Diet and men's fertility: does diet affect sperm quality?

Area of Science:

• Reproductive biology
• Human nutrition
• Andrology

Background:

• Male factor infertility affects a significant portion of couples seeking fertility treatment.
• Current clinical guidelines for dietary interventions in male fertility are lacking.
• Dietary patterns and specific nutrients play a crucial role in male reproductive health.

Purpose of the Study:

• To review the latest scientific evidence on the relationship between diet and male fertility in humans.
• To identify key dietary factors that support the production of healthy sperm with optimal fertility potential.
• To provide evidence-based recommendations for dietary modifications to enhance male fertility.

Main Methods:

• Systematic review of current literature on diet and human male fertility.
• Analysis of studies focusing on nutrients, dietary patterns, and sperm quality parameters.
• Synthesis of evidence regarding the impact of specific food groups and supplements on male reproductive outcomes.

Main Results:

• Antioxidant supplements show promise for men undergoing infertility treatment, though optimal types and dosages require further research.
• Increased consumption of omega-3 fatty acids from sources like fish and nuts is associated with improved male fertility.
• Dietary patterns emphasizing seafood, poultry, nuts, whole grains, fruits, and vegetables are beneficial for sperm health.

Conclusions:

• Dietary interventions, including antioxidant supplementation and specific food choices, can positively influence male fertility potential.
• Men undergoing fertility treatments may benefit from targeted nutritional strategies.
• Further research is needed to clarify specific antioxidant recommendations and dosages for male fertility enhancement.
