This review explores ethanol sclerotherapy as a minimally invasive treatment for ovarian endometriomas in infertile women, finding it preserves ovarian function and offers comparable or improved pregnancy and IVF outcomes to cystectomy.

Abstract

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. This review examines the safety, efficacy, and impact of EST on ovarian reserve, IVF outcomes, and recurrence rates. Comparative studies suggest that pregnancy rates following EST are similar to or better than those after cystectomy, with the added benefit of more oocytes retrieved, which may lead to higher cumulative live birth rates. Despite these promising results, challenges such as recurrence and complications, particularly with prolonged ethanol exposure, remain. The use of transvaginal versus laparoscopic approaches and optimal ethanol exposure protocols are areas of ongoing research. The need for further large-scale, prospective studies is highlighted to refine the EST protocol and better understand the long-term outcomes. Sclerotherapy presents a feasible option for preserving fertility in women with endometriomas, with positive implications for IVF success and ovarian reserve preservation.
