Fertility and sterility
-
One hundred men with proven fertility who presented for vasectomy consultation were examined for testicular size and presence of a varicocele, including examination with the Doppler stethoscope for the presence of subclinical varicocele. A diagnosis of varicocele was established in 61%. ⋯ It is apparent that varicoceles, especially subclinical varicoceles, are an extremely common finding, even in a group of fertile men. The results suggest that subclinical varicoceles have no role in male infertility.
