An analysis of 581 in-vitro fertilization treatment cycles was carried out to determine the pattern of utilization of retrieved oocytes. Patients were divided into five groups depending on the number of retrieved oocytes. The mean fertilization rate of 57% was broadly similar amongst the groups but the proportion of retrieved oocytes that produced embryos of a quality suitable for transfer or cryopreservation (the cycle efficiency index) fell significantly with increase in the retrieved oocyte… CONTINUE READING
