Notes: Follicular fluid meiosis-activating sterol (FF-MAS) is an intermediate in cholesterol biosynthesis from lanosterol (Item No. 19521) that is found at high concentrations in mammalian ovarian follicular fluid.{42473} It increases survival of human oocytes isolated from patients with polycystic ovarian syndrome (PCOS) and improves cytoplasmic maturation of immature rodent and porcine oocytes in vitro.{42474} FF-MAS promotes completion of meiotic maturation to metaphase II and increases the rate of successful in vitro fertilization (IVF) in isolated mouse oocytes.{42475} Formulations containing FF-MAS have been used to improve embryo quality and implantation rate during IVF.
