why are sperms kept in scrotum sacs

Asked by bkstl123 | 22nd Mar, 2012, 03:43: PM

Expert Answer:

Sperm production occurs in testes, which are placed in scrotum sacs outside the body and not in abdominal cavity. 
Sperm production and survival need a temperature lower than the body temperature. Hence testes are placed outside the body which allows for air circulation to cool them to just the right temperature.
