title: [Clinical analysis of ultrasound-guided embryo transfer after in-vitro fertilization].
abstract: 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.
