Clinical observations on fertile males with varicocele.

During the clinical observation of 32 fertile cases with varicocele interesting findings were made. Normal semen, a sperm density above 40 million/ml and a motile sperm rate of over 60% were observed in 46.9% of the cases. Furthermore, a sperm density of more than 40 million/ml was found in 75% and a motile sperm rate of more than 50% was detected in 81.3%, indicating normal or adequate spermogram data. A difference in right-left testicular size was recognized in 35.5% (11 cases). Only 2 of the cases had oligospermia and 9 cases had normospermia. Two cases had low testosterone values and low motile sperm rates were also detected. Secondary infertility occurred in 33.3%. In 25% of the cases, scrotal scintigraphy revealed an accumulation of high radioactivity indicating venous blood pooling over the affected site in the early phase of dynamic images. In the other cases, different venous flow characteristics were detected visually.
