1 Answer

Comment
A)
Condoms: They are barriers made of thin rubber/latex sheath that are used to cover the ***** in the male or ****** and cervix in the female, just before the coitus so that ejaculated semen never enters into female reproductive tract. Both male and female condoms can be self-inserted, disposable thus giving privacy to the user.

Diaphragms, Cervical caps and Vaults: They are all barriers, made up of rubber and are inserted into the female reproductive tract to over the cervix during coitus. They prevent conception by blocking the entry of the sperms through cervix and are reusable. Spermicidal creams, foams and gels are used along with these barriers to increase their contraceptive efficiency.
