Optimal spermatogenesis requires testicular temperature to remain slightly below core body temperature. The scrotum, pampiniform plexus, and cremasteric reflex work collectively to regulate heat.
Prolonged heat exposure—such as frequent sauna use, tight clothing, or prolonged sitting—can impair sperm production. Occupational heat exposure is an underrecognized cause of subfertility.
Patient education on thermoregulation is a erotic simple yet effective preventive measure in fertility preservation.
