The Suleman octuplets are six male and two female children conceived via in vitro fertilization (IVF) and subsequently born to Nadya Suleman on January 26, 2009, in Bellflower, California. They presently reside in La Habra, California. They are only the second full set of octuplets to be born alive in the United States and, having survived more than a week, surpassed the previous worldwide survival-rate for a complete set of octuplets set by the Chukwu octuplets of 1998. The extremely controversial circumstances of their high order multiple birth has led to debate in the field of assisted reproductive technology as well as an investigation by the Medical Board of California of the fertility specialist involved, regarding the transfer of twelve embryos at once.
