Ovarian suppression can be used for several reasons. It is commonly employed in the treatment of hormone receptor-positive breast cancer in premenopausal women to reduce the risk of recurrence. It is also used in the management of endometriosis, a condition where tissue similar to the endometrium grows outside the uterus, causing pain and infertility. Additionally, ovarian suppression is sometimes used in assisted reproductive technology (ART) to control the timing of the ovarian cycle.
