Vitamin E after varicocelectomy failed to improve sperm concentration in a meta-analysis of 408 men — the pooled effect was essentially zero (SMD 0.09, p = 0.80).

This contradicts the common belief that vitamin E reliably boosts male fertility after varicocele repair, but the evidence is still thin — only two randomized trials were pooled, and the result is a null finding, not a definitive refutation.

A meta-analysis of five studies (408 men) found that adding vitamin E after varicocelectomy — a surgery to fix enlarged veins in the scrotum — did not significantly improve sperm concentration or motility compared to surgery alone. The analysis combined just two randomized trials for the concentration measure, and the tiny effect size (0.09) with a wide confidence interval means the data are too imprecise to rule out either a small benefit or a small harm. Because this is among the first systematic reviews on this specific pairing, the picture is still unsettled, not closed.

Where this fits in the evidence

This is among the first studies we've indexed on Vitamin E for Improved Sperm Concentration — treat it as an early signal until more research accumulates.
