Can Fenugreek Cure Erectile Dysfunction And Increase Libido?

Yes, Fenugreek can help you overcome erectile dysfunction. And it can also increase your libido. It may even make your orgasms more intense.


Research has demonstrated that Fenugreek can increase your testosterone production. More testosterone will normally increase your libido and make it easier for you to get erections. And it may even amplify sexual sensations.

Scientific research has also concluded that Fenugreek can increase nitric oxide production. More nitric oxide will normally enable you to get erections faster and easier.

In addition, Fenugreek can reduce blood glucose and increase insulin sensitivity. Both are likely to improve bloodflow, which in turn may help erectile dysfunction.

Let’s learn more about Fenugreek.

Fenugreek can help overcome erectile dysfunction

Fenugreek (Trigonella Foenum-Graecum)

Fenugreek is also known as Greek Hay Seed, Menthi and Bird’s Foot. It has been used in the Mediterranean, the Middle East and Asia, as a food and medicine for more than 6,000 years. 

It was particularly held in high regard for its medicinal and culinary properties among the Egyptians, Greeks and Romans. 

Medicinally, the plant has traditionally been used to cure digestive problems, diabetes, wounds, inflammation, kidney problems, aiding women with breastfeeding, and improving sexual functions. 

In addition, it is widely used as a spice to give flavors to foods. 

Fenugreek is an annual plant, meaning it completes its life cycle from germination to seed in one year.

Fenugreek has been used as a food and medicine for more than 6,000 years

It is an erect herb, growing to between 20 and 50 cm. It has leaflets with three leaves and small white or yellow flowers. Its seed pods contain ten to twenty small, flat, yellow-brown and pungent seeds. 

Fenugreek is believed to have originated in the western Mediterranean, but is today cultivated all over the world. 

Both the leaves and the seeds are common ingredients in many cuisines of the Middle East, Africa, Asia, and particularly in India. 

The part of the plant that are most commonly used for sexual health benefits, are the seeds. 

How Does Fenugreek Enhance Sexual Functions?

Research studies have demonstrated that Fenugreek has the ability to both reduce the prevalence of erectile dysfunction, and to increase sex drive.

How Does Fenugreek Enhance Sexual Functions?

It does this primarily through the following pathways:

  • Increasing testosterone production
  • Increasing nitric oxide production
  • Reducing blood glucose and increase insulin sensitivity

Fenugreek Can Increase Testosterone Production

First of all, why is testosterone important?

Testosterone is the key to your sexual functions. It is the primary male sex hormone, and its job is to control and support anything sexual that happens in your body.

With lots of testosterone, your sexual abilities (all else equal) will normally work well.

With little testosterone, you will probably struggle sexually.

Testosterone is the key to your sexual functions

The seeds of Fenugreek contain something called steroidal saponins. And according to research (see below), these can have powerful effects on testosterone production. 

Three of the most important of these saponins are called protodioscin, diosgenin and dioscin. 

By the way, these are the same components that are found in Tribulus Terrestris. In fact, Tribulus Terrestris and Fenugreek are believed to have very similar effects on testosterone. 

Fenugreek is believed to increase testosterone levels via three key pathways:

  • By protodioscin being a precursor to dehydroepiandrosterone (DHEA), which is in turn a precursor to testosterone 
  • By protodioscin stimulating the production of luteinizing hormone, which in turn can lead to increased testosterone production
  • By inhibiting aromatase and 5-a reductase, which in turn preserve existing testosterone
Fenugreek Can Increase Testosterone Production

Protodioscin Can Be A Precursor To Dehydroepiandrosterone (DHEA)

Protodioscin has in research studies been reported to be a precursor to dehydroepiandrosterone (DHEA). This means that DHEA can be created from protodioscin.

However, this was found in studies on the protodioscin found in Tribulus Terrestris, not in Fenugreek. I am not aware of similar findings of protodioscin in Fenugreek in regards to DHEA.

DHEA functions as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids. This means that DHEA is a precursor to testosterone.

In other words, your body can create testosterone from DHEA.

To summarize: Protodioscin can increase DHEA production, which in turn can increase testosterone production.

Protodioscin Can Be A Precursor To Dehydroepiandrosterone (DHEA)

Protodioscin Can Stimulate The Production Of Luteinizing Hormone

Research has demonstrated that Fenugreek can stimulate the production of a hormone called luteinizing hormone (see below for research study). 

This hormone is essential for your testosterone manufacturing.

Testosterone is produced by cells called leydig cells that sit in your testes. And it is luteinizing hormone that instructs the leydig cells to produce this testosterone. 

