PROVIDENCE – It is estimated that approximately 10 percent of women of child-bearing age may be unable to get pregnant or to carry a pregnancy to term. While recent years have seen a tremendous growth in fertility treatments and options, many assisted reproductive technologies like in vitro fertil- ization (IVF) and embryo transfer are very expensive and not often covered by insurance. Many women, especially those with unexplained infertil- ity, are commonly treated with ovarian stimulation medica- tions – letrozole, gonadotropins or clomiphene citrate. Not only is this course of treatment quite successful, it is also significantly less costly. The challenge has been to deter- mine which medication is best at achieving and maintaining pregnancy while reducing multiple gestations.
