Will milk increase sperm count?

Low-fat dairy intake was positively related to sperm concentration and progressive motility. On average, men in the highest quartile of intake (1.22–3.54 servings/day) had 33% (95% confidence interval (CI) 1, 55) higher sperm concentration and 9.3 (95%CI 1.4, 17.2) percentage units higher sperm motility than men in the lowest quartile of intake (≤0.28 servings/day). These associations were primarily explained by intake of low-fat milk. The corresponding results for low-fat milk were 30% (95%CI 1,51) higher sperm concentration and 8.7 (95%CI 3.0, 14.4) percentage units higher sperm motility. Cheese intake was associated with lower sperm concentration among ever smokers. In this group, men in the highest tertile of intake (0.82–2.43 servings/day) had 53.2% (95%CI 9.7, 75.7) lower sperm concentration than men in the lowest tertile of cheese intake (<0.43 servings/day).
