       Reproductive Health

Birth control is a term for several techniques and methods used to prevent fertilization or to interrupt pregnancy at various stages. Birth control techniques and methods include contraception , contragestion and abortion.

Contraception includes barrier methods, such as condoms or diaphragm, hormonal contraception, also known as oral contraception, and injectable contraceptives. Contragestives, also known as post-coital birth control, include intrauterine devices and what is known as the morning after pill.

The most common methods of hormonal contraception include the combined oral contraceptive pill and the minipill. Hormonal emergency contraception can be both contraceptive and contragestive.

           Sterilization

Surgical sterilization is available in the form of tubal ligation for women and vasectomy for men. Although sterilization is considered a permanent procedure due to the uncertainty of reversal possibility, it is possible to attempt a tubal reversal to reconnect the Fallopian tubes in females or a vasectomy reversal to reconnect the vasa deferentia in males. The rate of success depends on the type of sterilization that was originally performed and damage done to the tubes as well as the patient's age.

          Vasectomy

A vasectomy is a minor surgical procedure for male sterilization and birth control. During the procedure, the vasa deferentia of a man are severed/and then tied in a manner which prevents sperm from entering into the seminal stream. Vasectomy should not be confused with the surgical removal of the testicles.
