Male factor infertility accounts for approximately 30–40% of fertility challenges. Diet profoundly influences sperm quality, motility, and count — and keto may offer significant benefits.
Insulin resistance disrupts testosterone production and impairs sperm quality. High insulin elevates SHBG (sex hormone binding globulin), reducing bioavailable testosterone.
By dramatically reducing insulin levels, keto increases free testosterone availability. Multiple studies show that weight loss combined with low-carb eating improves testosterone in overweight men.
Sperm DNA is uniquely vulnerable to oxidative damage. Keto’s anti-inflammatory and antioxidant effects — from omega-3s, zinc, selenium, and reduced oxidative stress — may protect sperm DNA integrity.
Obesity is directly associated with reduced sperm count and motility. The visceral fat reduction keto produces improves hormonal balance and sperm parameters.
Oysters (zinc), fatty fish (omega-3 and vitamin D), Brazil nuts (selenium), and eggs (CoQ10) are all fertility-supportive. Find them in our keto main dishes and keto breakfast collection.
