Prevents entrance of sperms into vagina or uterus.
(a) The Condom:
The male wears a condom that covers the erect penis, and prevents deposition of sperms in the vagina. Condoms are made up of rubber from latex. Ejaculated semen is retained in the condom preventing their entrance into uterus. Condoms can be joint with spermicides inserted into the vagina. Condom also protects against sexually transmitted diseases (i.e., STD) such as syphilis and AIDS.
