The Secret Powers of Ovulation (It’s Not Just for Making a Baby)

benefits of ovulationOvarian hormones estrogen and progesterone are beneficial for health. That means natural ovulatory menstrual cycles are beneficial for health because ovulation is how women make hormones.

Does that surprise you? Men make testosterone every day, so you might think women do something similar, but we don’t. Instead, women make hormones as a surge of estradiol leading up to ovulation and an even bigger surge of progesterone after ovulation.

It’s an elegant system that sometimes results in a baby. Even when ovulation does not result in a baby, it’s still worth doing because regular ovulation delivers the beneficial hormones that the body absolutely expects to have.

Benefits of ovulation

Every monthly dose of estradiol promotes muscle gain, insulin sensitivity, and the long-term health of bones, brain, and the cardiovascular system.

Every monthly dose of progesterone reduces inflammation, regulates immune function, and supports thyroid, brain, bones, and breast tissue.

The benefits of ovarian hormones are both short-term by making women stronger, and long-term by building metabolic reserve and health.

According to Canadian endocrinology professor Jerilynn Prior, “women benefit from 35 to 40 years of ovulatory cycles, not just for fertility but also to prevent osteoporosis, stroke, dementia, heart disease, and breast cancer.” In that sense, each and every ovulation is like a monthly deposit into the bank account of long-term health.

For Professor Prior, ovulatory cycles are a “creator of good health.” They’re also an “indicator of good health” because when we’re healthy, ovulation arrives smoothly and regularly. When we’re unhealthy in some way, the lack of ovulation can tell the story.

The American College of Obstetricians and Gynecologists (ACOG) agrees. In December 2015, together with the American Academy of Pediatrics, they quietly issued a groundbreaking statement called Menstruation in Girls and Adolescents: Using the Menstrual Cycle as a Vital Sign. In it they state that doctors should always ask patients about menstruation and advise girls to chart their cycles. By doing so, they say, “doctors will demonstrate to patients that menstruation is an important reflection of their overall health.”

Learning to observe, chart, and interpret an ovulatory cycle is called body literacy, a term coined by menstrual activist Laura Wershler.

I invite you to think of ovulation as a valuable, health-giving event. I would go so far as to say that if you’re not thinking about ovulation, you’re not thinking about health.

Obstacles to ovulation

Hormonal birth control

Hormonal birth control stops ovulation, which is, of course, its purpose. It switches off ovarian hormones and replaces them with contraceptive drugs like ethinylestradiol and levonorgestrel which can cause hair loss and other side effects.

👉Tip: There’s no progesterone in any type of birth control.

The physiological difference between our actual hormones and the contraceptive drugs of birth control affects every system in the body. Compared to women who cycle, women who take contraceptive drugs have altered brain structure and a greater risk of depression and autoimmune disease.

Undereating and undereating carbs

Losing ovulation and periods because of undereating is called hypothalamic amenorrhea. It’s not a disorder, but rather a smart, adaptive decision by the brain to pause reproduction when there’s not enough food to safely make a baby. Read Are you eating enough to get a period?

Polycystic ovary syndrome (PCOS)

The hormonal state of excess androgens or testosterone can cause anovulatory cycles (cycles with no ovulation) and is usually associated with insulin resistance. Reversing insulin resistance with diet, exercise, and natural supplements such as inositol can help to restore ovulation.

👉Tip: Before you embark on any kind of calorie-restricted or carb-restricted diet for PCOS, take care that your diagnosis was not based solely on an ultrasound or an AMH blood test. Those tests are not reliable and may have resulted in you being told you have PCOS when you actually have hypothalamic amenorrhea. Read PCOS cannot be diagnosed by ultrasound.

In conclusion, ovulation is important for women. And not just to make a baby.

Gloria Steinem said that if men could menstruate, menstruation “would become an enviable, worthy, masculine event: Men would brag about how long and how much.” I would take it a step further and say that if men had to ovulate to make testosterone, they would never stop talking about it.

