Incidence of varicoceles in men with primary and secondary infertility.

OBJECTIVES: To determine whether varicoceles are more prevalent in men with secondary infertility than in men with primary infertility. METHODS: The records of 2188 consecutive men attending three infertility centers were reviewed to determine the incidence of varicoceles in men with primary and secondary infertility. In addition, other factors affecting both male and female infertility were assessed in these patients. RESULTS: The incidence of varicoceles was not significantly different between the 1447 men with primary infertility versus the 741 men with secondary infertility: 44% and 45%, respectively. The incidence of vasal agenesis was significantly greater in men with primary infertility (P < 0.001). In addition, the female partner was significantly older in couples with secondary infertility (P < 0.001). CONCLUSIONS: These findings do not support the conclusion that varicoceles have a progressive adverse effect on fertility over time and suggest that further study is needed to determine whether varicocele repair is indicated in patients with normal semen parameters.
