Fertility preservation in women with endometriosis: How, when, and for whom?

Fertility preservation options, including cryopreservation of oocytes, embryos, and ovarian tissue, were initially focused on women undergoing gonadotoxic chemotherapy for oncologic treatment. The indications have expanded to include nonmalignant conditions that can also lead to follicular loss. Endometriosis is a chronic inflammatory, estrogen-dependent entity with a prevalence of 25%-50% in infertile patients. A reduction in the ovarian reserve among women with endometriosis may result either from the disease itself or from its surgical treatment. The aim of this editorial was to identify patients with endometriosis who may benefit from fertility preservation and discuss the available evidence.
