Abstract
PURPOSE: The aim of this study was to investigate whether the hCG-oocyte collection interval has any influence on the oocyte recovery rate, fertilization rate, and outcome of IVF-ET cycles. METHODS:Five hundred thirty-three consecutive patients undergoing their first IVF-ET treatment cycle at King's Assisted Conception Unit between 1993 and 1995 were included in this study. RESULTS: There was no significant difference in the oocyte recovery rates, fertilization rates, or outcome of IVF-ET treatment among the hCG-oocyte collection intervals examined (33-41 hr). None of the 533 women studied had ovulated before oocyte collection. CONCLUSIONS: The results do not suggest a trend toward increased ovulation more than 36 hr after hCG administration.
