While there are not many herbs that have been shown to benefit both male and female fertility, Tribulus terrestris is one of them. Tribulus has been used as a traditional fertility herb for years, in both Traditional Chinese Medicine (TCM) and Ayurveda. Traditional healing practices are rooted in time tested results, but scientific researchers in Bulgaria wanted to know how this herb really works. Several studies have been conducted to find out how Tribulus aids fertility, for both men and women.

Studies show the following fertility benefits:

  • Increase in sex hormone production in both men and women.
  • Increase in serum follicle stimulating hormone (FSH) and estradiol in women.
  • Increase in luteinizing hormone (LH) and testosterone in men.
  • Improvement in sexual desire in both men and women.
  • Overall fertility tonic for the male and female reproductive systems.
  • May help to normalize ovulation in women with anovulatory infertility when used prior to ovulation.
  • Increase in sperm count, motility, and health.
  • Decrease in the effects of antisperm antibodies.
  • May aid the male body in producing DHEA to treat erectile dysfunction.
  • Protective to liver health; raises glutathione (strong antioxidant) levels which are important to cellular health and immunity.

Tribulus for Male Fertility

Erectile Dysfunction
The main part of Tribulus that aids in fertility for men, is a constituent called protodioscin. This constituent helps to improve DHEA levels in the male body. In men with erectile dysfunction (ED), it has been found that they have low levels of DHEA. Some studies have shown that protodioscin, extracted from Tribulus, increases natural DHEA levels needed for proper erection. Protodioscin is also the main constituent that is responsible for Tribulus’ aphrodisiac qualities. An increase in sexual desire when using this plant has been reported by both men and women.

Antisperm Antibodies
Antisperm antibodies are the result of the body having an immune response to semen. This can happen not only to men, but to women as well. Antibodies that are triggered during the immune response work to kill the sperm because the body identifies them as foreign invaders.

    Antisperm antibodies may damage healthy sperm, causing poor sperm health.

    High numbers of antisperm antibodies in women can make it difficult for the sperm to reach the egg, and/or fertilize the egg. The heightened immune response may also affect conception.

In rare cases, both partners can have antisperm antibodies. In this situation, conception can be very difficult due to a combination of poor sperm health and the woman’s antisperm antibodies attacking the sperm. When the sperm is deposited in the vagina during sexual intercourse, the sperm will then be attacked by the woman’s antisperm antibodies and the sperm that is of poor health will likely be killed. This greatly lowers a couple’s chance of conception.

A Bulgarian study published online at showed that Tribulus can help to reduce the effects of antisperm antibodies. Researchers had couples who tested positive for antisperm antibodies take Tribulus extract and the results of the study showed a 61% increase in conception. An extract of Tribulus terrestris, made into a tablet was given orally to the couples in the study. Men received 1 dose, 3 times a day for 60 days. Women received 1 dose, 3 times a day for 7 days, in the beginning of their cycle (follicular phase), for 6 months. The average time it took for couples to conceive was 5.2 months. This shows that consistency of use is very important!

In addition, TCM and Ayurvedic practitioners have found Tribulus to be very effective in improving sperm count, motility, and morphology when combined with dietary and exercise changes.

Tribulus for Female Fertility

Using Tribulus for Female Fertility and Ovulation Stimulation
In her text Botanical Medicine for Women’s Health, physician, midwife, and herbalist Dr. Aviva Romm shares of one study performed on 36 women who were not ovulating, showed that 67% realized normal ovulation after only 2-3 months of consistent use. The women were given 300-400mg a day, from day 5-14 of their menstrual cycle. 6% became pregnant right away.

A rat study using Tribulus, out of Islamic Azad University in Iran published online in Aug. 2011, showed that Tribulus reduced the number of cysts in the ovaries, in female rats with PCOS. High doses of the extract were administered orally. The treatment showed the ovarian cysts to have significantly decreased, and normal ovarian function was restored. While this was not a human study, it gives scientists more research and knowledge when considering this herb for treatment of PCOS in humans. Many herbalists find that Tribulus is an effective, overall female fertility tonic and ovarian stimulant, making it an excellent choice for women with PCOS. This is especially true for women who are not ovulating due to PCOS.

