title: The effect of ejaculatory frequency on semen characteristics of normozoospermic and oligozoospermic men from an infertile population.
abstract: The characteristics were examined of 87 consecutive semen samples obtained from participants of an intra-uterine insemination (IUI) programme. The population investigated comprised 65 normozoospermic, 13 moderately oligozoospermic and nine severely oligozoospermic individuals. The samples were produced after 4 days abstinence for the first IUI and after a further day of abstinence for the second IUI. Semen volume, sperm concentration, total sperm count and total motile sperm count for the whole population decreased significantly between the first and second samples. The characteristics of the second sample were significantly decreased only for the normozoospermic group.
