Clinical aspects in the surgical treatment of varicocele in subfertile men. II. The role of the epididymal factor

Ninety-six couples, consulting for primary or secondary infertility, and thought to be infertile due to a varicocele in the husband associated with sperm abnormalities, were subjected to a follow-up study, concluding that varicocelectomy is useful in primary infertility and unnecessary in secondary infertility.

Abstract

Ninety-six couples, consulting for primary (n = 73) or secondary (n = 23) infertility, and thought to be infertile due to a varicocele in the husband associated with sperm abnormalities, were subjected to a follow-up study. Of these, 57 were surgically corrected and 39 were not, depending only on the patient's choice. All women were intensively treated where necessary. All patients who were corrected were subjected to scrotal exploration in a search for epididymal anomalies. From our data we conclude that (1) on a statistical basis, comparing observed with expected pregnancy rates, varicocelectomy is useful in primary infertility and unnecessary in secondary infertility and (2) on an individual basis, patients with primary infertility and 'pure' varicoceles have a better prognosis than patients with concomitant epididymal dysfunction.
