Sperm production in human and other mammals is dependent on the temperature of the testicles,Sperm is optimally produced when the testicles are 2_4 C below body temperature .The increased testicular temperature may affect both quality and quantity of sperm produced.
Greater thanks for you... what about the physiology and histological measurements to keep the ideal temperature at this level....?
The function of the testis requires a special location of the testis outside the body in the scrotum, a sack of skin constitutes a thermoregulatory system that keeps the testis at a below body temperature , 35 ° C in men. The cremaster muscles also play a role in allowing the testes to move away or closer to the heat of the body, this condition is essential for the production and vitality of sperm
The process of spermatogenesis is highly sensitive to fluctuations in the environment, particularly hormones and temperature.
When body temperature increases as in febrile illness, the spermatogenesis is inversely affected.
increase temperature affect soermatogenesis that is why the testis out side the body and according to the temperature it become ditend ed or contract to keep nearrly fixed temperature
Heat exposure to the scrotum has a significant impact on spermatogenesis, decreasing and interrupting it. Spermatogenesis, which produces 1,000 sperm per second, is the most high-throughput process in the human body. As a result, the testicles are anatomically built to stay 4°C cooler than the rest of the body.