This herb has been found to be wonderful in aiding women with menstrual irregularities, and improving timing of the entire menstrual cycle. Tribulus is a nourishing tonic for the female reproductive system as a whole, especially concerning the ovaries.

Tribulus combines well with other herbs. See below for herbal combinations…
The following herbs have been shown safe and effective when combined with Tribulus.

  • Lack of libido: Damiana, Maca
  • Male Sexual Dysfunction: Korean Ginseng, Saw Palmetto, Maca or Ashwagandha
  • Female Tonic for Reproductive Health: Shatavari, Maca

Traditional Suggested Dosage of Tribulus terrestris:
Capsules: 500mg a day to start, working up to 1500mg a day as needed.
Liquid Extract (Tincture): 3-5 mL, 2 times a day.

For Men: Tribulus has been shown best to use all month long, for 3-6 months consistently. This is because it takes 46-72 days for an immature sperm to mature before ejaculation.
For Women: In general, Tribulus is fine to take all month long. For women with irregular ovulation timing or anovulatory cycles, Tribulus has been shown best to use from day 5-14 of the menstrual cycle, not past ovulation. Tribulus should not be used during pregnancy.

Safety of Tribulus Use: Pregnancy Caution
Many studies have been conducted using Tribulus. No adverse effects have been reported in humans, even with long-term use, with the exception of gastrointestinal upset in some people after 6 months of consistent use. Despite safety, there have been some reports by Traditional Chinese Medicine practitioners warning that Tribulus should not be used during pregnancy. A woman who is trying to conceive should only use this herb prior to ovulation. Tribulus has been shown to cause or contribute to cholestsis when used during pregnancy. Cholestasis is a liver disease that only happens during pregnancy. In women who develop cholestasis, the normal flow of bile from the gallbladder is affected by very high levels of pregnancy hormones. The gallbladder holds bile produced by the liver, aiding in the breakdown of fats for digestion. Cholestasis slows this function down, which may cause bile acids to spill into the blood stream.

Some animal studies have shown Tribulus to cause the locomotor disorder known as staggers in pregnancy. While another showed decreased survival rate of offspring when taken during pregnancy. This is why Tribulus should not be used in pregnancy. Discontinue use of Tribulus once you find out you are pregnant, or if you think you may be pregnant.

    Hi, I am a PCOS sufferer with mild symptoms . I know that both Tribulus and Black Cohosh can be used as natural alternatives for Ovulation Induction. However I am not quite sure if I can use both of these herbs in one cycle. Could you please inform me whether I can use these two herbs simultaneously for ovulation induction?

    Hi, I suffer from PCOS & am currently dealing with secondary infertility (over 2 years TTC).
    We had success with baby #1 with Vitex + Cramp Bark, however no luck this time. Have added Tribulus & Black Cohosh to the mix and still no luck. We are now looking into a medicated cycle using Clomid. Should I avoid all the herbal supplements while taking Clomid or is there a possibility of any of them working well together?
    Thank you

    Dear Doctor i am using Tribugin from few days but i have one problem. thats big pain in legs and body how i can use and why its giving these kind of problem, dear dr i have sperm count problem but its not working very good what i need

    • Dear Shafqat,

      Do you mean Tribulus? I am not sure what Tribugin is. If you mean Tribulus, I have never heard of its use being associated with leg or any pain in the body. I can’t be sure that is it causing the problem. If you feel it is a cause, then it would be best to discontinue its use and contact your healthcare provider.

      Here is our guide Increasing Low Sperm Count and Improving Male Fertility… for additional tips.

      Dear Elizabeth willett i am proud of your information you are the great one, but tribugin as just like Tribulus, tribulus is sam fromula of tribugin then what i can do further.

    • Hello again Shafqat!

      Tribulus not matter the brand or formulation should not cause leg and back pain. It would be my suggestion to stop using Tribugin. The dietary and lifestyle tips and other suggested herbs, nutritional supplements and natural therapies outlined in that guide I shared last week could be considered.

      If it would helpful to have natural sperm health program created for you, consider working one on one with our fertility herbalist through a Fertility Consultation.

      Take care!

    Hi there, thanks for the helpful information. Just wondering is it possible for tribulus to lose effectiveness if you have been taking it a while? I was having irregular periods after coming off birth control, but taking 500-750mg of tribulus a day gave my regular 34 day cycles for 8 months. Am now trying to conceive but back to having irregular cycles again. Should I increase the dosage or try something else?
    Many thanks in advance!

