Fertility drug.

Fertility drug, any of a variety of substances used to increase the possibility of conception and successful pregnancy. Different methods are used to correct or circumvent the many different functional disorders of both males and females that can interfere with conception and childbearing (see infertility). The term fertility drug primarily refers to drugs that mimic or stimulate production of a hormone necessary for conception, but it may also be used to refer to the hormones themselves, when they are administered as part of a program of infertility treatment.
