Significant worsening sperm parameters are associated to testicular hypotrophy in patients with a high grade...

To investigate the relationship between testicular volume and semen parameter sin patients with unilateral high grade left varicocele.

One hundred eighty seven patients who had left high grade varicocele aged 19-to-25 years were included in this study. All patients underwent a standard evaluation, including medical history and physical examination. The percentage testicular volume difference between the right and left testicles was calculated. The patients were divided into the following three groups; Group 1 (n=72) testicular volume difference <10%, testicular volume difference 10%-20% Group 2 (n=74) and testicular volume difference >20% Group 3 (n=41).

The mean age and BMI of the patients were 21.5 years and 23.1kg/m(2), respectively (P=.596, P=.943). The semen parameters and testicular volumes of the three groups were compared. The total motile sperm count, percentage of motile sperm, percentage of normal morphology sperm were found to be lower in Group 3 (P=.011, P=.012, P=.029 respectively). The mean testicular volumes for the left and the right testis were found to be 15.2cm(3) and 17.7cm(3) (P<.001), respectively. No significant difference was found in the right testicular volumes between groups (17.4, 17.7 and 18.1cm(3), P=.573).

A high grade left testicular varicocele is associated with ipsilateral testicular hypotrophy and parallel to worsened sperm parameters.