    • Dear Nicky,

      There are many things that can contribute to irregular menstrual cycles. Changes in stress levels, nutritional levels, hormone balance, exercise routine, weight, etc. can all have an impact on menstrual cycle timing. It has not been my experience that Fertilica Tribulus loses effectiveness. I am inclined to think something else is at play for you given Tribulus supported your cycle until now. It’s hard to know however with just a small picture of what is your overall health. Feel free to contact me here… to share more about your fertility journey and I may be able to guide you further.

      Do reach out to your doctor or pharmacists about side effects and implication use in pregnancy. They are best able to get you these answers. I do not have this information for you.

    Hi! A friend had suggested, after reading a book on hormones and periods, that my ultra-light periods may be related to low estrogen (CD3 testing says it’s at 36, so on the low end). She said the book suggested Tribulus for increasing estrogen, but in reading this article, it looks like (if I’m reading this correctly) that Tribulus also increases FSH which has me concerned because my FSH is already 17. I’m currently taking Vitex and recently added Maca. Would the hormone balancing properties of those two herbs negate the FSH-increasing properties of Tribulus? Should I just skip this herb and look at something else? I’ve seen a few good looking blends with Tribulus and worry about the FSH aspect.

    • Dear Heather,

      Tribulus has been found to increase FSH levels, so it may not be the best herb if it has been determined your FSH level is high. Our Estrogen Fertility Guide shares a variety of ways to nourish the endocrine system with foods, herbs and supplements which may be more beneficial to estrogen balance than working to manipulate and increase low estrogen levels alone. Take time to read through that guide. Fertilica Maca is one well-known, nutrient-packed fertility superfood that nourishes the endocrine system.

      Fertilica Vitex is known to support hormone balance without containing hormones itself, but would not negate the FSH-increasing properties of Tribulus.

    Great website! I’m a 30 to women. low car, very low sugar paleo like diet. Was on BC for 15 years, Have been off birth control for 7 months now. With the help of chaste tree was able to get period back 3 months after cessation of BC. Now for the past 4 months we are trying to conceive. I’m continuing to take chase tree everyday (should I be? now that cycle is normal) and was considering adding tribulus, however I have seen other sites that say take tribulus throughout the month. Why is it suggested to stop before ovulation? Thanks so much fro the help

    • Elizabeth Willett, MA, CH

      Dear Chris,

      You could consider weaning off of Vitex to see if your body is able to maintain balance on its own. Should you conceive while taking Vitex, it is best to wean off of it in early pregnancy.

      Suggested use of Tribulus during the follicular phase of the menstrual cycle is because studies show this is when it is most influential and beneficial, but also because it is not indicated for use in pregnancy. One wouldn’t want to take it after ovulation when trying to conceive because there is a possibility of pregnancy.

      Is this helpful? I do hope so!

    • Avatar

      amazing, thank you for the quick response and yes this makes sense.

      side from the paleo diet, I’m Currently taking a multi vitamin, cod liver oil, symplex F, and chaste tree and tribulus. After reading a bit of your site would you suggest taking maca and tribulus(day 5-14) while either weaning off chaste or continuing to take chaste tree? would symplex F from standard process (a glandular) interfere with any of these herbs?

    • Dear Chris,

      Chaste Tree berry or Vitex is what we consider the #1 Female Fertility Super Herb specific to most menstrual cycle irregularities and hormone balance. Fertilica Vitex can be taken with Fertilica Maca which Fertilica Tribulus, a multivitamin, Fertilica Cod Liver Oil and to my knowledge also with Symplex F.

      Because I am not 100% familiar with Symplex F, if you are concerned, it would be best for you to contact Standard Process to inquire about taking herbs and supplements with this glandular formula.

      Be well!

    I found this article completely by mistake. My husband takes tribulus regularly for strength and I was curious to know if it might have an effect on his fertility. He was tested and everything came back absolutely great. We have been trying for over 2 years with only one PPT which turned into a miscarriage very early on (about 3 weeks). This was a year ago, and since then I’ve had a laparoscopy in August. Most recently told by my doctor that I have a tubal dysfunction that involves scar tissue. I have a 31-day cycle and currently on day 13. I am not entirely sure that I do ovulate, but will use ovulation strips to start checking today. Could tribulus help? Maybe next cycle? Thank you!

