Those person in which testes does not descend into scrotal sac
show normal secondary sexual characters as the Leydig cells are unaffected
are normal in every respect except that they lack ability to procreate
the testes are comparatively smaller in size
all of these
but actually in my point of view if testis unable to decend into scrotal sac than it remains in the abdomen and it does not able to produce sperm .exception is only in case of elephnats
