Do birth control pills cause infertility?

birth-control-pills-NJThis is one of the most common questions patients ask their fertility doctors and/ or their OBGYNs. Fortunately the short answer is no and this is backed up by large research studies. While their purpose may be to prevent pregnancy, the contraceptive effect of the pill wears off rather quickly. In some women the return to normal cycles and fertility can take a number of months, but usually there is not much of a delay. In other women, such as those with ovulation disorders such as PCOS, coming off the pill may actually increase the chances for conception. If your cycles have not regulated themselves 6 months after stopping the pill or they are becoming less regular over time after then and you’re trying to get pregnant, it’s probably not the pill, and it’s time to discuss this with your GYN or fertility specialist.

Is taking fertility drugs doping?

Apparently according to the NFL, it is. One of the players on the Indianapolis Colts was suspended after taking clomiphene, a fertility pill commonly used by Fertility SpecialistsOBGYNs and Urologists to help women (and sometime men) coping with infertility. Even though he was using it to help his wife get pregnant, successfully I might add, the NFL considers Clomid a “performance enhancing drug.” Most patients who have taken clomiphene, and put up with some its side effects would likely take issue with that assessment.

Fertility drugs and breast cancer

fsh penOne of the most common questions patients ask us when they are about to start fertility drugs, is are they are safe? This question comes up whether they are going to start pills (Clomid, Femara) or injectable fertility drugs (Follistim, Gonal-F, Bravelle, Menopur). Unfortunately, the answers are not always so clear cut as we would like. One of the major concerns women have is about cancer, and the cancer which more women seem to fear than any other is breast cancer. In the past there have been questions about whether fertility drugs increase the risk of breast cancer. A recent study may help to reassure anxious couples. The researchers followed fertility patients from multiple institutions and showed that women treated with fertility drugs, both oral and injectables had the same rates of breast cancer as those who were not. The only exception was women with who took clomid for over year, who did have a slightly higher rate of breast cancer, another good reason to be proactive and see a fertility specialist early on.

Overweight fertility patients may need higher medication doses

cetrotide-princetonMost Reproductive Medicine specialists know that our overweight patients often need higher doses of fertility medications, whether that is pills (clomiphene or Femara), or injections (Follistim, Gonal-F, Bravelle or Menopur). When we do IVF cycles, we also add a medication to prevent ovulation such as Lupron, Ganirelix or Cetrotide, and for the most part, the doses are not adjusted based on a patients weight. It turns out that doctors in Colorado looked at one of these drugs, Cetrotide (Cetrorelix) and found that overweight women actually metabolize the drug faster, meaning that the currently used dosing may not be sufficient in these patients. So, what does that mean? If the cetrotide does not last in the system long enough, premature ovulation may occur, and your IVF cycle could be cancelled. It may mean that we need to use higher or more frequent dosing in heavier women.
