Scrotal Thermography in Varicocele
In a cross-cultural, multicentre study on 8504 men coming to consultation as partner of an infertile couple, varicocele was found to be present in between 0% and 47% of cases with abnormal semen quality (W.H.O., 1987). This very high level of variability of varicocele frequency between different centres could not be attributed to regional differences, nor to differences in coincidental or additional causes of infertility in either the male or the female partner. The difference could only be explained by the expertise of the investigator to detect varicocele upon clinical investigation. Clearly, centres which included trained andrologists or urologists in the team of investigators reported significantly higher frequencies of varicocele than those centres lacking such team members.
