Endometriosis is a painful condition where tissue similar to the uterine lining grows outside the uterus, driven by hormone imbalances and inflammation. It causes menstrual pain, infertility, and can affect other organs. Hormone medicines—including GnRH analogs like gonadorelin—can shut down periods and ease pain, but treatment usually needs a team of doctors because the disease is complex.

Endometriosis is a chronic gynecologic disease of reproductive-age women, causing menstrual pain and infertility. Endocrine and inflammatory mechanisms drive its development, with estrogen/progesterone imbalance contributing to extrauterine implantation and persistence of ectopic endometrial cells. Chronic pain also induces stress-related disorders, worsening the quality of life. Infertility results from inflammatory, ovarian, and endometrial changes, and adverse pregnancy outcomes are reported. Diagnosis of endometriosis is clinical and imaging based. Furthermore, gastrointestinal, urinary, or autoimmune comorbidities complicate endometriosis management. Hormonal treatments, including progestins, estro-progestins, gonadotropin-releasing hormone analogs (GnRH-a), or oral antagonists, suppress menstruation and relieve pain. The relevant endocrine aspects and the systemic comorbidities make endometriosis a syndrome that requires a multidisciplinary diagnostic and therapeutic approach.