  1. Hi Lara,
    I am wondering what birth control you would suggest for teens. My daughter is 16 and has a steady boyfriend. They use condoms but honestly I don’t trust that this will be safe enough. Her periods are not that regular (3 to 5 week cycles), so ovulation might be all over the place. Being a teenager she won’t track her temperature. I dislike the idea of the pill, but don’t think an IUD at her age is adequate either. I would love to hear your thoughts about it. Thank you,

    • Thank you very much for your prompt comment. Excuse my ignorance but I am not sure what you mean with Plan B and the two 750 µg levonorgestrel pills?

  2. Hello Lara!

    Where can we read about Jerilynn Prior, “women benefit from 35 to 40 years of ovulatory cycles, not just for fertility but also to prevent osteoporosis, stroke, dementia, heart disease, and breast cancer.”? Thankyou!!!!!

  3. I haven’t read your books yet but herenis my question. I am 64 years old, had a total hysterectomy 9 years ago due to a very.large fibroid cyst and a couple smaller ones. Non stop bleeding for years. I have been on hrt for a number of years…estriodol (Bi-est) and progesterone capsules wuth regular bloodwork to monitor levels. I wonder if you recommend this at my age and do I just continue forever?

  4. Thank you Lara, your book and articles have helped me so much! I shared this particular blog post in response to an article in a UK national newspaper where a gynaecologist claimed there to be no health benefit and no reason for women to have periods. I was shocked at how many women took offence at the idea that natural, ovulatory cycles are necessary for long term health. I could understand their frustration at having suffered due to hormonal problems, I suffered enough myself over the years, and it was easier to put a stop to it by going on the pill—until that started to cause other problems that is. Thanks to charting my cycle I’ve come to understand so much about my own health, and it’s an extremely reliable birth control method. Like many women, I probably won’t make it to 35-40 ovulation cycles in my lifetime. Is there anything we can do to make up for what we missed, Lara? x

  5. Hi Lara! Thanks for the work you do.

    I’d love to get your opinion on something:

    I have PCOS (almost certainly insulin resistance PCOS with high testosterone and inflammation) and I do ovulate however it takes a very long time (currently I’m on day 65 pre-ovulation). The second half of my cycle is always exactly 2 weeks, so no issues there (I have been using bio-identical progesterone cream after ovulation).

    I’m taking almost all the supplements that are recommended for treating PCOS (in fact, I worry I’m taking too many supplements…) and have a relatively healthy diet and lifestyle, so I’m wondering what will help with shortening the first half of my cycle?

    I’ve heard taking bio-identical estrogen until ovulation might help, but I worry this could make things worse? (in case I’m estrogen dominant)

    And if you do recommend I take bio-identical estrogen in the first half, should I start this now (on day 65) to hopefully induce ovulation this cycle?

    Thanks so much in advance!

  6. This was a great read. So- in regards to all these hormones, what do you recommend for someone who gets a migraine with EVERY period. Mine are so debilitating. It’s all hormonal, so what could I do to prevent such horrible symptoms?

  7. Sorry Lara for too many questions however l m really curious to know. As you mentioned about ovulation s health benefits and l m being on HRT at the age of 37, despite the fact that l won t be deplated from the hormones l will be missing otherwise,but this still doesn t mean that l will be ovulating. Will be bidy mimic ovulating without ovulating and benefit regardesly ? Thank you so very much.

    • Yes, body-identical hormones estradiol patch (Estradot) and oral micronized progesterone capsules (Prometrium or Utrogestan) are real hormones so they give the same benefits as ovulation.

      There’s probably no reason to take Vitex in your situation.

  8. Thank you so much, l will try to purchase your book.Do you think l can take Vitex alongside the HRT l m taking? Would this be dangerous or mess up my hormonal system? I would have wanted to do so in case it helps for ovulation. However l don t feel confident to do so.

