fertility sooner than later.
7:21Okay, so we can say, yes, age matters, but fertility is also more than age. And if someone's only focusing on your age, then they're missing real reasons that your body is struggling. Now, the supplement that can help your fertility is CoQ10. The ranges can be anywhere from 200 to 600 milligrams that you take three to four months before conception. This is especially helpful for women over age 35. So what CoQ10 does is that it boosts ATP energy, the energy of the mitochondria, and that supports your eggs. It's critical for proper maturation of those eggs. It also gives antioxidant protection. So it's going reduced reactive oxygen species that protects your egg and it protects sperm from DNA damage.
8:09Dr. Lara Brighten:There have been studies that show that CoQ10 supplementation is associated with increased egg maturation and improved embryo quality. There is also some research that suggests it can increase the number of retrieved eggs during IVF cycles in women who have had diminished ovarian reserve, but I would never want to say like this one supplement is a guarantee for you. So CoQ10 can help both natural conception and advanced reproductive techniques like IVF. And it does that by enhancing egg quality, increasing maturation rates, improving embryo quality, and there is some research showing that it can help with clinical pregnancy rates.
8:52So CoQ10 is definitely one to talk to your doctor about and consider on your fertility journey. Now I want to shift gears and talk about inflammation because as a woman with endometriosis
9:01Dr. Lara Brighten:and adenomyosis, I need you to hear about your inflammation and your fertility. Now, before I tell you how to lower inflammation fast, I need you to understand why inflammation even matters in this conversation because this is not just about like, am I bloated or am I retaining water or am I tired? Inflammation can make your entire reproductive environment less cooperative. It becomes hostile to your chances of conceiving and staying pregnant. And that's honestly a nice way to put it. So inflammation can interfere with how your hormones are able to signal to the cell's receptors. It can mess with your ovulation, worsen insulin resistance.
9:43Dr. Lara Brighten:It can affect the quality of the environment an embryo is able to develop in. It can disrupt sperm and egg's ability to meet, And it can create conditions that are not exactly making implantation any easier. Now, I want to be careful here because inflammation has become one of those words that people are throwing around like glitter. It's just, oh, inflammation. Everything seems like it's inflammation these days, right? And everyone's inflamed and all of that feels really stressful. So what we're actually talking about here is that the body is under repeated physiological stress. So it's chronic inflammation.
10:25Dr. Lara Brighten:Chronic inflammation is sneaky inflammation because it's creating symptoms that go unnoticed, but it's having a really big impact on your health and your fertility. Now, inflammation can come from things like blood sugar swings, insulin resistance. if you have really poor sleep or you're under chronic stress. As we get older and we accumulate more visceral fat, fat around our organs, that can lead to chronic inflammation. If we're eating a diet that's less nutrient-dense and it's more rich in ultra-processed foods, those fats can shift your inflammatory profile. Certainly things like drinking heavily, smoking, not moving your body, having a sedentary lifestyle, so not exercising regularly.
11:11Dr. Lara Brighten:Those can all contribute to inflammation. And in some women, chronic inflammatory conditions are existing alongside these same things. So like endometriosis, PCOS, celiac disease, adenomyosis, Hashimoto's, any autoimmune disease really. Now next week, I'm going to talk about how inflammation may be influencing the development of ADHD or autism in children. It will not be another blame mom talk or shame-filled lecture. It's going to be actionable and evidence-based. So make sure that you subscribe so that you don't miss that. Now, if we've got all this inflammation, why not just take an anti-inflammatory?
11:53I totally get that and I get asked this all the time, but the reality is that it could block ovulation and further hinder your chances to get pregnant. Now, one thing that can be leveraged here is progesterone.
12:08Dr. Lara Brighten:There is a myth that progesterone suppresses the immune system, but that's a oversimplification and just wrong. It doesn't suppress the immune system. It instead shifts it to being more tolerant to baby. And in that, it tells your security team that's your immune system to stop overreacting to everything. So your doctor may test your progesterone five to seven days post-ovulation. They may recommend progesterone therapy. But while you wait for labs, one move that you can make to drop inflammation quick is omega-3 fatty acids. Eating cold water fish, not just three times per week, but daily, and taking a quality omega at maybe 2 ,000 to 4 ,000 milligrams a day can help drop inflammation.
12:58Now, we're going to talk about stress reduction more.
