Extra-abdominal cavity (Scrotum)

Vedclass · Answer

(C) In mammals,the testes are situated outside the abdominal cavity within a pouch called the scrotum. This extra-abdominal location is essential because the process of spermatogenesis requires a temperature approximately $2-2.5^{\circ}C$ lower than the normal internal body temperature. The scrotum helps in maintaining this lower temperature,which is necessary for the production and survival of sperm.
