The first thing that usually comes to mind when people hear the term, "infertility treatment," is the risk of multiple births. This worry has been fueled by the recent highly publicized multiple births in Iowa and Texas.

Ectopic pregnancy, or preembryo implantation outside the endometrial cavity (i.e., fallopian tube, cervix, abdominal or pelvic cavity), is a potentially fatal condition with an incidence of 1:150 diagnosed pregnancies.

Lowering insulin levels with metformin in women with polycystic ovary syndrome but without overt diabetes increases the likelihood of conception and reduces risk of miscarriage, researchers report here.

Millions of couples who otherwise would not have been able to conceive children have benefited from advances in fertility treatment. But technological advances, improved access to fertility care as well as a growing demand from infertile couples have resulted in a global growth in the number of multiple births.