More luteinizing hormone will normally mean higher testosterone production. 

Therefore, if Fenugreek is able to increase the amount of luteinizing hormone, this should also lead to an increase in testosterone production.

Protodioscin Can Stimulate The Production Of Luteinizing Hormone

Fenugreek Can Inhibit Aromatase And 5-a Reductase

Research studies (see below) have also reported that Fenugreek inhibits something called aromatase and 5-a reductase.

Aromatase is an enzyme that converts testosterone to estrogen. 

5-a reductase is an enzyme that converts testosterone into dihydrotestosterone. 


When Fenugreek inhibits or stops these enzymes from doing their job, they will stop or slow down the conversion of testosterone into other compounds. 

As a result, your testosterone level should go up.

Fenugreek Can Inhibit Aromatase And 5-a Reductase

Fenugreek Can Increase Your Nitric Oxide Production

Why is nitric oxide important?

You need healthy nitric oxide production in order to get an erection.

When your penis is flaccid, the blood vessels inside you penis are essentially closed up. Nitric oxide has the ability to open and expand these blood vessels. 

Therefore, nitric oxide is the key to the lock that opens the flow of blood to your penis.

Without sufficient nitric oxide, you will find it almost impossible to get and maintain an erection.

Research (see below) has demonstrated that Fenugreek extract can improve nitric oxide production in the endothelial cells. 

Proper Bloodflow To Avoid Erectile Dysfunction

It is believed that this occurs via protodioscin’s ability to make the enzyme nitric oxide synthase more efficient at producing nitric oxide. 

This finding is supported by studies on the effects of the protodioscin found in Tribulus Terrestris, more so than from studies on Fenugreek.

Fenugreek Can Reduce Blood Glucose And Increase Insulin Sensitivity

Fenugreek seeds are high in soluble fibre. When fibre is consumed with carbohydrates, this causes a slow and steady rise in blood sugar, instead of spike. 

In other words, Fenugreek slows down the digestion and absorption of carbohydrates. 

Actually, research has found that this can help manage diabetes type 1 and 2.

Research (see below for study) has also found that Fenugreek can reduce blood glucose levels, improve glucose tolerance, lower ‘bad’ cholesterol, and reduce triglycerides.

Diabetes and insulin

Studies have found that the amino acid 4-OH Ile in fenugreek seeds, increases glucose-induced insulin release. 

And also that fenugreek can make insulin receptors more efficient at communicating with insulin.

With more insulin and with more effective insulin, your cells are able to absorb more glucose.

Which means more glucose is removed from your blood. This can have several positive effects on your bloodflow:

  • Your blood gets thinner and flows more smoothly through your blood vessels
  • Atherosclerosis formation is less likely
  • You are likely to produce less superoxide (free radical) which can deplete your nitric oxide   

All of the above will normally make it easier to get and maintain erections.

Scientific Studies On Fenugreek’s Impact On Libido And Erectile Dysfunction

I want to provide you with all the relevant scientific evidence that exists about Fenugreek and its impact on sexual functions. 

Or at least, all the relevant scientific evidence that I am aware of. 😊

This way, you can read these studies and better draw your own conclusions. 

Therefore, in this section you find a summary of the key findings from these scientific studies. And you find a link to the studies, should you want to read the actual studies. 

I have presented all relevant studies I am aware of, whether they indicated that the effect from Fenugreek was positive or negative.

Scientific Studies On Fenugreek’s Impact On Libido And Erectile Dysfunction

Fenugreek Study 6: June 2016

Beneficial effects of fenugreek glycoside supplementation in male subjects during resistance training: A randomized controlled pilot study.

The aim of this study was to evaluate the efficacy and safety of the glycoside fraction of fenugreek seeds on physiological parameters related to muscle anabolism, androgenic hormones, and body fat in healthy male subjects.

This supplement contained 600mg of Fenugreek extract, or a placebo, which was taken daily for 8 weeks.

The study was done on 60 healthy male volunteers, aged 18-35, who went through a supervised 4-day per week resistance-training program.

The outcome?

The study showed that the subjects in the Testofen group had a 99% increase in free testosterone levels vs. a 49% increase in the placebo group, over 8 weeks. 

There was little difference in total testosterone between the two groups.

The study also indicated that the Testofen group had a decrease in body fat.

It was indicated that it may be the glycosides and saponins in Fenugreek that produced these effects.

Please note that this study was done by Gencor, the manufacturer of the supplement, and hence there may be a conflict of interest regarding the outcome of the study.

