Abstract
Outpatients (57) presented for the 1st time in 1975-1978 and a 2nd time 4 yr later (1979-1982). Both semen analyses were compared with respect to the year of the 1st examination. Significant variations of seminal parameters with increasing age were not found, but sperm count and rate of abnormal sperm was significantly higher in the years 1975-1978 than in 1979-1982 at the 2nd visit. Individual patients showed, despite the fairly constant mean values, marked variations of sperm count from one analysis to the next.Keywords
