A Risk Benefit Assessment of Drugs Used in the Treatment of Endometriosis
Progestogens and GnRH agonists can reduce endometriosis symptoms, but GnRH agonists cause bone loss, limiting long-term use without add-back therapy.

This paper reviews how hormonal medical treatments for endometriosis target the hormonal dependence of endometriotic implants, focusing on progestogens, gestrinone, and newer GnRH agonists compared in clinical trials to danazol. It reports that GnRH agonists in novel formulations significantly reduce symptoms during treatment and for 6–12 months after, with comparable improvements in R-AFS scores and fewer discontinuations than danazol, while long-term use is limited by hypoestrogenism-related bone mineral metabolism changes analogous to menopause. A stated major caveat is that there are few long-term follow-up data for gestrinone, and GnRH agonist duration is constrained until effective bone-protective add-back regimens are developed. This paper is centrally about endometriosis — it assesses the risk-benefit of drug classes (progestogens, gestrinone, and GnRH agonists) used to treat endometriosis and discusses efficacy versus limitations such as bone loss.
