Methodology
Meta-analysis of observational studies and randomised trials of zinc status and supplementation on semen volume, motility and morphology.

Conclusions
Zinc supports measurable sperm quality parameters.
Limitations
Observational data dominate; heterogeneity high.
Supplements Studied
Zinc supplementation significantly increased semen volume, motility and normal morphology
Outcomes Measured
Seminal zinc was significantly lower in infertile men and zinc supplementation significantly increased semen volume, motility and normal morphology
