结局指标
主要结局
Clinical pregnancy
时间窗: 3 weeks after Embryo transfer
A clinical pregnancy is a pregnancy that is confirmed by ultrasonic visualization of gestational sac or heartbeat.
次要结局
- Degree of cramping and pain(During and immediately after ET)
- Endometrial visualization at time of embryo transfer(During ET)
- Time required for ET(Time from when the catheter is handed to the transferring physician to the time it is returned to the transferring embryologist.)
