本研究包括1983年以来Duke大学医学中心行IVF-ET登记的全部夫妇,登记前全面复习妇科病史,对过去调查批评性地进行评价以保证不遗漏其他治疗。体外受精和胚胎输送(IVF-ET)治疗的标准,夫妇至少试图妊娠2年,进行了所有其他有效治疗但未成功,夫妇确实较长时间未孕,在IVFET周期给予CC和hMG或单用hCG。本文复习的是非ET周期发生的临床妊娠,分为3类,(1)与治疗无关的自然妊娠,登记后等待IVF-ET周期期间或尝试IVF-ET后发生的妊娠。(2)与治疗相关的妊娠,在因卵泡反应差或检测自然LH峰波取消回收卵细胞的IVF-ET周期
This study included all couples registered with the IVF-ET at the Duke University Medical Center since 1983, a comprehensive review of the history of gynecology before enrollment, and a critical review of past investigations to ensure that no other treatment is missed. In vitro fertilization and embryo transfer (IVF-ET) treatment criteria, the couple tried at least 2 years of pregnancy, all other effective treatment but did not succeed, the couple did not pregnancy for a long time, in the IVFET cycle given CC and hMG or hCG alone . This review reviews clinical pregnancies that occur in non-ET cycles and are categorized into three categories, (1) natural pregnancies unrelated to treatment, and registration of pregnancies that occur after the IVF-ET cycle or IVF-ET trial. (2) treatment-related pregnancies, abrogating IVF-ET cycles of egg recovery due to poor follicular response or detection of natural LH wave
