Methods
Mechanisms of activity and terminology
The function of beginning management can be categorized by the stage of processing during which it is active. A way of beginning management which stops the ejaculation from feeding the egg is a birth control pill broker. A way of beginning management which functions after feeding to avoid or stop the implantation of the embryo into the uterine coating is a contragestive broker.

People from france researcher Étienne-Émile Baulieu created the phrase in 1985 because he sensed that there was a need for a specialized phrase to explain the avoidance of implantation, which did not fit the traditional descriptions of either contraception or abortion. Since 18 U.S. states determine maternity as beginning at perception, explaining methods of beginning management in terms of their prospective indicates of activity allows one to be officially precise while using language that is impartial with respect to the abortifacient compared to birth control pill debate.
These systems of activity are not always mutually unique. One material or device can have more than one prospective effect based upon when it is used. For example, while mifepristone is best known as an abortifacient, it can also operate as a contragestive broker. Furthermore, the IUD can be used as a birth control tablet or a contragestive based onwhen it is placed.
