Computer assisted semen analysis not superior to routine analysis in distinguishing fertile from subfertile men

The ability of the semen analysis either by routine methods (RSA) or computer-assisted means (CSA) to predict male infertility was evaluated by determining the pregnancy rates during an 8-month span in a large group of infertile couples where a female fertility factor was identified and presumably corrected. The males were untreated. Not only was CSA less effective than RSA in predicting a male infertility factor, but also neither CSA or RSA seemed capable of identifying infertility unless severely abnormal. It would appear that there is definite need to find more accurate methods of evaluating the spermiogram.
