Fertilisation of the human ovum by a sperm can be prevented by the following methods:
(a) Condoms made of thin rubber or latex sheath act as barriers. These are used to cover the penis in the male or vagina and cervix in females.
(b) Diaphragm, cervical caps and vaults are barriers made of rubber which are introduced in the female reproductive tract to cover the cervix.
