ABSTRACT

Contraception (birth control) prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation. There are different kinds of birth control that act at different points in the process.

The rapid increase in the world population makes it mandatory to develop new contraceptive methods. According to WHO data, every year 200 billion new pregnancies occur and more than 50 billion of them are classified as unintended.

To avoid complications of these unintended pregnancies and abortions, the contraception and kinds of contraceptive methods should be well known and understood. Recently, new hormonal contraceptive choices and regimen were adminestered and studies about male contraception and immunocontraception were performed. In this review, we discussed about the new development and progress on contraception.
