Fertility drugs for women

What are common fertility drugs for women?
Your doctor may have you try one of these standard medications, which may be all you need to get pregnant:
  • Clomiphene works by stimulating the hormones in your brain that trigger an egg (or several) to develop and be released from your ovaries.
  • Gonadotropins stimulate your ovaries directly to produce an egg (or several).
Some women need to combine these drugs with intrauterine insemination (IUI) or an assisted reproductive technology (ART) procedure, such as in vitro fertilization (IVF). Women undergoing IVF also take other types of fertility medications to prepare the lining of the uterus for pregnancy and to prevent the ovaries from releasing eggs early.

How does fertility medication differ?

That depends on the woman and why she's having trouble getting pregnant. For instance, women with polycystic ovarian syndrome (PCOS) generally respond well to clomiphene, but those who don't may be given the insulin-sensitizing drug metformin to help them ovulate. Some women with PCOS respond well to a combination of metformin and clomiphene.
Women with hyperprolactinemia have too much of the hormone prolactin in their blood, which interferes with ovulation. Women with this condition who want to conceive will most likely take bromocriptine or cabergoline to restore ovulation.

What are the risks of fertility drugs?

Many of these drugs have been used safely and successfully for more than 40 years. But like other fertility treatments, these drugs can increase the chance of conceiving multiples – and the more babies a woman carries, the greater the risk of complications, including miscarriage and premature labor. About 10 percent of women who take clomiphene have multiples (mostly twins), and about 30 percent of women who take gonadotropins have multiples (again, mostly twins).

Does a past abortion affect my chances of getting pregnant?

Probably not. However, in rare cases, multiple dilations and curettages (the cleaning out of the uterus, also known as a D&C) can cause scarring at the top of the cervix or inside the uterus. A procedure called hysteroscopy (when a small camera is placed through your cervix into your uterine cavity) can check for this problem and usually repair the scar tissue at the same time. But even if that's not the case for you, you should know that any procedure that dilates the cervix – a necessary step during most abortions – can weaken it. So if you've had more than one abortion and you get pregnant again later on, you may find that you have what's known as an incompetent cervix, a cervix that starts dilating prematurely. This can sometimes be treated with a stitch to keep the cervix closed, called a cerclage. On the bright side, having conceived before proves that you ovulate and that your fallopian tubes are open.

Common causes of fertility problems in men

About 11 percent of reproductive-age couples in the United States have trouble conceiving or sustaining a pregnancy. About one-third of these cases are due to male fertility problems, about one-third are related to female fertility problems, and the rest are due to factors involving both partners or to unexplained causes. If you've had regular, unprotected sex for more than a year (or six months if you're older than 35) without conceiving, see your doctor. About 65 percent of couples that get treatment for a fertility problem are eventually able to have a successful pregnancy, according to Resolve, the national infertility association. A fertility specialist will usually give you and your partner an initial examination. If a semen analysis isn't normal, or if anything in your medical or reproductive history indicates you need a more thorough evaluation, you may be referred to a urologist or other male reproduction specialist who can recommend treatment and help you...
