Relationship between testicular volume and presence of varicocele. A comparative study.
The varicocele, present in many of the male partners of infertile couples continues to generate controversy, particularly as related to its diagnosis and pathophysiology. The purpose of our study was to determine the relationship between testicular volume and the presence or absence of a varicocele. Testicular volume was determined by the use of an orchiometer; the presence of a varicocele was determined by palpation during a Valsalva maneuver. The patients utilized in the study were those seen in our Andrology and General Urology Clinics; 291 patients with varicoceles and 83 control patients (no evidence of varicocele) were used. The left (mean = 21.4 mL) and right (mean = 23.4 mL) testicular volumes of patients with a varicocele were significantly reduced compared with that of the control group (left, mean = 23.4 mL; right, mean = 26.2 mL; p = 0.0041 and p = 0.002, respectively). The testicular volume corrected on the basis of the body mass (V/m2) also was significantly reduced in the varicocele group compared with controls (left p = 0.007; right p = 0.001). Reduced testicular volume relative to body size may be detected prior to actual demonstration of the stress pattern and the presence of a varicocele, and may be useful in early diagnosis. It is suggested that measurement of testicular volume may be a useful adjunct to routine examination of the infertile male.
