Ethanol Sclerotherapy for Endometriomas in Infertile Women: A Narrative Review.

Ethanol sclerotherapy (EST) has gained attention as a minimally invasive treatment option for ovarian endometriomas, particularly in infertile women with endometrioma undergoing in vitro fertilization (IVF). Endometriomas are associated with decreased ovarian reserve and impaired fertility outcomes, and traditional surgical approaches, such as cystectomy, often lead to further reductions in ovarian reserve. Ethanol sclerotherapy offers a potential alternative that preserves ovarian function while effectively managing endometriomas.