13:01Dr. Lara Brighten:I know it sounds basic, but it's a biggie. So chronic inflammation demands a response from cortisol. Cortisol is a highly anti-inflammatory hormone, but chronically elevated, it can interfere with ovulation and progesterone production. But it's not enough just to deep breathe. I'm not going to tell you that because if you have chronic inflammation, we have to find that and address it. So it could be of endometriosis. It could be gut dysbiosis or even an infection. It could be autoimmune disease. Whatever it is, it has to be found and it has to be addressed because, you know, I would recommend eating an anti-inflammatory diet that's low in ultra-processed foods, rich in plants, high-quality fats.
13:45Dr. Lara Brighten:That helps inflammation immensely, but it will only take you so far if you do not address why you have that inflammation in the first place. So a fertility supportive plate is going to be colorful produce, healthy fat, lots of fiber. That's going to help your body with regulating insulin and inflammation. And please don't listen to anyone that's like, hey, you just need to do like a three-day detox and you won't have inflammation. If you have chronic inflammation, there's a reason for it. We need to figure out why the body is under attack. Will you also bring on anti-inflammatory therapies? Now, I mentioned PCOS and endometriosis.
14:25Dr. Lara Brighten:Those both, we know, are leading causes of infertility. And it's important if you're dealing with these conditions that you don't waste time in addressing them and seeing a medical provider who can help you and support you on your fertility journey. Now, I have other episodes on PCOS and endometriosis. I will link those in the show notes at drbrighton.com. PCOS is often an ovulation problem first. Women will have eggs, but they don't ovulate them regularly. and even if they do, they may not be the best quality because they have insulin resistance, inflammation, high androgens affecting the quality of that egg.
15:00Dr. Lara Brighten:In PCOS, I mentioned we see the insulin resistance. There's androgen excess, so that's that excess testosterone I was talking about. There's irregular cycles because your ovulation is irregular. There's also acne and hair changes, weight gain, difficulty losing weight. There's metabolic dysfunction at the core. And this matters because if insulin is high and blood sugar regulation is off, that feeds the whole system in the wrong direction. It becomes a pro-inflammatory direction and it causes the ovaries to make the wrong hormones. They're making more androgens than they are cyclical hormones of estrogen and progesterone.
15:38So with PCOS, blood sugar regulation, gut support, inflammation, anti-inflammatories coming in, and looking at how do we get you cycling regularly has to be part of the strategy. Now with endometriosis, that's chronic inflammatory disease.
15:56Dr. Lara Brighten:It's systemic. Women can have pelvic pain, pain with sex. So like, how can you get pregnant if you have pain every time you try to do it? One thing I hear from women all the time is that they're struggling with symptoms like hot flashes, sleep disruptions, and brain fog, but aren't sure where to turn to for help. Menopause is inevitable, but suffering through it isn't. That's why I want to tell you about Alloy. Alloy is a digital health platform that connects you with a menopause-specialized doctor who can create a personalized treatment plan tailored to your needs, all from the comfort of your home.

That's M-Y-A-L-L-O-Y dot com code Dr. Brighton. They can have bowel symptoms, fatigue, anxiety, and the pelvic environment becomes hostile when it comes to the fertility conversation. Depending on if you have endometriomas or not can impact the quality of your eggs. So you want to have imaging, have an evaluation with an endometriosis excision specialist because sometimes you may need to go the route of IVF, but they may suggest they remove an endometrioma first.
17:43It's all going to depend on what your AMH is, what your health history is, how large the endometrioma is, what your past history is of
17:52Dr. Lara Brighten:getting pregnant. And so it's important that you work with a team, not just a reproductive endocrinologist. There are some who will just put you through IVF cycles without a care in the world of what happens to your endometriosis. And there are others who understand endometriosis and they will work alongside an excision specialist. They'll recommend you to an excision specialist. That's a green flag in a reproductive endocrinologist. If they're like, I'll just go in, I'll do a little bit of surgery. We'll see what we can do. Like, no, you want a full excision if that's the route you're going to go.
18:25Dr. Lara Brighten:So with PCOS versus endometriosis, we want to think ovulation, insulin resistance, metabolic signaling with PCOS. Endometriosis, we're thinking lots of inflammation, pain, pelvic environment is disrupted, and women usually have a delayed diagnosis. And some women can have both because apparently the body sometimes likes to be aggressively unhelpful. Now, if you are feeling overwhelmed at this point and you don't know where to start, I don't want you just starting with anything and just trying to throw everything at yourself or doing some weird supplement stock that somebody on TikTok swears changed their life.
19:05I want you starting with very specific non-negotiables. If you're in my endometriosis reset course, You know how I love my non-negotiables.
