Reproductive Endocrinology and Infertility (REI) was officially recognized as a subspecialty in the United States in 1972. The first US baby born as a result of in vitro fertilization dates back to 1981. Since then, the field of reproductive medicine has witnessed dramatic medical and technological advances. Our relatively new subspecialty accounts for more than 8 million births, a drop in the ocean of the 7,625 million worldwide, but our field has just started.
