Semen analysis: a review of samples from 225 men seen at an infertility clinic.

The results from 225 men attending an infertility clinic are presented. The percentage of oval, viable and active sperm cells, and the motility scores were lower in samples with counts less than 10 times 10(6) per ml., increased in counts or 10 to 40 times 10(6) per ml. and again increased in counts more than 40 times 10(6) per ml. The percentage of semen samples with abnormalities in measured parameters dramatically increased as the sperm count decreased. The percentage of samples with significant numbers of white blood cells was higher in samples with sperm counts less than 10 times 10(6) per ml. and in the azoospermic patients, while viscosity problems seemed to be associated with counts less than 10 times 10(6) per ml. Agglutination was more of a problem in samples with counts more than 40 times 10(6) per ml.
