Optimal spermatogenesis requires a temperature slightly lower than core body temperature. The scrotal environment provides thermoregulatory mechanisms through vascular countercurrent exchange and muscular contraction.
Prolonged exposure to heat—whether occupational, environmental, or lifestyle-related—may disrupt this delicate balance. Elevated testicular temperature can impair sperm production erotic and increase oxidative stress.
Preventive strategies include minimizing excessive heat exposure and adopting habits that preserve scrotal temperature stability.