Fenugreek can impact muscle anabolism, androgenic hormones, and body fat

Fenugreek Study 7: June 2016

Fenugreek Study 8: October 2015

Efficacy of a Novel Fenugreek Seed Extract (Trigonella foenum-graecum, Furocyst) in Polycystic Ovary Syndrome (PCOS).

This study was done on women.

The purpose of the study was to to determine the efficacy of a Fenugreek seed extract called Furocyst (containing 40% furostanolic saponins), on the reduction of ovarian volume and the number of ovarian cysts in premenopausal women.

The study was done on 50 premenopausal women aged 18-45 years, diagnosed with Polycystic ovary syndrome.

The women were given 1 gram of the Fenugreek extract per day, or a placebo, for 90 days.

The outcome?

46% of the participants showed reduction in cyst size, while 36% of subjects showed complete dissolution of cyst. 71% of subjects reported the return of regular menstrual cycle on completion of the treatment, and 12% of subjects subsequently became pregnant.

But more interesting for our purposes: The participants experienced a significant increases in luteinizing hormone. This is a precursor to testosterone, and can therefore help increase testosterone production.

Fenugreek can increase luteinizing hormone

Fenugreek Study 9: September 2011

Physiological aspects of male libido enhanced by standardized Trigonella foenum-graecum extract and mineral formulation.

The goal of this study was to review the effects on male libido from a supplement called Testofen. 

This supplement contained 560 mg Fenugreek, 17 mg magnesium, 15 mg zinc and 5 mg vitamin B6.

It was taken daily for 6 weeks. 

The study was performed on 60 healthy men, aged 25-52, with no signs of erectile dysfunction. 

The outcome:

82% of the participants reported improvements in libido, 67% reported improvements in sexual recovery time and 63% reported improvements in quality of sexual performance. 

However, the study found no significant increase in testosterone levels.

It should be noted that the ingredients administered other than Fenugreek (magnesium, zinc and vitamin B6) are the components of ZMA. This is another powerful supplement that by itself has demonstrated sexual effects.. 

It is therefore possible that these 3 ingredients, or all the ingredients together, may have produced the positive sexual effects.

Improvements in libido from Fenugreek

Fenugreek Study 10: October 2010

Effect of furostanol glycosides from Trigonella foenum-graecum on the reproductive system of male albino rats.

The objective of this study was to study the anabolic and androgenic activity of the furostanol glycosides fraction of Fenugreek in immature castrated male Wistar rats.

The rats were treated with either testosterone (10 mg/kg bi-weekly), or Fenugreek (10 and 35 mg/kg) once daily for 4 weeks.

The outcome?

There was no change in the testosterone level in the rats. However the study found that the weight of the levator ani muscle increased. 

The levator ani is the main pelvic floor muscle and is important to getting and maintaining erections.

Androgenic activity of Fenugreek

Fenugreek Study 11: October 2010

The effects of a commercially available botanical supplement on strength, body composition, power output, and hormonal profiles in resistance-trained males.

The purpose of this study was to evaluate the effects of Fenugreek supplementation on strength and body composition.

This supplement contained 500mg of Fenugreek extract, or a placebo, which was taken daily for 8 weeks.

49 men participated in a supervised 4-day per week periodized resistance-training program.

The outcome?

Fenugreek extraction had a significant impact on both upper- and lower-body strength, and body composition, in comparison to placebo.

The study found no major difference in testosterone levels.

Fenugreek's effect on resistance-trained males

Fenugreek Study 12: December 2010

Effects of a purported aromatase and 5α-reductase inhibitor on hormone profiles in college-age men.

The purpose of this study was to determine the effects of Fenugreek, an alleged aromatase and 5-α reductase inhibitor, on strength, body composition, and hormonal profiles in resistance-trained men.

This supplement contained 500mg of Fenugreek extract, or a placebo, which was taken daily for 8 weeks.

Aromatase is an enzyme responsible for a key step in the synthesis of estrogens. Aromatase also converts testosterone to estrogen. 

5-a reductase is an enzyme that converts testosterone into dihydrotestosterone. 

By inhibiting these enzymes, the theory is that Fenugreek should make testosterone levels go up. 

The outcome?

After 8 weeks, the men had an average increase in total testosterone of 7%, and an increase in free testosterone of 12%. 

The study concluded that 500 mg of daily supplementation of this Fenugreek extract demonstrated that Fenugreek was only able to inhibit aromatase and 5-a reductase activity to some extent, but not completely.

The study also concluded that Fenugreek was able to reduce overall body fat.

Fenugreek Study 13: May 2009

Fenugreek Extract Supplementation Has No effect on the Hormonal Profile of Resitance-Trained Males.