    • Elizabeth Willett, MA, CH

      Hello Kate!

      To sum it up, Tribulus may be supportive of both men and women in terms of supporting healthy libido, promoting normal hormone levels and even supporting healthy immune system function.

      Specific to female reproductive health, Tribulus may encourage normal monthly ovulation in women. Specific to male reproductive system health, Tribulus may encourage normal sperm count and motility, aid in normal sperm production and encourage normal sexual function. I can not say for sure if Tribulus is a reason why your husbands tests came back great, but the potential is there that this herb supported his fertility health.

      Consider also learning more about naturally supporting fallopian health and function as you educate yourself.

      I hope this is helpful!

    Hi! We’ve been trying to get pregnant for 3 years. My doctor wants me to see a fertility specialist because she says that my husband has a low sperm count. My husband’s doctor disagrees with my doctor and says the sperm count is fine and to just “give it time.” So we are going to try the natural route for a few more months then see a specialist if needed. My husband and I are currently taking multi-vitamins and Maca, and I am adding folic acid to that. Is it safe for both of us to add Cod Live Oil and Tribulus? Thanks!

    Hi Darlene,

    I have elevated levels of antisperm antibodies and I would like to know if I should also drink the Tribulus from day 5 to 14? My cycle varies between 28 and 32 days so I could also benefit from a more stable cycle.

    • Elizabeth Willett, MA, CH

      Dear Stephany,

      Yes, Tribulus is best used from day 5-14 of the cycle, not past ovulation, no matter the fertility issue.

      You might also consider learning about Systemic Enzyme Therapy. Systemic enzyme blends work to stabilize and promote proper function of the immune system. This may greatly help the person who has developed antisperm antibodies to help suppress an attack on sperm, while also working to prevent long term damage to the health of the sperm, and in women, may also reduce pain and inflammation cause from allergic reaction to the semen.

    Hi Dalene,

    I want to start taken this but i have some…i guess concern. I have hypothyroidism and I’m taken 150mcg of levothyroxine. I guess my concern would be if i took this herb will it interact with my thyroid medication? my numbers have been stable since 2012 so that isn’t an issue anymore. I want to take this herb to help me ovulate and get my periods back on track without taking provera anymore. I would also like to take vitex as well but again my concern is will any of this interact with my medications (if unaware what hypothyroidism is, it is when you thyroid glad in your throat doesn’t give off enough hormones and you gain weight and some other stuff)

    • Elizabeth Willett, MA, CH

      Hello Krystal!

      I hope you don’t mind if I offer some guidance.

      Thyroid function influences reproductive hormone balance, but reproductive hormones also influence thyroid function. Any time you wish to take herbs that have an affect on hormone balance as both Tribulus and Vitex do, it is best to talk to your doctor about the possibility of adding them to your natural health plan. If you already take medications and are wondering if any of these supplements are safe for use with your medication, please speak with your doctor first, prior to using them.

      Be well!

    Hi Dalene.
    I started tribulus 7 weeks ago in the form of pregnancy prep, 2 pills 2x a day. I also supplement with vitex to bring the total close to 1000 mg as you suggested for my annovulation problem with all other negative tests by an RE. I also added saw palmetto as you suggested for my hirsutism. How long can it take to bring on ovulation? I haven’t had a period since April 7th so I started this mid June to get a cycle going. Previously to April 500 mg of vitex had brought on a 65 day, a 50 day, and then a 39 day cycle over 5 months, and then stopped. This was better than the nothing I had for 6 months prior to vitex. Is accupuncture helpful too?

    • Hi Michelle,

      It is extremely difficult to guide you without knowing more about your health and lifestyle. You said that all tests performed by your RE came back all negative, but I am not sure what testing you had done. If we have corresponded before via comments on another article and that is what you are referring to, I am sorry, but we receive so many comments, it is too difficult for me to remember every person’s story. Based on the information you have provided here, I would say give it some more time, as you know, herbs need to be taken for many months, consistently, as directed for benefits to be achieved. If you desire more personal guidance, I urge you to consider working with one of our fabulous and very knowledgeable herbalists through our Fertility Consultation program. Our fertility consultations provide you with detailed guidance based on your specific needs.

