| No. Extended use of oral contraception to avoid menstruation does not cause infertility or delay the return of fertility. In fact, other than sterilization, which is intended to permanently end fertility, no method approved by the U.S. Food and Drug Administration leads to infertility. Fertility returns immediately after women stop using IUDs, barrier methods such as the diaphragm, or hormone methods, including the pill, the patch, or the ring. However, some women who use the shot — DMPA or Depo-Provera — may not be able to become pregnant for up to 18 months.
It may be helpful to know that the monthly bleeding that happens for women who use hormonal contraception is not the same as menstruation. Menstruation only occurs to prepare the body for the next possible pregnancy. The contraceptive hormones that prevent ovulation also prevent the body’s preparation for pregnancy. The bleeding that occurs during the use of hormonal contraception results from the withdrawal of estrogen and progestin, instead of the surge of estrogen associated with the physiological onset of menstruation. |
