Diaphragms, cervical caps and vaults are barriers made of rubber that are inserted into the female reproductive tract to cover the cervix during coitus. They prevent conception by blocking the entry of sperms through the cervix. They are reusable.
Condoms are not reusable and are self-inserted by the user and disposable.
IUDs are ideal contraceptives for females who want to delay pregnancy and/or space children. These are inserted in the uterus through vagina and once inserted they are effective for years.
