GnRH Agonist Pretreatment in Persistent Chronic Endometritis Undergoing FET

Sponsor: Guoxia Yang

View on ClinicalTrials.gov

Summary

Women with PCE represent a treatment-resistant phenotype in whom the endometrial inflammatory and immune status remains abnormal despite antibiotic therapy. GnRH agonist pretreatment may be most beneficial in endometrial phenotypes marked by persistent or residual inflammatory impairment rather than in all frozen embryo transfer populations.We therefore conducted a single-center prospective cohort study to investigate whether GnRH-HRT, compared with non-GnRH-based preparations, improve clinical pregnancy and live birth in women with PCE undergoing FET,

Interventions

DRUG

Conventional estrogen-progesterone artificial cycle for endometrial preparation

No GnRH-a down-regulation. Oral estrogen is initiated directly on early menstrual cycle, followed by progesterone transformation to prepare endometrium for FET in patients with persistent chronic endometritis.

DRUG

GnRH agonist plus estrogen-progesterone for endometrial preparation

Long-acting GnRH agonist is administered on day 2-3 of menstruation for pituitary down-regulation. After satisfactory hormonal suppression, sequential oral estrogen and progesterone are used to prepare endometrium before frozen embryo transfer in patients with persistent chronic endometritis.