      Acupuncture is always beneficial to any health issue, in my opinion. Many acupuncturists will want you to be on their own personal herbal protocol, in that case, we don’t recommend combining the herbs you are taking with Chinese herbal formulas. It is best to stick to one herbal program at a time.

      Best Wishes!

    I have been off of birth control pills for 3 months now and I have been bleeding off and on (some period like bleeding) since day 12 of my cycle. I’m wondering if these irregularities are from the birth control. My periods were regular before and I have one child already. We are ttc but I’m worried it may take a long time. Will tribulus help? Where could it possibly be purchased? Thanks for any help!

    • Elizabeth Willett, MA, CH

      Hello Jessica!
      When it comes to hormones and their proper function, it is a delicate balancing act. Prolonged use of fertility medications, one of which is birth control (bc), can be confusing to the body. Any time between when you stop using it and up to a year afterward is considered a normal time frame in which it will take your body, on it’s own, to regulate your hormones and start a regular menstrual cycle. For some this simply take longer. It is going to take time for your body to remember how to or be supported in having normal hormonal balance.

      Without knowing in more detail your diet and lifestyle, it sounds as though your body may still be detoxifying from this bc use in addition to that your hormones may still be a bit out of balance post discontinuing bc use.

      Tribulus may be supportive if you know you are not ovulating and you are struggling to get your cycle back. Tribulus can be purchased here….

      What might be more helpful however is to learn about all of the ways you can support your body in recovering from bc use which. I think you’ll find reading How to Balance Your Hormones After Birth Control“> to be helpful!

      We are also happy to support you by creating a personalized program based on your specific fertility needs through a Natural Fertility Consultation.

    My doctor diagnosed me with pcos in May due to irregular periods and slightly elevated testosterone levels after coming off BCP last year. My cycle was normal for about 6 months and then I started getting a period every three months. I decided to try using tribulus to help me ovulate on a monthly basis. I took it in May and again in June as your website directs (cd 5-14) and have successfully ovulated both months. Should I continue to take the tribulus or see if my body is able to maintain a regular menstrual cycle on its own? I have been taking vitex since February and plan to continue on it for a full year.

    • Hi Mary,

      Thank you for sharing your story! Tribulus is best taken for at least 3-6 cycles consistently, to achieve best results. I find that women with PCOS often need a longer period of time to help the body regulate hormones and the menstrual cycle, around 8 months of consistent use of this herb. Tribulus is fine to combine with Vitex.

      Best Wishes!

    Also, I (34) ovulate on my own but it varies from cd13-17. I would like to try to ovulate closer to cd13 on a regular basis. Would taking tribulus help with this, or should I just leave well enough alone in that department.

      For Women: Has been shown best to use from day 5-14 of the cycle, not past ovulation or during pregnancy.

      Best used for 3-6 months, but may be used longer if needed. Most women begin to ovulate within the first 2-3 cycles of use.

      Tribulus is best taken prior to ovulation in the cycle, from days 5-14 (approximate). Vitex agnus-castus is best taken all month long, except during menstruation. Both Tribulus and Vitex have been shown safe to use at the same time.

    Hi Darlene,
    I found out earlier this year that had PCOS. My Dr. told me that I wasn’t ovulating and prescribed me birth control pills to aid in ovulating. I really don’t want to take birth control because there are just too many side effects. I’ve done research on various natural things I can take to promote ovulation. I am currently taking Vitex and Maca Root capsules (just started a week ago). I also ordered some pradrantak churna. Is it ok to take the three of these together? If not, what would you suggest I take? Also is Tribulus ok to take with the other herbs?

    My Dr. really didn’t give me much information on PCOS. So I’ve been doing research on PCOS and also trying to get my cycles and ovulation back on track. I had normal cycles up until about 3 months ago. Now I spot for 3-4 days only. I’m not looking to conceive right now, but I plan to within the next year or so and I want my body to be prepared.
    Please Help!!!! I am open to any suggestions.

