Answer:
D. It keeps the temperature lower for sperm development
Explanation:
<u>Semineferous epithelium ,of the seminiferous tubules, of the testis is the site of sperm production (Spermatogenesis) , and highly sensitive to elevated and fluctuating body temperature of man. Elevated temperature affect the survival of spermatids , the spermatozaon, and therefore affects spermatogenesis</u>.
To avoid this the testis is located outside the body in the scrotal sack.This positioning aids shielding away of the elevated body temperature; thereby survival of spermatozoan.
The attachment in the scrotal sack is done by the cremasteric muscles of the scrotum. This muscle positions the testis in the best angle to reduce temperature conduct from the body.
It also help by contracting and relaxing, to adjusts the temperature of the testis depending on the environmental temperature.During cold showers,it constricts pulling it close to the abdomen, and after, relaxes returning it to normal position.
