The Suleman octuplets are six males and two females, conceived via in vitro fertilization (IVF) and subsequently born to Nadya Suleman on January 26, 2009, in Bellflower, California. Residing in Lancaster, California, they are the first known octuplets to survive their infancy. The extremely controversial circumstances of their high-order multiple birth have led to debates in the field of assisted reproductive technology and an investigation by the Medical Board of California of the fertility specialist involved in the case.
