Just as women need the right balance of hormones to ovulate regularly, men need certain hormones to produce healthy sperm. Surprisingly, the same substances control these reproductive functions in both men and women — so the same fertility drugs that stimulate ovulation stimulate sperm production.
The catch is that the drugs don't perform nearly as well for men (success rates are about a third of those for women), and the FDA hasn't yet approved them for use in men, though a specialist can prescribe them. Very few studies have been done on the effects of fertility drugs on men, and those few agree on just one thing: The drugs can help only men with specific hormonal imbalances.
The drugs and how they work
The two most popular fertility drugs for women, clomiphene and human menopausal gonadotropin (hMG) used with human chorionic gonadotropin (hCG), are also used to treat men with primary hypogonadotropic hypogonadism — a hormone deficiency in the pituitary gland or hypothalamus that prevents the testicles from receiving the signal to make sperm.
Clomiphene (taken daily as a pill) prompts the pituitary gland to make luteinizing hormone and follicle-stimulating hormone, which tell the testicles to produce testosterone and possibly more sperm. HCG (injected two to three times a week, sometimes with hMG) prompts the testes to produce testosterone and sperm directly.
Is it for you?
Your doctor may prescribe fertility drugs if you have a hormonal imbalance (originating in the pituitary gland or hypothalamus) linked to a low sperm count; sometimes a doctor will also prescribe them for poor sperm quality and motility (its ability to move). (To learn about other factors that can cause fertility problems in men, see our article.)
Length of treatment
For men, a cycle of clomiphene consists of taking one pill a day for three to six months, and a cycle of hCG means having two to three injections a week for six months. (If your body doesn't respond to hCG, your doctor may suggest that you also take hMG.)
Taking fertility drugs for longer periods doesn't improve your chance of success, so if you take one for more than three months and your partner doesn't get pregnant, your doctor may increase the dosage, switch you to another medication, or, most likely, suggest another kind of treatment. However, as long as your hormone levels stay normal, you can safely take clomiphene in low doses for six months to a year