19:13Dr. Lara Brighten:So here are the big areas that we have to care about first. So stress regulation, sleep. We need to be thinking about nutrition. I mentioned it a bit earlier. Movement. Remember, a sedentary lifestyle is associated with chronic inflammation. And we have to reduce environmental toxins. These matter in the fertility conversation. Now, why all of these things matter is because they're influencing hormone signaling. They influence your blood sugar, inflammation, ovulation, the basic physiological environment that your body is operating in to help you get pregnant and stay pregnant. And I know they're not glamorous.
19:56And that's exactly why so many people skip them. And instead, they go to like, what is the bright, shiny object? Everybody wants a fertility hack, but the reality is, is that the fertility foundation is what we all should be working on because the foundation is what makes the other hacks because some of those supplements do work, like right? CoQ10. They matter, okay? The foundation matters. So we're going to go through them one by one, and I'm going to have a supplement list for you that you should consider talking to your doctor about and seeing if it's right for you on your fertility journey.
20:31Now, we got to talk about an ugly truth.
20:33Dr. Lara Brighten:You cannot expect a hormonally stable, fertile body out of a nervous system that thinks it's being chased by a bear every night at 11.47 p.m. Okay, so sleep is not a luxury. It is endocrine maintenance. And so poor sleep, that can impact your insulin sensitivity, your appetite regulation. It definitely affects stress hormones. It can increase inflammation and it also hinders your body's ability to recover, which is especially important if you do go through IVF. So if you're trying to conceive and you are sleeping five and a half hours, scrolling in bed, waking up wired, pretending that it's fine because you're used to it, I want you to know that your body is not used to it.
21:21Dr. Lara Brighten:Okay? And that doesn't mean your body likes it either. So I'm not judging you, but this is where I need you to shift and I need you to be boring and consistent and a grown woman doing sleep hygiene. So aiming for seven to nine hours, ideally getting a regular bedtime, waking up at the same time every day, even on weekends, opening up your curtains, getting morning light exposure, less caffeine later in the day, cool dark room in the evening, and stop treating your phone like an emotional support animal. Well, put it away. Put it away 30, 60 minutes before bed. Because if your sleep is chaotic, your hormones are going to be chaotic.
Read the full transcript
22:04And if you are on your phone looking at stressful things, that's going to disrupt your nervous system. So here's an action step for you. For the next seven days, just want you to pick one sleep goal. What's it going to be? Consistent bedtime or no caffeine after 12 p.m. Morning sunlight within an hour waking. Just pick one of the things I said and just start there. Just one thing at a time. We're moving on to stress. No, I'm not going to say just relax and you'll get pregnant. I literally hate hearing that so much because that advice, it deserves jail. Straight to jail. Anyone who says that.
22:40Dr. Lara Brighten:Now, when I talk about stress, that doesn't mean that if you have a busy job or a hard season, you're completely doomed. What it does mean is that chronic physiological overload can worsen your inflammation. That can disrupt your sleep. That might be messing with your sleep. It's going to affect your blood sugar, and it's going to stress your systems that are already struggling, and it's certainly going to impact ovulation and progesterone. Now, I'm not blaming you, okay? This is not about blame. It's more about the load, and the question is not like, am I stressed? The question I want you to ask is, how many stressors is my body carrying without any real recovery?
23:22And we have to face it. If you have chronic inflammation, if you have a chronic condition, you are under stress from that. And most women, when we ask them, like, how many stressors are you carrying? The answer is too many. They're like underslept. They're under eating protein. They're over caffeinating. They're over committed. They're doom scrolling, maybe even over exercising. And so these things can make your cycle and your hormones feel chaotic. And that's because this kind of stress, it signals that we need to survive. That's the priority, not trying to get pregnant because the environment is just too dangerous.
24:01So an action step for you is to pick one nervous system downshift that you will actually do. Okay? Which one will you actually do? Not which one is like, oh, I'm going to put that on my calendar and it's just going to stress me out more. So maybe that is five minutes of slow breathing when you wake up, or maybe it's a 10-minute walk after dinner, or maybe it's not hanging out with those people that make you feel absolutely wrecked and bad about yourself after you've been with them. Just pick one way to start down-regulating that stress. And I will link in the show notes an episode on the vagus nerve stimulation because that's a really easy one to get you into parasympathetic rest and digest activity pretty quickly.
