In barrier methods of contraception, ovum and sperms are prevented from physically meeting with the help of barriers i.e., they prevent fertilization. Such methods are available for both males and females.

(i) Condoms : These are barriers made of thin rubber or latex sheath that are used to cover the penis in the male or vagina and cervix in the female, just before coitus so that the ejaculated semen would not enter into the female reproductive tract. This can prevent conception. 'Nirodh' is a popular brand of condom for the male. Use of condoms has increased in recent years due to its additional benefit of protecting the user from contracting STDs and AIDS. Both the male and the female condoms are disposable, can be self-inserted and thereby gives privacy to the user.
