摘要: Objective To compare the reproductive outcome of three protocols for frozen ET treatment. Design Retrospective follow-up study. Setting Two public clinics and one private clinic. Patient(s) Four thousand four hundred seventy cycles between 2006 and 2010. Intervention(s) Thawing embryos ET. Main Outcome Measure(s) Pregnancy test rate, clinical pregnancy loss rate. Result(s) The natural cycle followed by P (NC + P) was used in 26% cycles, with hCG hCG) 10%, substituted estrogen (E 64% cycles. rate transfers after thawing similar all groups (87.2%, 73.9%, 87.2%, respectively). There a significantly higher positive E (34.3%) NC (35.5%) as compared (26.7%). However, (27.7%, 29.1%, 24.3%, Moreover, no differences were seen regarding live-birth (20.1%, 23.5%, 20.7%, A logistic regression analysis showed that type protocol only predictor loss, while age, irregular endometrial thickness, number, quality transferred did not correlate to loss. Conclusion(s) obtained comparison other protocols; however, due an increased preclinical comparable pregnancy, delivery rates are reported protocols.
