Contraceptives:
Contraceptives are devices, methods or drugs that help in preventing pregnancy.

Coitus interruptus :
Coitus interruptus is a natural or traditional method of contraception. In this method, just before ejaculation, the male partner withdraws penis from the vagina. This is done to prevent the release of sperms in vagina (insemination).

Condoms and vaults :
Condoms and vaults are a barrier method of contraception made up of rubber. They prevent the physical meeting of sperm and ovum.

Multiload 375 :
Multiload 375 is a copper releasing intrauterine device. It releases copper ions in the uterus to suppress the motility of sperms, so that they cannot swim and reach the fallopian tube for fertilisation.

Vasectomy :
Vasectomy is a surgical contraceptive method performed in males. In this method, a small part of the vas deferens is removed or tied up through a small incision on the scrotum, to prevent the movement of sperms from the vas deferens to the urethra.
