Post-coital oral emergency contraception is used for the prevention of pregnancy after intercourse. The contraception comes in the form of pills, often collectively referred to as morning-after pills. Post-coital use of morning-after pills separates them from traditional contraception which is either a continual preventative process, such as the birth control pill, or used during intercourse, such as condoms. Oral emergency contraception is important to embryology because it represents a significant accomplishment in the human ability to manipulate the process of embryonic development and pregnancy. Though there are still many misunderstandings about the morning-after pills as a contraceptive method, the continued efforts of scientists to carry out research on emergency contraception suggests that the technology may continue to improve and grow into more widespread use.
