Q: If you've gotten pregnant through an infertility treatment such as intrauterine insemination (IUI) or in vitro fertilization (IVF), you may wonder if you have more to watch out for than women who've conceived the old-fashioned way.Are pregnancies that result from infertility treatment automatically considered high risk?
A: The treatments themselves don't make a pregnancy high risk; the medical issues that often cause female infertility, such as diabetes, endometriosis, fibroids or simply being older, may. ("Male factor" issues are responsible for the infertility approximately 40 percent of the time, but treatment is often the same.) However, up to 40 percent of such pregnancies result in twins. These pregnancies carry a three to six times higher risk for problems, such as high blood pressure, preterm delivery and low birth weight babies. Q: Is the miscarriage risk higher after treatment?
A: If a pregnancy makes it past the first trimester, the chance of miscarrying before 24 weeks is about 1 percent higher for single babies; for twins, it's 6 percent higher; and for triplets, it's 10 percent higher. Q: Is prenatal care any different?
A: In the first nine to 10 weeks, women receive supplemental estrogen and progesterone until the placenta is developed enough to support the pregnancy. After that, the standard of care is the same unless there are multiple babies.