  9. Dear Lara, I see that you didn t mention Premature Ovarian Failure as l also searched for in your blog. I was diagnosed with it at the age of 32 and after refusing HRT for the past 5 years l have recently started to use oestrogen patches and natural progesterone due to my fear of facing with the health consequences in later life. I would love to hear your comments about this, whether or not if l did the right thing with starting HRT. My elder sister was diagnosed with the same thing when she was 39 and her periods have stopped afterwards just like mine did. However l still get 2 to 3 periods in a year. Both my elder sister’s and my periods were regular before we hit the premature menopause time but have all the time lasted 2 to 3 days max. Do you think this was a genetic condition? Thank you and looking forward to hear from you.

    • In my book Period Repair Manual, I briefly discuss premature ovarian failure and how the best treatment is to take body-identical estradiol patch and oral micronized progesterone capsules. (I think what you’re taking.) Because, yes, the hormones can help to prevent osteoporosis and other long-term problems.

  10. How do I track ovulation if I have insomnia and wake up multiple times a night? I can never find a pattern with my temperatures. But I have predictable cycles with egg white mucous two weeks before menstruating.

  11. Thank you for the clarification, and for your good work making everyone aware of the importance of our hormones. I understand you weren’t slamming men, but using a contrast to show the difference in how male and female hormones are treated. It boggles the mind what we’re not told.

  12. Maybe the slam on men in the last comment would have made sense 50 years ago, but there is an army of female doctors happily profiting off of such a destructive view of women’s health.

    As well, feminism has absolutely promoted the pill as a women’s liberation issue and necessary for our freedom.

    It’s disingenuous to frame this as just a male dominance issue and time to take ownership of the major feminism fail that fell for it and led us astray.

    • yes, I’ve had some push-back on that sentence. I honestly did not mean it as a slam on men but rather as a “reframing” of women’s hormones as something important for health. Just as we all accept that men’s hormones are important for health.

    • I did not find the statement at the end of the article to be a slam on men at all, but more of a call on women to feel empowered by our periods and not be afraid to talk about it. It actually made me chuckle because it’s so true!

  13. Hi Lara! In Denmark there was an article saying that our ancestors didn’t have as many menstruations as we do today since they spent most of their fertile years being pregnant – and the article concluded that the menstruation (and ovalution) was an abnormality.

    If ovulation is so beneficial for us, I wonder what effect it would have had on our ancestors to not have it as frequently as we today? And if we are better off – or worse – by having more cycles in today’s world?

    P.s. I’m a huge fan of your work and I’m spreading it as much as I can in Denmark, I was part of Nicole Jardim’s apprenticeship and loved our live call with you!

  14. Hello Dr Briden
    For how long should you take e.g. zinc/magnesium/iodine or cut out a certain food to see a difference in ovulation? Is 3 months enough, and if you still have irregular periods after that, stop that treatment and start another one?
    (unfortunately the doctors in my country don’t know much about PCOS so I have to do the trial and error way)

  15. Hi Dr, Briden, Thank you for your work.
    At age 36 after 2 miscarriages (due to chromosomal abnormalities) and tests I was told that I have very low amount of eggs left and that I am in early perimenopause. In your book, as I understand it, it says it is very important for people who enter into perimenopause to seek hormone therapy because the potential lack of hormones that are so helpful with ovulation could be harmful to health at that young of an young age (I know 37 isn’t that young, but my doctor said my fertility system seems more like a 45 year olds). I am still having my period, but the cycles are getting shorter (24 days or so instead of 28) and the actual days of menstruation are shorter at ~3 with only one day of moderate bleeding. I went to a midlife specialist and she said I don’t need to see her until I stop having my period. (She was rather dismissive of me in general which was difficult since I just learned I likely couldn’t conceive) Do you agree that I should wait until I have no period to seek out hormone therapy? I want to do what I can to protect my long term health and I don’t wish to take birth control as a “catch all” for the reasons stated in your book. Any advice is so greatly appreciated!

