This study compared IVF outcomes in endometriosis patients using antagonist, long agonist, or prolonged agonist protocols, finding the antagonist protocol comparable to agonist protocols, especially for diminished ovarian reserve.

The paper discusses controlled ovarian stimulation protocols in endometriosis patients, comparing outcomes under antagonist versus agonist approaches for ovarian stimulation. It addresses which protocol is preferable in this patient population, presenting the comparative findings reported in the underlying clinical context. A major limitation explicitly reflected in the presentation is that the article content shown in the provided text is largely administrative and does not include detailed methods, results, or a stated evidence-based limitation. This paper is centrally about endometriosis — it focuses on how antagonist versus agonist controlled ovarian stimulation protocols are managed and compared in endometriosis patients.

Abstract

OBJECTIVE: fertilization-embryo transfer (IVF-ET) in patients with endometriosis using antagonist protocol, long agonist protocol or prolonged agonist protocol. METHODS: Totally 313 patients with endometriosis were recruited in Reproductive Centers of the Second Affiliated Hospital of Zhejiang University School of Medicine,Jiaxing Women and Children's Hospital,and Ningbo Women and Children's Hospital from April 2017 to October 2018, including 81 patients treated with antagonist protocol (antagonist group), 148 treated with long agonist protocol (long agonist group) and 84 treated with prolonged agonist protocol (prolonged agonist group). The clinical and laboratory data of the patients were retrospectively analyzed to investigate the effect of ovarian stimulation protocols on the IVF-ET outcomes of patients with endometriosis. RESULTS: <0.05). CONCLUSIONS: Patients with endometriosis who used the antagonist protocol in IVF procedure could reduce the cost and time of Gn treatment, when combined with frozen-embryo transfer strategy the antagonist protocol has comparable clinical pregnancy outcome with long or prolonged agonist protocol, especially in those with diminished ovarian reserve, the higher available embryo rate can be achieved.
