A retrospective analysis of fresh in vitro fertilization treatment cycles and frozen embryo transfer (FET) cycles from mid-1995 to December 31, 1998, was undertaken. Nurses performed embryo transfer (ET) for government-funded cycles, whereas doctors performed ET for self-funded cycles. During the study period, fresh ET was performed in 1,165 treatment cycles. There were no significant differences in demographic data, ovarian responses and the number of embryos replaced between ET cycles performed by nurses and doctors. Pregnancy rates for ETs performed by nurses and doctors were 16.7 and 15.8% per transfer, respectively, whereas the corresponding implantation rates were 8.3 and 6.9%, respectively. Similar pregnancy and implantation rates were encountered in FET cycles whether ET was performed by nurses or doctors.
对1995年年中至1998年12月31日期间的新鲜体外受精治疗周期和冷冻胚胎移植（FET）周期进行了回顾性分析。护士为政府资助的周期进行胚胎移植（ET），而医生为自费周期进行ET。在研究期间，1165个治疗周期进行了新鲜ET。护士和医生进行的ET周期在人口统计学数据、卵巢反应和移植胚胎数量方面无显著差异。护士和医生进行的ET每次移植的妊娠率分别为16.7%和15.8%，而相应的着床率分别为8.3%和6.9%。无论ET是由护士还是医生进行，FET周期中的妊娠率和着床率相似。
