Short answer
A low sperm count is improved, when it can be, by dealing with the cause and by not doing things that suppress production. Confirm which number is low. Stop unprescribed anabolic steroids only with medical advice, and do not start testosterone to treat the count. Lifestyle steps supported by NICE are about semen quality and general health, not a guaranteed rise of millions per millilitre.
Key takeaways
- Fix collection error and abstinence before you call the count a condition.
- Testosterone therapy and anabolic steroids are among the clearest suppressors.
- A three-month gap matches a cycle of sperm production. It is not a promise of recovery.
- Zinc plus folic acid did not improve semen quality or live birth in a large trial.
Confirm the figure
Concentration under 16 million/ml and total sperm number under 39 million are different findings. So is a sample that missed the pot. The preparation and count pages are the right check before any “improvement” plan.
Remove suppressors, carefully
The AUA/ASRM guideline’s clinical principle is that clinicians should not prescribe exogenous testosterone to a man interested in current or future fertility, because it can cause oligospermia or azoospermia. Recovery after stopping is usual but can take months or, rarely, years, and is not guaranteed. Anabolic steroids do the same kind of harm. If a doctor prescribed testosterone, the conversation about pausing it belongs with that doctor. This site will not give a tapering schedule.
What trials do not show
A large US randomised trial of folic acid and zinc in men seeking infertility treatment found no improvement in semen quality or live birth. That result is a useful brake on zinc marketing. Antioxidant combinations, in the 2022 Cochrane review, have very uncertain effects on live birth. Some smaller trials report higher concentration or count with CoQ10 or carnitine. Those reports are described with their limits and are not a prescription.
Medical treatment of the count
NICE discusses hormonal treatments in specific endocrine situations and is cautious where the evidence is weak. Varicocele repair is considered only for a varicocele felt on examination, with reduced semen parameters, when trying to conceive spontaneously. Surgery, sperm retrieval and ICSI are specialist decisions. None of them should be chosen from a content site.
Evidence
Limited evidenceAvoiding exogenous testosterone is a strong clinical principle for protecting sperm production. Evidence that lifestyle changes or supplements raise sperm count enough to change live birth is limited or insufficient, depending on the intervention.
Semen parameters
Some trials report changes in concentration or total count. Effects are inconsistent across ingredients, and a large zinc trial was negative.
Pregnancy and live birth
There is not reliable evidence that a general sperm-count supplement plan improves live birth. Antioxidant live-birth evidence is very low certainty.
A change in a semen measurement is not the same finding as a pregnancy or a live birth.
