Abstract：
Pregnancy after an embryo transfer depends largely on embryo quality, endometrial receptivity, and the technique used in the embryo transfer. Embryo transfers have been reported as inevitably traumatic and difficult for 5-7% of patients in assisted reproduction treatment. In these cases, transmyometrial embryo transfer should be considered as a suitable method to overcome difficult embryo transfers. The aim of this study was to report our experience with this technique and analyze its causes, results and complications.
Since 1993, 39 women (40 cycles of assisted reproductive technology treatment) were submitted to transmyometrial embryo transfers in our center. The procedures were carried out as described by the Towako group.
The enrolled female patients had a mean age of 34 years and a mean baseline FSH level of 6.89 IU/mL. The median number of retrieved oocytes was 7.50 and a mean of 2.63 embryos were transferred. Implantation rate was 9.5%. With respect to clinical results, pregnancy and miscarriage rates were 25% and 30%, respectively. Since there were two twin pregnancies, the live birth rate was 22.5% (9/40). No major complications were reported.
Transmyometrial embryo transfer can and should be an option in cases of difficult/impossible transcervical embryo transfer.

摘要：
胚胎移植后的妊娠很大程度上取决于胚胎质量。子宫内膜容受性，以及胚胎移植中使用的技术。据报道，胚胎移植对于5-7％的辅助生殖治疗患者来说是不可避免的创伤和困难。在这些情况下,经子宫肌层胚胎移植应被视为克服胚胎移植困难的合适方法.这项研究的目的是报告我们使用这种技术的经验并分析其原因，结果和并发症。
自1993年以来，我们中心有39名妇女（40个辅助生殖技术治疗周期）接受了子宫肌层胚胎移植。该程序如Towako小组所述进行。
入选女性患者的平均年龄为34岁，平均基线FSH水平为6.89IU/mL。回收的卵母细胞的中位数为7.50，平均转移了2.63个胚胎。种植率为9.5%。关于临床结果，妊娠率和流产率分别为25%和30%，分别。因为有两次双胞胎怀孕，活产率为22.5%(9/40)。无重大并发症报告。
在困难/不可能的经子宫颈胚胎移植的情况下，经肌层胚胎移植可以而且应该是一种选择。
