RESUMO
PURPOSE: Our goal was to compare serum human chorionic gonadotropin (hCG) levels in singleton pregnancies achieved following IVFET with those achieved following spontaneous conception. RESULTS: The mean serum hCG level of patients who became pregnant following IVFET lagged 1.5 days behind that of patients who became pregnant spontaneously. CONCLUSIONS: The use of gonadotropin releasing hormone analogue as part of the stimulation protocol leading to egg retrieval and IVFET results in a delay in embryo implantation.

Our study demonstrated the feasibility of using GnRH-a for triggering ovulation in women receiving hMG for ovulation induction: 11 of 13 patients had good pituitary LH and FSH surge followed by normal ovulatory P rise, and 4 became pregnant. In a selected group of patients, this method for triggering ovulation may be advantageous to using hCG.
