The testes are located outside the body in the scrotum to maintain an optimal temperature for sperm production. Sperm development requires a temperature slightly lower than the body’s core temperature.
Exposure to excessive heat can disrupt spermatogenesis and reduce sperm quality. Sources of heat exposure may include hot baths, saunas, tight clothing, and prolonged sitting.
One condition associated with impaired temperature regulation in the scrotum is Varicocele, which involves enlargement of the veins within the scrotum.
This condition can increase scrotal temperature and reduce erotic sperm production. Surgical treatment may improve fertility outcomes in affected individuals.
