Human in Vitro Fertilization and Embryo Transfer

The births of more than 100 apparently normal infants at term following pregnancies initiated by in vitro fertilization and embryo transfer testifies to the successful clinical application of insights obtained from studies in reproductive biology over the last 20 years. In women, these studies have included: 1) characterization of the changes in blood hormone profiles throughout ovulatory menstrual cycles

hyaluronan (HA) using two different concentrations as embryo transfer media for in vitro fertilization embryo transfer cycles. Methods: A total of 169 cycles undergoing fresh embryo transfer on day 2 or 3, 561 cycles undergoing frozen-thawed embryo transfer on day 2 or 3, and 484 cycles of
