Ovulation induction refers to assisting a woman, who does not regularly ovulate,  to ovulate one egg.  This is achieved with fertility pills (e.g. clomiphene citrate or letrozole) or injectable medications (gonadotropins).  The latter requires monitoring with bloodwork and ultrasound every 2-3 days over a 2-week period.   The approach depends on the patient’s medical history.  It may / may not be combined with intrauterine insemination (IUI).

Superovulation refers to increasing the number of eggs that are ovulating (from one to more than one) to increase the probability of pregnancy.  The number of eggs targeted depends on the woman’s age. This can be achieved also with fertility pills or injectable medications but is always combined with IUI.  The timing for IUI may be determined by ovulation kits or bloodwork and ultrasound monitoring.  The approach, medication type and dose is determined by the patient’s medical history and age.
