A crucial part of conventional in vitro fertilization (IVF) — the incubation of embryos in a laboratory dish — can instead take place in a device inside the vagina, new research suggests.
Black Women Fare Worse with Fertility Treatments
Black women undergoing in vitro fertilization (IVF) are only about half as likely as white women to become pregnant using the popular assisted reproduction technique, new research indicates, and the racial disparity persists even when donor eggs are used.
