Nearly 2 million women report using these drugs, three times more than the numbers requiring other infertility treatments.
Fertility drugs can correct infertility by altering a woman s hormone levels.
Hormones are responsible for the egg s release from the ovaries and attachment within the uterus. Through a delicately timed interplay, hormones set the stage for the pregnancy. If hormone deficiencies are determined to be a factor in the infertility, drugs can serve as hormone supplements or hormone boosters. They can trigger ovulation to occur and hyperstimulate the ovaries to produce more than one egg to improve the chances of conception. However, clomiphene citrate increases the likelihood of multiple births because more than one egg may be released.
