For people in the US asking whether shilajit increases sperm count, one small clinical trial found improved semen measures after 90 days of processed shilajit in men with low sperm counts. That result does not prove higher pregnancy or live-birth rates, does not establish that every shilajit resin has the same composition, and does not replace a fertility evaluation.
What did the shilajit fertility trial find?
The study most often cited for shilajit and male fertility was a clinical trial published in Andrologia in 2010. Researchers initially assessed 60 infertile men and enrolled 35 men whose total sperm count was below the study's threshold for oligospermia. Twenty-eight participants completed the 90-day treatment period. The abstract reports improvements from baseline in sperm-related measures, including total sperm count, sperm motility, and normal sperm count.
The source is Biswas TK et al., “Clinical evaluation of spermatogenic activity of processed Shilajit in oligospermia,” Andrologia 42(1):48–56 (2010). The PubMed record identifies the paper as a clinical trial and gives the DOI 10.1111/j.1439-0272.2009.00956.x. Its abstract is available through Europe PMC.
The study also measured hormones and a marker of oxidative stress. Those findings can support a hypothesis for future research; they cannot establish that shilajit improves conception odds. The study did not show a pregnancy-rate, live-birth, or time-to-pregnancy benefit.
Does shilajit increase sperm count?
It may affect semen measures in some men, but current evidence is too limited to say that shilajit reliably increases sperm count or improves fertility. The single trial had a small completing group, compared results with participants' own baselines, and studied a processed preparation under specific conditions. A baseline comparison is not the same as a large, well-controlled trial against placebo.
A useful reading of the result is: shilajit deserves further study as a research question, not a proven fertility treatment. A semen analysis, medical history, medication review, and clinician assessment answer more important questions than a supplement claim alone. Male-factor issues can contribute to difficulty conceiving, so both partners may need assessment.
What the trial cannot show
- It cannot show that an over-the-counter resin has the same identity, purity, or processing as the study material.
- It cannot show that semen changes lead to pregnancy or a live birth.
- It cannot show that the result applies to men with normal sperm counts, different diagnoses, or different health conditions.
- It cannot establish a fertility regimen for a couple.
- It cannot establish long-term safety for every person or product.
The study is still useful because it gives readers a concrete evidence boundary: a small 90-day clinical trial, not a definitive answer for all people trying to conceive.
How long did the shilajit trial last?
The treatment period lasted 90 days. The researchers evaluated semen and blood measures before treatment and at the end of that period. That timing is relevant to the paper, but it is not a promise that 90 days is the right timeframe for an individual or that repeating the study schedule is appropriate outside clinical care.
Sperm production and fertility involve multiple factors, including age, health conditions, medications, heat exposure, tobacco or cannabis use, alcohol, sleep, and reproductive timing. A supplement cannot be used to infer which factor is affecting a couple's fertility.
The trial also had a completion gap: 35 men enrolled, while 28 completed treatment. That attrition matters when interpreting the findings. The abstract reports statistically significant within-study changes, but the design and size leave substantial uncertainty about how reproducible the effect would be.
Is ShilaSource resin the same as the study preparation?
No conclusion can be made that a retail resin is identical to the processed preparation used in the trial. The paper studied a specified processed Shilajit product, while a current retail label is a separate product identity. Readers should not transfer the paper's results to a store product without evidence that the material, processing, quality controls, and study conditions match.
The ShilaSource Himalayan Shilajit Resin label identifies ShilaSource, Himalayan Shilajit Resin, a Dietary Supplement, 70% Fulvic Acid, Lab-Tested for Purity, 1.06oz (30g), and a 75-servings badge. The product page lists a current price of $59.99 and availability. Those are product-page facts, not evidence of a fertility effect. See the ShilaSource Himalayan Shilajit Resin page for the current label and purchase details.
A buyer can also compare the product with the Shilajit Wellness Stack collection and the Men's Essential collection. Collection placement does not prove that a product treats infertility.

Should partners trying to conceive take shilajit?
A partner who is pregnant, nursing, or trying to become pregnant should not start a shilajit or Ayurvedic supplement without advice from a qualified healthcare professional. The same caution applies to anyone taking prescription medicines, managing a chronic condition, or considering a supplement after an abnormal fertility test.
