BACKGROUND: GnRH agonist and antagonist were developed to control the premature release of LH surge. There is some difference between two protocols. OBJECTIVE: We compared the outcome of frozen-thawed embryo transfer in infertile women who…

BACKGROUND: Human chorionic gonadotropin (HCG) has been used as a replacement for the mid-cycle luteinizing hormone (LH) surge for several years. The recent arrival of recombinant DNA technology has made recombinant HCG (rHCG) accessible. …
