Beta-sitosterol is a plant sterol commonly found in fruits, vegetables, nuts, and seeds. Its use to support the reproductive system, particularly male reproductive health, has some scientific basis, though evidence is moderate. Several studies have investigated beta-sitosterol for its potential benefits in managing benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland that can affect urinary and sexual function in men. Clinical trials have shown that beta-sitosterol can modestly improve urinary symptoms and flow measures in men with BPH, which indirectly supports prostate health, an important aspect of the male reproductive system. The mechanism is believed to involve inhibition of 5-alpha-reductase, an enzyme that converts testosterone to dihydrotestosterone (DHT), a hormone linked to prostate growth.

However, direct evidence for beta-sitosterol enhancing overall reproductive function (such as fertility or hormone regulation) in either men or women is limited. Its primary scientific support pertains to prostate health, rather than broader reproductive system function. There is little evidence supporting its use for female reproductive health. Thus, while beta-sitosterol is scientifically validated for certain aspects of male reproductive health, especially related to prostate symptoms, its effects on the wider reproductive system are less well established.