24:44So we talk about nutrition for fertility. We need to focus on the things that are going to help with hormone production, mitochondrial function. We want to eat in a way that's already for early fetal development, like eat as if you're pregnant. And so we don't want to try to be perfect because that's a stressor. We want to try to be consistent with things like having protein at every meal, trying to hit 25 grams minimum of fiber every day, making sure we're eating enough total calories and that the food that we're eating has, it's rich in micronutrients. So getting rid of ultra processed foods, that alone will shift you into more nutrient density.
25:26And then of course, we want to focus on blood sugar stability.
25:29Dr. Lara Brighten:Okay, now let's talk about the supplements that women always ask about. So, of course, if you're trying to get pregnant, you should be on a prenatal. A prenatal, ideally, with at least 400, maybe more like 600 to 800 micrograms of folate coming in every day, mixed with B6, B12, and minerals. CoQ-Tan, I already mentioned at the top of this episode. This is one of the most common that's discussed for egg quality, ovarian reserve. and if you are someone who has been struggling trying to conceive or you're over 35, hitting that 600 milligrams a day, usually 200 milligrams three times a day, that's where the evidence is really at.
26:10It's an expensive supplement, which is why we'll say, oh, you know, 200 to 600 milligrams. Some women are doing 800 milligrams, but getting CoQ10 in can be really helpful. Now, mywinositol is a really well-studied nutrient. it's very commonly studied at two grams one to two times a day this is especially relevant for
26:31Dr. Lara Brighten:women with PCOS because inositol may help with both metabolic health and regular ovulation and egg quality the studies are mixed on you know pregnancy outcome data but I want you to understand that's because you cannot just take a supplement and expect that you will get pregnant and if that on this podcast, you probably already know that. It takes a multidisciplinary approach. Nacetylcysteine is something that is commonly used for PCOS and endometriosis. The dose is usually 600 milligrams three times a day for fertility. That's also the same dose for endometriomas. And so NAC is a precursor to glutathione.
27:15Glutathione is a very potent antioxidant that protects the quality of the eggs. It protects all of your cells in your body from free radical damage. We mentioned omega-3s already for dropping inflammation. However, a combination of EPA and DHA, which by the way, you will not get enough in any prenatal that's out there.
27:36Dr. Lara Brighten:You need to take it separately. Taking fish oil, it's going to support inflammation. It's relevant for PCOS and endometriosis especially. I don't want to make it out to be this like standalone fertility fix, but it's really, really important for your nervous system. So nourishing your nervous system, but also baby's nervous system, and it can help with insulin as well. Now, if you are deficient in vitamin D, well, hopefully we'll catch you before you're deficient. So if you're low in vitamin D or you are deficient, you're going to need to supplement with vitamin D. So you'll need to get a blood test.
28:12Dr. Lara Brighten:And then typically it's 4 ,000 IUs daily that you would be supplementing with to bring your vitamin D levels back up. Now, this is a test and treat. This is not a like, let's just guess. Usually, you know, prenatals will have like a thousand IUs in it. That's totally fine. You know, even some people will do 2000 IUs, test their blood, they're not going high. But what we don't want to do is think vitamin D is good. It helps my fertility. So therefore, more is better because it's a fat soluble vitamin. It can be problematic at high doses. Now, the other supplement that has less research to back it up, but I have found in my own fertility journey was very, very helpful, was NAD, more specifically NMN, which is a precursor to NAD.
29:00And I took that every day and so did my husband. We did an egg retrieval and we got lots of embryos, but none of them were euploid. According to the BGTA testing, which we know is not 100 % accurate. We took NMN and then we got three euploid embryos. So there is something to it. We need a lot more research before we start recommending this like across the board for everybody, but I think it's a supplement worth mentioning. And then the last thing I would say is to check your thyroid health because if your TSH is elevated, even above 2.5 for some people, they'll find that they don't ovulate as regularly.
29:41They struggle to get pregnant. And in IVF procedures, it may be that adding a little bit of thyroid hormone really helps with that egg maturation. Your thyroid health is super important because surrounding the egg in that follicular fluid, there's actually thyroid hormone present. So it has a role. We just haven't researched it thoroughly enough. Now, when it comes to exercise and fertility, it should not look like punishing your body. And if you are, and you're punishing your body into submission, we don't get surprised when your hormones get kind of weird. So movement does matter.
30:15Dr. Lara Brighten:I'm sure you're aware. So we've talked about the inflammation, there's insulin sensitization, there's circulation in your body, so circulation to your pelvis, your metabolic health, and your hormones overall. If you have PCOS, you have to be doing exercise. So everybody needs to be doing strength training, cardio, but also exercises that help them wind down and nourish their nervous system. Sometimes women hear exercise helps hormones. They go super intense. Intense, anything. So whether that is exercise or dieting, these things, they disrupt safety signals to the body. They can make getting pregnant, staying pregnant harder.
