Shilajit and Sexual Health: Testosterone, Fertility & ED (2026)

Does shilajit help with sexual health in men?

The evidence is indirect. No clinical trial has tested shilajit for erectile dysfunction or sexual performance as its primary outcome. What exists are two trials measuring testosterone and sperm quality, both of which are relevant to male sexual health but neither of which directly measured sexual function, libido, or erectile performance.

The testosterone trial. Pandit et al. (2016) enrolled 96 healthy men aged 45 to 55 in a randomized, double-blind, placebo-controlled study. At 500 mg/day for 90 days, total testosterone rose approximately 20% and free testosterone about 19% compared to placebo. DHEAS (a precursor to testosterone) also increased. Gonadotropin levels (LH and FSH) remained stable, suggesting the effect occurred upstream of the pituitary (Andrologia, PubMed).

Testosterone is one driver of male sexual function, so a 20% increase in men with suboptimal levels could translate to improved libido, mood, and energy. But the study did not measure these outcomes, and a 20% increase within the normal range is modest. It does not turn shilajit into a hormone therapy or make it comparable to testosterone replacement.

The fertility trial. Biswas et al. (2010) treated 28 oligospermic men with 200 mg/day for 90 days. Total sperm count increased 61.4%, motility improved 37.6%, and serum testosterone rose 23.5% (Andrologia, PubMed). For men dealing with subfertility, this is directly relevant. For general sexual health, it confirms that shilajit interacts with the reproductive hormonal axis, but the sample was small (28 men) and the design lacked a placebo arm.

Fertility: what the sperm data means practically

The Biswas 2010 fertility trial is significant because it is the only shilajit study that directly measured reproductive outcomes rather than hormonal markers alone.

A 61% increase in total sperm count sounds dramatic, but context is essential. The 28 men in the study had oligospermia, meaning clinically low sperm counts (below 20 million per milliliter). The improvement moved their counts toward the normal range, which is meaningful for men actively trying to conceive. For men with normal sperm counts, this trial says nothing about further improvement, since they were not studied.

The motility data is equally relevant: a 37% increase in motile sperm means more sperm are capable of reaching and fertilizing an egg. Combined with the count increase, these are the parameters a fertility specialist (reproductive endocrinologist) would care about when evaluating whether a supplement is worth trying as part of a broader fertility protocol.

The limits remain real. Twenty-eight men is a tiny sample. The study used a treated-versus-untreated design rather than a true placebo control. No independent group has replicated these findings. For couples dealing with subfertility, the data is a conversation starter with a fertility specialist, not a guarantee. The specialist can put it in context alongside semen analysis results, partner factors, and other interventions with stronger evidence.

For dosing protocol that matches this trial (200 mg/day for 90 days), see how much shilajit to take. For what the evidence looks like across all claims, see the evidence on shilajit.

Does shilajit help with sexual health in women?

One well-designed trial directly measured female sexual function and found a significant positive effect.

Mosavi et al. (2023) conducted a triple-blind, placebo-controlled RCT with 48 reproductive-aged women. The intervention group received 200 mg of shilajit twice daily for 60 days. Using the validated Female Sexual Function Index (FSFI), the shilajit group scored 28.93 at day 90 versus 22.09 in the placebo group (p<0.001). Improvements showed in desire, arousal, lubrication, and satisfaction. The domains of orgasm and pain did not change. No adverse effects were reported (Traditional Medicine Research, DOI).

This is the most directly relevant study for the question "does shilajit help with sexual function?" because it actually measured sexual function as its primary outcome, unlike the men's trials which measured testosterone and sperm. The limits are the small sample (43 completed), a single study from a single group, and publication in a non-PubMed-indexed journal. But the FSFI is a validated instrument, and the effect size is clinically meaningful. For the full breakdown of women-specific evidence, see shilajit benefits for women.

Does shilajit work like Viagra?

No. They operate through completely different mechanisms, on completely different timescales, with completely different levels of evidence.

Sildenafil (Viagra) is a PDE5 inhibitor: it blocks the enzyme that breaks down cyclic GMP in the smooth muscle of penile blood vessels, allowing more blood flow in response to sexual arousal. It works within 30 to 60 minutes of a single dose. It has been tested in dozens of large, rigorous clinical trials across thousands of patients. It is a pharmaceutical drug approved by the FDA for erectile dysfunction.

Shilajit is a mineral-rich natural supplement. Its proposed mechanism for sexual health is indirect: fulvic acid may support nitric oxide bioavailability (which is upstream of the pathway Viagra acts on), and the testosterone effect may improve libido over weeks. It takes 8 to 12 weeks of daily use before any effect is expected. It has been tested in a handful of small trials that did not measure erectile function directly. It is a dietary supplement, not an FDA-approved drug, and calling it "natural Viagra" is both inaccurate and irresponsible.

If you have persistent erectile difficulty, see a urologist. The causes often include vascular disease, medication side effects, or psychological factors that no supplement can address. Shilajit is a long-term general wellness supplement, not an acute sexual performance product.

Does shilajit increase size?

No. There is zero evidence, from any source, clinical or otherwise, that shilajit increases penis size. This claim is pure marketing fiction with no basis in physiology or research.

Penis size is determined by genetics and developmental factors during puberty. No supplement, including shilajit, has been shown to change penile anatomy in adults. Products marketed with size claims are exploiting insecurity for sales. Do not buy any supplement on the basis of size claims.

How does shilajit theoretically support sexual function?

The proposed mechanism rests on three pillars: testosterone support, antioxidant protection of nitric oxide, and mitochondrial energy production. All three are plausible based on the available research, but none has been directly proven to improve sexual performance in a clinical trial.

