Abstract
Endometriosis is a chronic gynecological disorder characterized by ectopic endometrial-like tissue, leading to pain, dysmenorrhea, and infertility. This review explores classification systems, the mechanisms of endometriosis-related infertility, and the impact of endometriosis subtypes on fertility outcomes. Medical therapies, such as hormonal suppression, alleviate symptoms but are unsuitable for women who wish to conceive. Surgery may enhance natural conception rates in select cases but may have a negative impact on ovarian reserve. Assisted reproductive technologies, such as intrauterine insemination and in vitro fertilization, provide effective fertility treatments. However, endometriosis can negatively affect oocyte quality and implantation rates.Given the complexity of endometriosis and its varying impact on fertility, a personalized, multidisciplinary approach is recommended. This review proposes an updated treatment algorithm that integrates clinical, imaging, and other infertility causes to optimize treatment outcomes. Future research is needed for refining classification systems and indications for fertility-preservation treatments, as well as improving assisted reproductive technology success rates.
