In the United States, infertility affects 1.5 million couples.[86][87] Many couples seek assisted reproductive technology (ART) for infertility.[88] In the United States in 2010, 147,260 in vitro fertilization (IVF) procedures were carried out, with 47,090 live births resulting.[89] In 2013 these numbers had increased to 160,521 and 53,252.[90] However, about a half of IVF pregnancies result in multiple-birth deliveries, which in turn are associated with an increase in both morbidity and mortality of the mother and the infant. Causes for this include increased maternal blood pressure, premature birth and low birth weight. In addition, more women are waiting longer to conceive and seeking ART.[90]

Consult your health care professional. Women of childbearing age may want to consider taking folic acid supplements to reduce the risk of having a pregnancy affected with neural tube defects. Many women and teenage girls don't get enough calcium or vitamin D, both of which are critical to healthy bones and avoiding osteoporosis. Some people with diabetes appear to benefit from chromium. Vegetarians, especially vegans, may want to consider supplements to obtain nutrients they aren't getting from animal products.