  16. Hi Dr. Briden!

    I’m 19 and have struggled with acne and about 2 periods a year since I was 16 (and recently 20 day cycles). My androgens are normal so I do not suspect PCOS. I am completely healthy physically, but I got a food sensitivity test back that my naturopath said was the worst she had ever seen! I react to almost every food, even foods I haven’t eaten for years. Have you ever heard of something like this, and do you think I should pay attention to it when I do not have any digestive or even non-digestive symptoms of sensitivities? I also have eaten healthy and paid good attention to my gut health for the past few years, so it just makes no sense. Thanks! 🙂

  17. Hello, Lara. Have an unrelated question. I always have a white coating on my tongue that is thick and won’t go away no matter how much I brush. I think it’s a yeast overgrowth. I have taken many antibiotics over the years for recurrent vagina infections. Back to back for years. I’m quite sure my bacterial/yeast balance is damaged. I have a sensitive stomach and now maybe a very lot less good bugs, so don’t feel an herbal anti-biotic/fungal is the best route. I do best on single strain probiotics. For some reason, the multi-strains cause me to bleed vaginally (I believe this is due to PH change, but doctors don’t have an answer). Acidophilus hasn’t really helped with the coating on my tongue. Looking for maybe a few strain options you think may help? Also, would you recommend opening capsules & swishing them in my mouth? Just looking for a good plan on what to tackle here. For some reason, when I go low carb, it seems it gets even worse & my breath really stinks and doesn’t stop stinking & my mouth tastes bad. I do have adrenal PCOS. I have once heard weakened adrenals weaken your ability to control your good and bad bugs. I just don’t know what to do. I’ve tried several things for my adrenals such as magnesium, zinc, D3, Multi Vit, L-Theanine, Fish Oil, D-Chiro-Inositol, Myo-Inositol and nothing has ever made me feel better or improved anything regarding my PCOS, poor energy levels or this coating on my tongue. I’ve been trying hard for years. Sincerely, A Blog Fan

  18. Where in your book could I find some information about taking at the same time a contraceptive pill and extra natural progesterone through a gel? Are there any risks of getting pregnant? Does taking natural progesterone (gel) interfere with taking the pill (for contraception)? Thank you.

  19. Dr. Lara,

    I am 29 years old and have been missing my period for a year and 3 months since getting off birth control. I was told I had PCOS, but after reading your book and reading No Period Now What I am 90% sure it is HA. I have been “All In” 4 months and my LH went from .9 to 9.9, FSH is now 6 and Estridol has been stuck at 36.

    I have gained 20+ pounds and still no period. The only good sign is that my hair was falling out like crazy amounts and now seems to be normal shedding. I want to start a family, but don’t know how much longer this is going to take or if I should try treatment or wait longer…just so confused how some people do what I am and get their period back in a month.

    What are your thoughts or advice?

    • You’re probably getting close. 4 months is still early days.
      It can take 6 months or more. Your hair is a good sign. Other good signs would be if you’re noticing any hormonal signs like breast swelling or increased vaginal discharge.

  20. Hey Lara,
    I have this question ive wanted to ask you for ages! I hope you can answer.
    I am on the pill, i have tried the copper IUD but my body didnt respond well to it. Im not a big fan of the pill but i take it cause i dont know what else to do. Im not in a relationshio right now but when it may come to that time im not sure what else do to about contraception. I dont trust tracking it alone or condoms alone as when i was not taking any contraception my periods would come at different times every month. At least a week early every month.
    Just wandering if you have any suggestions on what i should do. I know i have been just having pill bleeds as they are lighter than normal and it just doesnt sit well with me.
    Thanks so much
    Katie – chch!
    Great talk at body fix 🙂

    • Hi Katie,

      thanks for coming along to the talk last night. I discuss contraceptive methods in Chapter 3 of period repair manual and also my blog post “The 5 best types of natural birth control.”

      Daysy is a good option and is available in New Zealand.

      Also, it’s worth pointing out that condoms-alone are a reasonable method of contraception, especially if using good quality condoms and with the back-up plan of the morning-after pill in the unlikely event of a condom failure.

