Selenium is a trace mineral that plays an important role in male reproductive health, with a moderate level of scientific evidence supporting its use. Several studies have shown that selenium is essential for spermatogenesis and proper testicular function. Selenium is a crucial component of selenoproteins, such as glutathione peroxidase, which protect sperm cells from oxidative damage. Oxidative stress is known to impair sperm motility, morphology, and DNA integrity, all of which are vital for male fertility. Clinical trials and observational studies have reported that selenium supplementation can improve sperm motility and overall semen quality, particularly in men with low selenium status or infertility issues. For example, a randomized controlled trial published in the "Journal of Urology" (2003) demonstrated that selenium, sometimes in combination with vitamin E, improved sperm motility in infertile men. However, while these findings are promising, not all studies have shown consistent results, and the benefits may be limited to individuals with selenium deficiency. Current evidence suggests that selenium supplementation is not recommended for all men but may be beneficial in specific cases of male infertility linked to low selenium levels. Overall, selenium's support for the male reproductive system is scientifically validated, but the strength of evidence is moderate (3/5), and further research is needed to clarify optimal dosing and target populations.
