There is no evidence to suggest that abortions without complications cause an adverse effect on female fertility. Complications such as infection or a form of scarring post-surgical procedure can lead to problems which can impair fertility, however these occurrences are rare and can also be treated. Commonly, fertility returns quite quickly post abortion, and for this reason contraceptive measures are often discussed soon after the time of the abortion.