  21. Hi Megan,
    When I came off the pill at 34 after being on/off it for about 10 years, I was hit with acne like I never knew. It ruined my life, my confidence, my dating/social life, mental health….I’ve tried everything from topical to acupuncture to colonics. I am now 39 and I have to say it’s clear except for the occasional breakout due to stress/diet. My best advice is to balance your hormones and give it time to balance out. Get your sleep right, get your diet right, eliminate the unnecessary things that promotes hormonal imbalance like alcohol/caffeine/dairy/xenoestrogens from makeup/bodycare. Simplify your diet, clean up your beauty routine/products, sleep, and most important manage your stress and give it time. It will go away, there is hope. The less you do the better.

  22. Hi Lara,
    I was wondering if you could please do a post on PMS acne and how to treat it? I’ve been battling PMS acne since coming off the pill a few years ago and I feel like I’m at my wits end and I’m so close to going back to the Dr for a prescription for the pill. I’d really really love to hear back from you!

  23. Hi Dr! I had been on a mini- pill may be Progestin only pills, since 1.5 – 2 years! Last month I came off it. So after how many months can I expect myself to ovulate being a PCOS girl! Also, will this absence of ovulation as well as menses going to aggravate my symptoms of hair loss/ excessive hair growth?

  24. Dr. Briden, I saw that you recommended cyclical progesterone therapy in your book for those with PCOS. Do you think this is a first line treatment and would it work for those with post-pill PCOS as well as other types? I have elevated LH after birth control and am TTC. Had normal periods before the pill so am disappointed to have to go straight to fertility drugs just to ovulate.

  25. Hello!

    I just read half of your amazing book The Period Repair Manual, and I’m working on the second half now. I’ve been struggling for five years with extreme menstrual pain and heavy periods. I finally was able to go to an endocrinologist last week and he wants me to get blood tests for LH, FSH, Estradiol, Progesterone, TSH, FT-4, Pregnenolone, 170H Progesterone, 170H, DHEA, Sulphate, Fasting Glucose, and Insulin. From reading your book I believe there is a certain time of the month to test these. My doctor didn’t seem to have enough knowledge on the subject so I am reaching out to you for help. He told me I can just go get them all tested on the first day of my cycle, but I don’t think this is correct. If you can help me, I would so greatly appreciate it. Thank you for the wonderful book! It is the best I have read so far on the subject.


  26. Hi Dr. Briden,
    Do you have any comments for the moms who are nursing their babies past 1? I currently am still nursing my 16 month old (who is my 3rd child), and with every child I don’t regain my cycle until they’ve completely weaned plus a few months. Lactation completely shuts down my cycle and I’m wondering if it would be better to wean earlier rather than forgo the hormones from having a cycle? thanks!

  27. It seems that after menopause we should be grateful for having enjoyed something we lack now. But the reality is that after menopause I have better health than ever,I am strong, fit, happy , with good sexuality and good sex drive, a lot of energy and looking hot. I don’t feel as I have no hormones. I think that maybe there is something about menopause that isn’t still well known , otherwise it couldn’t be possible. I’ve been without my period for four years and I don’t have any type of hormonal replacement, just eat well and exercise, but I’m better than my friends in their 30’s and 40’s.

    • thanks so much for sharing your story! Yes, I know a few women like that. And we do continue to make some estrogen after menopause, so yes, we can continue to be well.

      And after menopause, we still benefit from our previous exposure to decades of estrogen and progesterone.

    • The topic of my next book! I also speak about menopause in Chapter 10 of Period Repair Manual and how the fact that we had to eventually lose estrogen and progesterone should just make us more grateful to have had them at all.

  28. Dr Briden, why do I have low progesterone at 37? 17 oh progesterone is only 1.2 ng/ml 1 week before period. BBT charting shows temperature rises, but luteal phase only lasts a week. I have no PCOS, eat vegetables, fruit, rice, consume a lot of goat and sheep milk products and eat meat (when it is prepared in curries). What do I do to fix low progesterone?

    • Hi Kristina! I just happened to read your comment. I am curious if you have or have had breast implants or any type of foriegn implant? I had breast implants for 3 years that wrecked havoc on my heath, including hormones. I had them removed a year ago and have slowly been getting better. Breast implant illness is real and I know it’s affecting a lot of women who are still unaware of what’s making them sick, so I had to share just in case! ❤️
