Influence of the Mediterranean diet on seminal quality-a systematic review.
Plain-language summary
This systematic review set out to assess whether following a Mediterranean diet affects sperm quality in men of reproductive age. It analyzed 10 studies involving over 2,000 men aged 18-55, measuring sperm concentration and motility alongside dietary habits. Six of the ten studies found a positive link between the Mediterranean diet and better sperm health, while two found no association and two evaluated dietary patterns without clear conclusions. The review suggests that the diet's antioxidant and anti-inflammatory effects may support male reproductive health.

- 60% of studies found a positive link between the Mediterranean diet and better sperm quality.
