Give scientific reasons for the following statements:
Testes are situated outside the abdominal cavity.

Explanation

Sperms are reduced by the testis.
`rarr` The temperature of testis remains `2-3^(@)C` lower than the body temperature which is optimal for the formation of sperms.
`rarr` If testis remain in abdominal cavity, then at the higher temperature, testes are unable to produce sperms.
Hence, testes are situated outside the abdominal cavity.
