title: Effects of hydrosalpinx on ultrasonographic parameters for endometrial receptivity during the window of implantation measured by power color Doppler ultrasound.
abstract: OBJECTIVE
  The aim of this study is to assess the effects of hydrosalpinx on ultrasonographic parameters for endometrial receptivity during the window of implantation, as measured by power color Doppler ultrasound.
  
  
  METHODS
  The women recruited to this study included sixty with unilateral or bilateral hydrosalpinx and fifty-seven prior to in vitro fertilization-embryo transfer (IVF-ET) or artificial insemination (AI) performed due to male infertility. Ultrasonographic parameters for endometrial receptivity were measured during the window of implantation by power color Doppler ultrasound.
  
  
  RESULTS
  The proportion of triple-line endometrial pattern and uterine contractions from the cervix to the fundus were significantly lower in the hydrosalpinx group than in the control group. In addition, patients in the hydrosalpinx group had a significantly lower pulsatility index (PI) of uterine spiral arteries. There were no significant differences in endometrial thickness, subendometrial blood flow distribution pattern, uterine artery PI, uterine artery resistance index (RI), or uterine spiral artery RI between the two groups.
  
  
  CONCLUSIONS
  Hydrosalpinx may be involved in the regulation of endometrial receptivity through its influence on endometrial pattern, uterine contractions, and PI of the uterine spiral arteries.
