| 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 |
