Controlled Ovarian Hyperstimulation (COH): Creating more than one egg in an ovulation cycle, often used in couples with unexplained infertility.

When ovulation induction is used in women who have regular ovulations to purposely create more than one egg, it is referred to as Controlled Ovarian Hyperstimulation (COH). COH is often used in couples with unexplained infertility, in combination with Intrauterine Insemination (IUI), injection of washed sperm directly into the uterus.

COH is also used in an attempt to deliberately create multiple eggs for harvest in women undergoing IVF.
