Treating unexplained infertility: Answers still needed

One of the most common treatments for unexplained infertility is ovulation induction, in which a woman takes drugs that will increase the number of eggs the ovary releases in the hope that at least one will result in a pregnancy. But when too many eggs are available for fertilization, the rates of high-risk multiple pregnancies go up. A recent study compared three drugs used for ovulation induction and found that the one more likely to result in a live birth was also more likely to result in a multiple pregnancy (twins, triplets, or more). The options for treating unexplained infertility remain less than ideal, but careful choices mean that the pregnancies that do result will be safer for moms and babies.
