title: A reassessment of comparative pregnancy and implantation rates following embryo transfer in recipients vs their infertile donors also trying to conceive in the background of performing salpingectomy for hydrosalpinx.
abstract: OBJECTIVE
  To compare pregnancy and implantation rates in egg donors trying to conceive vs their recipients in the background of salpingectomy for hydrosalpinx prior to IVF-ET.
  
  
  METHODS
  A retrospective six-year review of all donor egg cycles where the eggs are supplied by an infertile donor trying to conceive herself was carried out. Salpingectomy for hydrosalpinx was performed prior to IVF-ET.
  
  
  RESULTS
  Clinical and delivered pregnancy rates (PRs) following fresh ET were not significantly different in donors vs recipients (60.0%, 45.8% vs 56.8%, 50.8%). Implantation rates were 27.3% vs 32.6%. The respective implantation rates following frozen ET were 13.8% and 14.4%.
  
  
  CONCLUSIONS
  In the background of salpingectomy for hydrosalpinges the much higher PRs in recipients vs donors is no longer seen. The trend for higher implantation rates in recipients (about 20%) following fresh but not frozen transfer could still reflect some adverse effect of the controlled ovarian hyperstimulation regimen in a minority of women.
