Across 3 studies (1 beneficial, 2 neutral), Vitamin E shows mixed evidence for improving sperm morphology in men with infertility. The only beneficial effect was moderate-sized in a 2022 RCT in patients with asthenozoospermia and teratozoospermia (100 mg three times daily for 90 days), while two smaller RCTs found no significant benefit over placebo or comparator interventions. Effects are predominantly neutral, though the evidence base is too small to draw firm conclusions.
Dose: 100 mg three times daily (300 mg/day), based on the one beneficial study
