Objective:
To investigate whether ultrasound (US) guided embryo transfer could improve pregnancy rates.
Methods:
A prospective randomized trial was conducted to compare embryo transfer under abdominal US guidance (n = 178) with traditional embryo transfer (n = 152).
Results:
The clinical pregnancy rate was 37.1% (66/178) in the US group compared with 25.0% (38/152) in the traditional group (P < 0.05).
Conclusions:
US guided embryo transfer after in vitro fertilization increased pregnancy and implantation rates. It is suggested that embryo transfer should be performed under ultrasound guidance.
