Controlled Ovarian Stimulation

Meaning

Controlled Ovarian Stimulation (COS) is a key clinical procedure in reproductive endocrinology, involving the careful administration of exogenous gonadotropins to encourage the development of multiple ovarian follicles simultaneously. This process is precisely monitored to optimize the number and quality of oocytes available for assisted reproductive technologies, such as in vitro fertilization (IVF). The goal is to safely override the natural selection of a single dominant follicle to maximize the chances of a successful conception.
