What are the different methods of contraception?

Explanation

The various methods of contraception (preventing preganancy in woman) are: Barrier methods, Chemical methods, use of Loop of Copper-T, and Surgical methods.
i) In the barrier methods of preventing pregancy, the physical devices such as condoms and diaphragam (or cap) are used. Condoms are used by males (by putting them as a covering on the penis). Diaphram (or cap) is used by females (by putting it in the vagina to cover the cervix). Condom as well as diaphram prevent the sperms from meeting the ovum (or egg) by acting as a barrier between them.
ii) In the chemical methods of preventing pregnancy, the females use oral pills. The oral pills contain hormones which stop the ovaries from releasing ovum (or eggs) into the oviduct.
iii) The loop or copper-T are also very effective in preventing pregnancy. A loop or copper-T is placed inside the uterus by a doctor or a trained nurse. The loop or copper -T are called intra-uterine contraceptive device (IUCD).
iv) Surgical methods of birth control are available for males as well as females. In males, a small portion of the sperm duct (or vas deferens) is removed by surgical operation and both the cut ens are ligand (or tied) properly. This prevents the sperms from coming out. The surgical procedure carried out in males is called 'vasectomy'. In females, a smal portion of the oviducts is removed by surgical operations and the cut ends are ligated (or tied). This prevents the ovum (or egg) from entering into the oviducts. The surgical procedure carried out in females is called tubectomy.
