Does scrotal moisture affect sperm survival rate?

Moisture in the scrotum may have a certain impact on sperm survival rate. Moisture in the scrotum is usually related to factors such as increased local temperature and accumulation of sweat, which may interfere with the normal living environment of sperm.

The scrotum needs to be maintained at a temperature slightly below body temperature to ensure normal sperm development. A humid environment may cause local heat dissipation to be blocked, causing the scrotal temperature to rise. Continuous high temperature will inhibit testicular spermatogenesis and reduce sperm motility and survival time. The salt and metabolites in sweat can irritate the skin for a long time and may cause dermatitis or eczema, which indirectly affects testicular health. This kind of situation can be improved by keeping the area clean and dry, choosing breathable underwear and other measures.

In rare cases, scrotal moisture may be accompanied by varicocele, chronic prostatitis and other diseases. These diseases themselves can affect sperm quality, and moisture is just an accompanying symptom. Varicocele can cause testicular blood pooling and abnormal temperature regulation, and prostatitis may damage sperm through inflammatory factors. At this time, it is necessary to treat the original disease. Simply improving the damp symptoms cannot solve the underlying problem.

It is recommended that when long-term scrotal moisture and infertility problems occur, you should promptly see an andrology or reproductive medicine department to check the semen quality. You should avoid sitting for long periods of time, wearing tight pants, etc., dry your perineum thoroughly after bathing, and give priority to pure cotton breathable underwear. If it is accompanied by itching or rash, antifungal ointments such as bifonazole cream must be used under the guidance of a doctor, and avoid using hormone-containing products on your own.
