OBJECTIVE: To evaluate the seminal, hormonal, and spontaneous pregnancy outcome after percutaneous embolization of the internal spermatic vein in infertile men with left-sided subclinical varicocele and one or more abnormal semen parameters.
METHODS: A total of 218 patients underwent percutaneous embolization, and 119 patients were included as the observation group. All patients were followed up prospectively for 39.4 ± 6.5 months. Semen parameters and hormonal levels were evaluated before any procedure and 6 months after.
RESULTS: Significant improvement in the mean sperm concentration, total motility, and lower follicle-stimulating hormone levels was noted in those who underwent varicocele embolization as compared with those not treated. After 39.4 ± 6.5 months, pregnancy rates were 46.3% for the treated group and 11.8% for the control group (P = .011).
CONCLUSION: In infertile men, small varicoceles, even subclinical ones, should be identified and treated.
