Oral contraception (the pill). Oral contraceptive pill (OCP) is a contraceptive
drug taken orally in order to prevent pregnancy. Hormonal contraception represents substances that act like estrogen and progestin. These substances will prevent the release of gonadotropins from the hypothalamus and pituitary, resulting in failure to reach the maximum concentration of LH and FSH and ovulation does not occur, as described in Birth Control Pills (Oral Contraceptives).
There are two formulations of oral contraceptive use in women:
– The contraceptive pill, containing estrogen and a progestin, taken once daily.
– The mini pill, which contains only a progestin, also taken once a day.

The success of the patch and other contraceptives depends on patient compliance to treatment and the effectiveness of the method. Well-used contraceptive methods are very effective. But doctors say that more oversight or indifference to treatment is less effective. For example, 47-50% of women using birth control pills miss one pill per cycle, while 22% reported 2 or more pills forgotten.