Testosterone. The Pandit 2016 trial demonstrated that shilajit can modestly raise testosterone in middle-aged men with suboptimal levels. Testosterone influences libido, arousal, mood, and energy, all of which contribute to sexual health. But supplemental testosterone support is not the same as treating hypogonadism, and the effect size is modest.

Nitric oxide. Fulvic acid is a potent antioxidant that may reduce oxidative degradation of nitric oxide, the molecule that signals blood vessels to relax. Better NO bioavailability supports better blood flow, which is relevant to both male erectile function and female arousal. This mechanism is documented in the broader fulvic acid literature (Carrasco-Gallardo et al., 2012, PubMed), but no trial has measured NO levels in the context of shilajit and sexual function specifically. For what fulvic acid is and how it works in the body, see what is shilajit.

Mitochondrial energy. Dibenzo-alpha-pyrones in shilajit may support cellular ATP production by stabilizing Coenzyme Q10. Reproductive cells, especially sperm, are heavily energy-dependent (Stohs et al., 2014, PubMed). This is consistent with the improved sperm motility seen in the Biswas trial. Whether this translates to perceptible improvements in sexual energy or stamina has not been tested.

What to expect: a realistic timeline

Shilajit is not a performance product. It is a long-term supplement whose effects on sexual health markers emerge over weeks to months of consistent daily use.

Weeks 1 to 4. No measurable change expected. The Biswas fertility trial found initial hormonal shifts beginning around this window, but they were not clinically significant yet. If you feel different during this period, it is likely placebo or unrelated lifestyle factors.

Weeks 4 to 8. In the Pandit testosterone trial, measurable hormone changes were documented by the midpoint assessment. If shilajit is going to work for you, subtle shifts in energy, libido, or mood may begin to appear during this phase. These are not dramatic and should not be confused with a pharmaceutical response.

Weeks 8 to 12. All three key trials (Pandit testosterone, Biswas fertility, Mosavi female sexual function) completed their assessments at or around this window. This is the minimum commitment for a fair evaluation of whether shilajit is producing any effect for you personally.

Beyond 12 weeks. The Pingali bone density trial ran 48 weeks, suggesting that some effects may continue to develop over longer periods. For sexual health specifically, consistent daily use at 200 to 500 mg is the protocol that aligns with the trial data.

What else affects sexual health (and what supplements cannot fix)

Sexual health is multifactorial. Supplements are one input among many, and rarely the most important one.

Sleep. Testosterone production is heavily linked to sleep quality. Men who consistently sleep fewer than 6 hours show reduced testosterone and poorer sexual function. No supplement compensates for chronic sleep deprivation.

Exercise. Resistance training is one of the most reliable natural testosterone boosters. Regular exercise also improves cardiovascular function, blood flow, and mood, all of which directly affect sexual health.

Stress and mental health. Cortisol (the stress hormone) suppresses testosterone production. Chronic stress, anxiety, and depression are among the most common causes of reduced libido and erectile difficulty. These require psychological or medical intervention, not supplements.

Vascular health. Erectile function depends on blood flow. Smoking, high cholesterol, untreated hypertension, and diabetes all damage blood vessels and impair erectile capacity. Addressing these root causes is more impactful than any supplement.

Medications. SSRIs, beta-blockers, antihistamines, and several other common drugs can reduce libido or impair sexual function. If you suspect a medication is affecting your sexual health, discuss alternatives with your prescriber rather than adding a supplement.

Shilajit sits in this broader picture as one modest, evidence-early input. It may support hormonal and reproductive health at the margins, but it cannot overcome sleep deprivation, sedentary lifestyle, chronic stress, or untreated medical conditions.

What the evidence does not support

Several common shilajit-and-sex claims go beyond what any research shows. Being honest about these gaps is important for setting realistic expectations.

"Shilajit treats ED." No trial has tested shilajit for erectile dysfunction. ED is a medical condition with complex causes. Shilajit is a supplement, not a treatment. If you experience persistent ED, see a urologist.

"Shilajit increases penis size." No evidence exists. This is fiction.

"Shilajit works in hours." Every positive trial ran for at least 60 to 90 days of daily use. There is no acute effect. If you feel something on day one, that is placebo, not pharmacology. See how long shilajit takes to work.

"Shilajit replaces hormone therapy." A 20% testosterone increase within the normal range is not hormone replacement therapy. Men with clinically low testosterone (hypogonadism) need medical evaluation, not supplements. A 2024 systematic review of "testosterone booster" supplements by a team of urologists found that most marketed products lack verification of their claimed benefits, a reminder to approach any testosterone supplement, including shilajit, with realistic expectations (Morgado et al., 2024, International Journal of Impotence Research, PubMed).

Safety considerations for sexual health use

The safety profile of shilajit at 200 to 500 mg/day is well-tolerated in published trials, but purity is the determining factor.

A 2025 analysis found thallium in five of six commercial shilajit products (Kamgar et al., 2025, PubMed). Heavy metals can themselves damage reproductive health: lead and cadmium are documented endocrine disruptors that reduce sperm quality and testosterone. Taking a contaminated shilajit product for reproductive health is self-defeating. Only use products with batch-specific third-party heavy-metal testing. For tested options, see best shilajit supplements.

Shilajit is not recommended during pregnancy or breastfeeding. It may interact with blood pressure and thyroid medications. For the complete safety profile, see shilajit side effects. For dosing, see shilajit dosage.

Why we sell shilajit, honestly

Our Shilajit Adaptogen Complex is a general wellness capsule, not a sexual performance product. We sell it because the evidence for testosterone support and mineral replenishment is real, if modest. We do not market it for ED, size, or acute sexual effects because the evidence does not support those claims. Every batch is third-party tested for heavy metals, because selling a contaminated product for reproductive health would be contradictory. For the timing and dosage guidance that matches the clinical trial protocols, see best time to take shilajit.
