title: Artificial endometrial preparation for oocyte donation using synthetic estrogen and progestogen.
abstract: OBJECTIVE
  To evaluate the outcome of an oocyte donation program using synthetic estrogen and progestational agents for uterine preparation.
  
  
  METHODS
  Conjugated estrogen, 1.25 mg per day at increasing doses and dydrogesterone, a synthetic progestogen, 30 mg per day were used for uterine priming. All embryo transfers were done on day 2 of progestogen supplementation.
  
  
  RESULTS
  The pregnancy rates were 38% per embryo transfer. The ongoing pregnancy rate was 31% with an abortion rate of 20%.
  
  
  CONCLUSIONS
  Endometrial preparation in an oocyte donation program using orally administered synthetic estrogen and progestogen gives pregnancy rates comparable to those reported with natural products.
