Abstract:
Infertile men who had 3 or more semen analyses performed in one laboratory were placed in 2 groups (I) oligozoospermic group (n = 106), mean sperm concentration between 1 and 20 million/ml (II) asthenozoospermic group (n = 71), mean sperm concentration greater than 20 million/ml, and mean motility less than 60%. With increasing durations of abstinece from ejaculation before the tests there were significant increases in semen volume and sperm concentration. Semen volume increased over the first 4 days to a similar extent in both groups. Sperm concentrations increased over 15 days, but the effect of abstinence was much greater in the asthenozoospermic group than in the oligozoospermic group (14% compared with 1.4% of the within subject variation). Significant changes in results accompanied repeated testing, notably rises in sperm concentration and motility. Sperm motility was lower in winter and higher in summer in both groups and also, but to a lesser extent, in artificial insemination donors who collected semen in the laboratory.
