Why the testes in human beings and mammals are situated outside the abdominal cavity within a pouch called scrotum?
A
There is not enough space in the pelvic area for the testicles to be housed internally
B
The scrotum helps in maintaining the low temperature of testes, $2.5°C$ lower than normal body temperature required for spermatogenesis
C
The scrotum helps in maintaining the high temperature of testis, $2.5°C$ higher than the normal body temperature required for spermatogenesis
D
Providing more space for the growth of epididymis
Solution
Testes are extra-abdominal because for spermatogenesis, temperature required is $2.5°C$ lower than normal body temperature.
