Effect of parental age on fertilization and pregnancy characteristics in couples treated by intracytoplasmic sperm injection

1 Feb 1998

Abstract excerpt

The purpose of this study was to investigate any influence of maternal and/or paternal age on gamete characteristics and pregnancy outcomes in intracytoplasmic sperm injection (ICSI) cycles. In all, 821 consecutive ICSI cases were analysed retrospectively. While a significant linear decline in semen volume was detected, no significant differences in the concentration, motility or morphology of the spermatozoa...
