Abstract
One possible method of studying male factors in fertility is the retrospective comparison of groups of fertile and infertile men. Such a study based on 484 fertile and 2768 infertile men showed an increased risk of infertility with decreased sperm counts and percentage of motile spermatozoa and with increased abnormal forms. The increase in relative risk is greater for the patients who consulted twice or more than for those studied for the 1st time. This difference might be explained in part by the fact that the former had a longer duration of infertility or that the couple''s infertility was less often of female origin. Consequently detailed information must be considered in fertility studies.
