摘要: AbstractPurpose: To compare the clinical result of mini-dose GnRH-a long protocol with short in older patients undergoing IVF.Materials and methods: This was a retrospective study. Four hundred sixty-one women aged above 35-year-old first cycle were assigned to two groups: (n = 359); (n = 102). Both groups divided based on their age, into over under 38 years old. Primary outcome include live birth rate per started cycle. Other outcomes good-quality embryo rate, pregnancy rate.Results: Patients treated those showed similar rate. In group 35–38 old, significantly thicker endometrium at day hCG administration, higher number good embryos obtained (56.3% versus 46.5%) compared protocol. The implantation clini...
