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 |
Leydig cells:
1. | Are present in seminiferous tubules and secrete androgens |
2. | Are present in seminiferous tubules and help in the maturation of sperms |
3. | Are present in interstitial space and secrete androgens |
4. | Are present in interstitial space and help in the maturation of sperms |