30:55So we do want to move regularly. We want to strength train. We want to do our cardio. We want to engage in walking, in neat movement, which is basically like you don't have an exercise plan.
31:06Dr. Lara Brighten:You're just moving your body throughout the day because that's just like part of living as a human. And then again, looking at things like maybe it's Pilates for you. Maybe it's yoga. Maybe it is, you know, just doing some deep stretching in your garden or something that helps you tonify that parasympathetic nervous system. Now, if you're someone who's going from a sedentary lifestyle, starting with like 10 to 20 minutes of walking like every day or even twice a day, that can be the sweet spot for you. If you're struggling with exercise, you haven't been exercising in a while, you have a medical condition, meet with your doctor, make sure you get clearance there.
31:41And then maybe work with a physical therapist, occupational therapist, or maybe even a personal trainer to help you get started in a way that matches what your body's needs are. Okay, well, I saved the best for last or maybe the worst for last because I got to talk to you about environmental toxins. Now, I don't want you becoming paranoid and throwing out everything in your house by tonight because you listen to this podcast. I want you making the biggest impact swaps without turning your life into like a full-time chemistry project where you feel like you have to read every label at all times always.
32:15But when we talk about reducing toxins in fertility, what we're talking about is lowering the unnecessary exposures that may affect your hormones, your fertility, your partner's fertility as well. And this is, again, I don't want you to stress out. It's not about being perfect. But it's about looking at what you control, what in your environment you can change, and focusing there. So, of course, if you're smoking, that's got to stop. If you are drinking heavily, which is having more than two drinks a week, it's got to stop. Plastics, you don't want to reheat your food in it. You want to reduce that.
32:55So start in your kitchen, moving out the plastics, replacing them with glass.
33:00Dr. Lara Brighten:It can even just be mason jars. I always tell patients just to start with these three things. The plastics that you're eating out of, your air quality. So maybe you want to sleep with an air purifier in your room, but you definitely want to start eliminating fragrances, Glade plugins, yeah, I'm calling them out, Yankee candles, those kinds of things, and then take off your shoes before you come inside. That can help with environmental toxin exposure, and it's a really easy move. The other thing is to buy organic when you can, but wash your produce. That is super important. And we don't buy organic because we're like, oh, it's more nutrient dense.
33:39I hear this argument all the time of like, don't buy organic. It's not more nutrient dense. I'm like, duh, we know that. We buy organic because it is less pesticide exposure on us with endocrine disruptors that affect our hormones. And also because we care about the people who grow and harvest our food. And the conversation around organic does not always need to be just about the individual. We also need to think about the people who grow and harvest our food and make it possible that all we have to do is go to a grocery store and eat. So look at your personal care products. If I had to start with one thing, I'd say fragrances.
34:17And look at the bottle as it's getting to the end. That's a good opportunity to say, okay, when I get to the end of this, I'm going to have a swap.
34:24Dr. Lara Brighten:And it buys you time to make that swap. Now, if you take nothing else from today and this episode, it is that fertility is not just about age. It's age and egg quantity, egg quality, inflammation, metabolic health, the diagnoses you have, the daily inputs that are shaping your hormones. And if you feel overwhelmed, come back to the non-negotiables we talked about today. So where can you just take one step today? Sleep, stress regulation, nutrition, movement, and reducing environmental toxins. Again, if you can just start cleaning up the air in your house, you're making one positive move for your fertility.
35:08And this is the foundation.

What if targeted, evidence-informed changes to daily habits could improve your chances of conceive without turning your life upside down? In this episode, I walk you through a practical fertility protocol that centers metabolic health, ovulatory function, and simple habit shifts that actually stick. I focus on what the data shows is most actionable—which labs to run and how to interpret them, which nutritional strategies and supplements have the strongest evidence for preconception support, and how sleep, stress biology, and circadian alignment shape your fertile window.
I also cover quick environmental wins to reduce chemical and thermal exposures that can undermine reproductive outcomes and share short-term strategies you can implement this week while you pursue longer-term optimizations. This isn’t about one-size-fits-all promises; it’s about prioritizing changes that change physiology, using markers we can measure, and tailoring the approach to where you are now in your cycle and life.
If you’re trying to conceive or preparing to, I designed this protocol to give you clarity, measurable steps, and realistic timelines so you can act with confidence.
