Although in-vitro fertilization treatment is doctor-led, many of its steps are performed by nurses. The embryo transfer step, however, is performed exclusively by doctors in the majority of units. In our unit, doctors performed embryo transfers from June 1994 until December 1995 (period I). From January 1996 until May 1997 (period II) the nurses, after appropriate training, performed the procedure. When they experienced difficulties during the mock transfer performed immediately before the real transfer, or if they were not available to do the procedure, a doctor performed it. In period I, 488 embryo transfers were performed (all by doctors), with a pregnancy rate per transfer of 35% and an implantation rate of 16%. In period II, 522 embryo transfers were performed. Nurses performed 371 (71%) and doctors 151 (29%) of the procedures. The pregnancy rate per nurse-transfer was 40.2% and per doctor-transfer 41%. The corresponding implantation rates were 16.9% and 17%. None of these differences were statistically significant (P > 0.05). These data indicate that, with appropriate training and medical back-up, nurses can perform the majority of embryo transfers with ease and outcome comparable to that of doctor embryo transfer.
尽管体外受精治疗由医生主导，但许多步骤由护士执行。然而，在大多数机构中，胚胎移植步骤仅由医生进行。在我们机构，1994年6月至1995年12月期间（第一阶段）由医生进行胚胎移植。1996年1月至1997年5月期间（第二阶段），护士在经过适当培训后执行该操作。当她们在实际移植前立即进行的模拟移植过程中遇到困难，或者她们无法进行该操作时，由医生进行移植。在第一阶段，共进行了488次胚胎移植（均由医生进行），每次移植的妊娠率为35%，着床率为16%。在第二阶段，共进行了522次胚胎移植。护士进行了371次（71%），医生进行了151次（29%）。每次护士移植的妊娠率为40.2%，每次医生移植的妊娠率为41%。相应的着床率分别为16.9%和17%。这些差异均无统计学意义（P>0.05）。这些数据表明，经过适当培训并获得医疗支持后，护士能够轻松进行大多数胚胎移植，且结果与医生进行的胚胎移植相当。
