Abstract:
A study was initiated to compare the spermiograms according to age in 570 consecutive men with a history of infertility. The semen was evaluated by computer-assisted semen analysis (CSA) and by the hyposmotic swelling test (HOS). A statistical difference was seen between men over 50 years of age compared with younger men, but only for the HOS scores and velocity. No statistical differences were found on any of the other parameters. Since most semen parameters were similar even in the men over age 50, a definite decline in fertility potential with increasing age could not be determined by this study.