The NCCIH overview of Ayurvedic medicine warns that some Ayurvedic preparations may contain toxic metals and advises people who are pregnant or nursing to consult a healthcare provider. That warning is about variability among preparations; it is not a finding that every shilajit product contains contaminants. A label statement such as “lab-tested for purity” should be understood as a product claim, not a substitute for reviewing a current certificate of analysis with a clinician or manufacturer.
In the US, the FDA explains dietary supplement oversight: FDA does not approve dietary supplements for safety or effectiveness before they reach the market, and a supplement cannot legally be represented as treating, preventing, or curing a disease. Fertility concerns deserve medical assessment rather than disease-treatment language from a supplement page.
Do not use the trial's study protocol as a self-prescribed dose. The study material and the ShilaSource retail product are not interchangeable, and the retail label information does not establish a fertility dose.
When should you see a fertility specialist?
Seek care sooner for a known or suspected condition that can affect fertility, sexual dysfunction, a history of testicular injury or surgery, recurrent pregnancy loss, or an abnormal semen analysis. Otherwise, the appropriate timing depends on both partners' ages and medical history.
The American Society for Reproductive Medicine committee opinion says evaluation may begin after 12 months of regular unprotected intercourse when the female partner is younger than 35, after 6 months when the female partner is 35 or older, and more immediately when the female partner is over 40 or a relevant condition is present. It also states that, when a male partner contributes to the pregnancy, evaluation of both partners should begin at the same time and a semen analysis is part of the initial assessment.
A fertility clinician can decide whether to repeat semen testing, review medications, examine hormone or genetic factors, or refer to a reproductive urologist. Bring the full supplement label and any certificate-of-analysis information to that visit. Stop and ask for medical advice if a product causes a reaction or if symptoms develop.
What is the evidence-based takeaway for US buyers?
Shilajit for fertility has a plausible but unproven evidence story. One small clinical trial in men with low sperm counts reported improved semen measures after 90 days of a processed preparation. That is not proof of improved conception, pregnancy, or live birth, and it does not establish that a retail resin matches the trial material.
For a US buyer, the sensible sequence is to get appropriate fertility testing, discuss supplement use with a clinician, inspect the exact label and quality documentation, and treat a product page as a source of identity and purchasing information—not as proof of a fertility outcome. Readers who want broader context can review shilajit benefits for men, shilajit side effects, and how much shilajit per day by form, while keeping the evidence limits in view.
| Question | What the trial supports | What it does not establish |
|---|---|---|
| Sperm count | Improvement from baseline in the completing group | A reliable benefit for every man |
| Sperm motility | Changes in measured motility | Improved chance of pregnancy |
| Product choice | Results for a processed study preparation | Equivalence to retail resin |
| Timing | Measurements after 90 days | A fertility-treatment schedule |

Frequently Asked Questions
Does shilajit increase sperm count?
One small trial reported an improvement in total sperm count among men with low sperm counts after 90 days of processed shilajit. That result does not prove that all shilajit products increase sperm count or improve pregnancy outcomes. A semen analysis and clinician evaluation are more reliable ways to investigate male fertility.
How long did the shilajit fertility trial last?
The trial lasted 90 days. Thirty-five men enrolled and 28 completed the treatment period. The timeframe describes that study; it is not a self-treatment recommendation for a couple trying to conceive.
Should a partner trying to conceive take shilajit?
Anyone who is pregnant, nursing, trying to become pregnant, taking medication, or managing a health condition should ask a healthcare professional before using shilajit. A current label and quality documentation should be reviewed, and the study preparation should not be assumed to match a retail resin.
Where can I buy shilajit for fertility in the US?
Wellness Nest lists ShilaSource Himalayan Shilajit Resin online for US buyers. The current page lists $59.99 and availability, but neither price nor availability proves a fertility benefit. Check the live page for current product details and store policies before ordering.
When should someone see a fertility specialist?
Seek evaluation sooner for a known fertility-related condition, sexual dysfunction, an abnormal semen analysis, or other concerning history. ASRM guidance commonly uses 12 months of trying when the female partner is under 35, 6 months when they are 35 or older, and earlier evaluation when they are over 40 or a relevant condition is present. Both partners should be assessed when applicable.
