title: The use of surrogate gestational carriers for assisted reproductive technologies.
abstract: OBJECTIVE
  We determined the effect of embryo transfer, zygote intrafallopian transfer, and frozen embryo transfer on clinical outcomes after surrogate gestational transfers.
  
  
  METHODS
  Prospective randomization was carried out.
  
  
  RESULTS
  Forty-five infertile couples were matched with a gestational surrogate carrier and underwent 81 cycles of embryo transfer with various assisted reproductive technologic procedures. Nineteen cycles produced a clinical pregnancy, with delivery in 15 of 81 cycles (18.5% live-birth rate). Fifteen of the 45 couples (33%) had a child from the surrogate gestational carrier program.
  
  
  CONCLUSIONS
  No significant differences in clinical outcome were observed on the basis of the type of procedure performed or the age of the patient.
