Low sperm count linked to high saturated fat consumption

The cross-sectional study examined diet and semen quality for 99 men (average age 36 years) who were attending a fertility clinic. Some 71% were overweight or obese. 

The researchers found men in the highest third of total fat intake had 43% lower total sperm count and 38% lower sperm concentration than men in the lowest third. A higher intake of omega-3 fats was positively related to sperm morphology.

The authors cautioned that more research was needed.