    • Hi Mesha,

      I am not familiar with the herbs in Pradrantak churna, as this is an Ayurvedic formulation and I am a western herbalist. I am not sure that it would be good to mix vitex with this. It is usually best to start off with only 1-2 herbs and see how your body reacts and responds to them. Tribulus has been shown safe to combine with vitex and maca. Diet changes are going to have the greatest impact on PCOS. There is no “cure” for PCOS, this is a syndrome that needs to be managed long-term.

    Hi Dalene
    I am 44 yrs old and am seeking another pregnancy. My FSH level is 10.0, Estradiol and LH are in normal range.
    I don’t have pcos problems and my uterus is healthy. Recently I found out that I have an Insulin resistance problem which may inhibit ovulation.
    My husband has a low sperm count but not the lowest – motility is fine – antibodies to sperm seem ok too. He’s been taking Tribulus for the last 6 months but in low dosage 500mg a day.
    I’ve been taking Agnus castus 400mg per day for the last 3 months to help ovulation and gymnema sylvestre 500mg per day for the Insulin resistant problem.

    I would like to combine Tribulus to these but would like to know what is the correct times to take Agnus castus in a month in combination with Tribulus which is from day 5 – 14.
    Many thanks

    I ordered 625mg of Tribulus Terrestris Extract is this the same as the Fertillica? Also I have been taking Fertibella is Tribulus safe to take with this?

    • Hi Kimberly,

      Because there are so many different FertiBella products I cannot say if Tribulus is safe to combine with them or not. Please contact that company to ask if it is safe. Tribulus Terrestris extract is a liquid extract of the herb, our Fertilica Tribulus is a capsule of dried herb.

      All the best,

    Hi Dalene

    I understand maca and vitex complement each other and tribulus can be combined with maca. However I would like to know if I can take vitex and tribulus together? I am taking maca everyday (with breakfast) and I am planning to resume taking vitex once my period is over (taken first thing in the morning) but now I would also like to also start taking tribulus from Day 5 until ovulation. Will all the herbs complement one another?
    Must tribulus be taken only after my period is over and discontinuing after ovulation or should I aim to start taking from Day 5 regardless of whether bleeding has completely stopped or not?

    • Hi Monica,

      Tribulus has been found to combine well with other herbs for fertility, including Vitex and Maca. Tribulus is best taken from after the period ends, up to ovulation. If you have long drawn-out cycles with scant bleeding at the end, Tribulus may be taken for those days of spotting at the end of the cycle.

    Hi can I take tribulus and L-Arginine together? Is it safe? Arginine increases my sperm count but can I combine it with Tribulus?

    hi I was just wondering more about tribulus. I did buy some for my Husband and I to take and I’ve also heard u take from cd5- ovulation. is this true? also what is the best dosage to take? I can’t really find much info that I need on this online so I thought I would ask u. also does my husband just take it everyday? and if I follow the directions on the bottle and take 1 500mg pill 1 to 3 times a day is that good for me to help promote natural ovulation?

    • Hi Mandi,

      For both men and women our Fertilica Tribulus herbal dietary supplement suggested usage is 1 capsule 1-3 times daily as needed prior to meals. Starting at the lowest dosage and working up as needed; listen to your body. Men may need to start at a higher dosage because they weigh more. If you are trying to conceive it is best to use prior to ovulation, in case of pregnancy.

    My husband and I were reading about vitamins/herbs he could take to improve his sperm mobility and he thought that Tribulus, L-Carnitine and CoQ10 sounded good. Can all of these be taken together? We saw that they are included together in the Male Fertility Cleanse, but would like to buy them separately. If so, what dosage would you recommend…the general dosage on the bottle stated for each?

    Thank you.

    • Hi Rachel,

      Yes, all of those have been shown safe to combine. Please follow the recommended dosage on the bottle.

    I just hade my FSH levels tested and it came back at 18 (was 55 last July)
    just wondering if I can use tribulus? My acpuncturist said to take 2 capsules per day from cd 5 to ovulation.
    I’m a little concerned as from what I’ve read tribulus increases FSH???

    • Hi Debbie,

      Tribulus may increase serum FSH in some women, but not all, so you may want to reconsider. I think it is good that you are working with your acupuncturist and it is better to work closely with a practitioner that can monitor your progress and adjust accordingly, that is a much higher quality of care as opposed to advice from the internet. An practitioner like your acupuncturist knows your health history, I don’t.
