Abstract

OBJECTIVE
To investigate the effect of profound LH suppression in the late follicular phase during controlled ovarian hyperstimulation (COH) on pregnancy rate. METHODS: Data were collected by retrospective analysis. A total of 172 cycles of oocytes retrieval for IVF after COH with GnRH agonist-down regulation and hMG/FSH were included from January 1999 to July 2002. Serum LH, FSH, estradiol and progesterone concentrations were measured on the day 3 of the preceding cycle and LH concentration was measured on the day of hCG administration. Based on LH concentrations (mIU/mL) on the day of hCG administration, cycles are classfied to two groups (group 1: LH>0.7 mIU/mL, group 2: LH