The aim of this study was to investigate the potential anabolic effects of fenugreek extract supplementation in conjunction with a controlled resistance training program.

This supplement contained 500mg of Fenugreek extract, or a placebo, which was taken daily for 8 weeks.

The study was performed on 45 resistance trained males, going through a training program.

After 8 weeks, the study concluded that the supplement did not appear to affect hormonal status in resistance trained males.

Other Potential Benefits From Fenugreek

Fenugreek has also been claimed to have the ability to increase estrogen, in estrogen deficient persons. 

It has also been used to increase muscle mass and improve athletic performance. 

Fenugreek is also used for digestive problems, upset stomach, constipation, kidney ailments, inflammation of the stomach (gastritis), atherosclerosis, high blood pressure, to reduce cholesterol and triglyceride levels, mouth ulcers, bronchitis, tuberculosis, chronic coughs, certain cancers, arthritis, asthma, sore throat, fevers and skin irritations. 

It has also been reported to increase volume of breast milk in mothers. 

Lastly, some people have also commented that Fenugreek may cause body secretions, including urine, to smell like maple syrup. 😊

Let me tell you about my experience with Fenugreek.

Potential Benefits From Fenugreek

My Experience With Fenugreek Supplements

  • Form: At least 40% saponins extract in powder form
  • Dose: One tablespoon (not fully topped) (approximately 7 grams)
  • When: 60-120 minutes before sex
  • Effect on libido: OK
  • Effect on erection: Good
  • Effect on sensation: Good
  • Taste: OK
  • Verdict: A nice supplement
  • Noticed side-effects: None

In my research on supplements, I read several articles about which supplements supposedly worked. Fenugreek had popped up again and again, and it was therefore a supplement I was keen to try.

Pure Fenugreek Powder

I therefore started reading up on Fenugreek to understand it better. I learned that there supposedly was no common side-effects and low probability of toxins. 

The pathways in which it was supposed to work, seemed plausible. Also, the alleged effects it was supposed to have, seemed good. 

After I was comfortable giving it a go, I bought a Fenugreek supplement in powder form, extracted to 50% saponins. 

By the way, when I buy supplements, I normally always buy them in powder form.


Supplements in powder form are normally fresher (newer), purer and of better quality.

Fenugreek supplement in powder form

I also made sure that the supplement had a reliably looking certificate that stated that the supplement was pure. Meaning that it contained no heavy metals and toxins, or at least well below internationally recommended limits. 

So I mixed one tablespoon of the Fenugreek powder (about 7 grams) with cold water. I stirred until the powder had dissolved, and then drank it. 

I did this about 90 minutes before sex. 

Many supplements have a horrible taste. But to me, the taste of Fenugreek was pretty mild.

And what were the effects? 

For me, the effects from Fenugreek were good. I would not say amazing, but definitely good. 

Fenugreek seeds in wooden spoon

By the way, I have since taken Fenugreek on many occasions, and the effects I have obtained have been relatively consistent.

Fenugreek has provided me with three effects. 

The first effect is that Fenugreek normally makes me slightly hornier. I often start to think more about sex and I can feel ‘I am getting ready. This normally happens about an hour after I take it.

The second effect, is that my erections become significantly firmer and harder. I also normally get erections faster and easier. In addition, my erections last pretty much for as long as I want. 

The last effect from Fenugreek is that it makes the pleasurable sensations from sex even better. Fenugreek takes sex to another level, by amplyfying the intensity of the sensations.

Fenugreek makes erections firmer and harder

Although Fenugreek is great on its own, the effects are even more intense when I combine it with other supplements, such as L-arginine, Pine bark and ZMA

I normally always take supplements in combinations. And the following combination has worked super well for me:

  • Fenugreek (7 grams)
  • L-arginine (7 grams)
  • Pine bark  (7 grams)
  • ZMA (0.5 grams)

Safety Of Fenugreek

Is it safe to take Fenugreek in the doses that I have taken? Which is about 7 grams.

purchase a high quality version of Fenugreek here

The answer is that I don’t know. 

I am not a doctor and I don’t know for sure whether this is indeed safe.

However, in some of the research studies above, the participants noticed no material side effect from taking relatively large doses of the supplements.

That said, I have not seen enough studies regarding the safety of this supplement.

Personally, I have never experienced any side effects from taking Fenugreek in these doses. 

I have taken it on multiple occasions over several years, and not a single time have I experienced negative side effects.

Safety Of Fenugreek

However, that does not mean that it is safe. 

There is also a chance that your body may react differently than my body, to the supplement. 

Should you want to try the same dose of this supplement as I take, you do it 100% at your own risk.
