The testes are situated outside the abdominal cavity within a pouch called the scrotum. This is necessary as:

1.  The scrotum can contain lengthy ducts for the transfer of sperms
2.  Scrotum helps in maintaining the low temperature of the testes necessary for spermatogenesis
3.  Scrotum reduces the pressure around the testes necessary for spermatogenesis
4.  Scrotum can store huge amounts of sperms
