Expert Answer:

There are various methods of contraception used. These include the following:

1) Mechanical methods of birth control are:

i) Male Condom 

ii) Female Condom

Both of these prevent the sperm from meeting the egg.

iii) Intrauterine Device (IUD) – a T-shaped device placed inside the uterus (by a doctor) which blocks the sperms from entry into the fallopian tubes

iv) Intrauterine System (IUS) – a device similarly designed and administered as the IUD which releases hormones that thicken the cervical mucus thus blocking sperms from entry into the uterus

v) Diaphragm, Cervical Cap, and Shield – latex or silicon cap used with spermicides which blocks the entry of sperms into the cervix

vi) Sponge – a soft, disk-shaped device that a woman wets and inserts into the vagina, and thus covering the cervix and blocking the sperms

2) Surgical methods: These are also called sterilisation. Surgical intervention blocks gamete transport and thereby prevents conception. Sterilisation procedure in male is called 'vasectomy' and in females it is 'tubectomy'.

3) Hormonal methods - Oral administration of small doses of either progestogens or progestogen-estrogen combinations is a method used by females in the form of pills. They can also be used by females as injections or implants under the skin.
