A diet high in saturated fats may not only make it more difficult to find a partner willing to have sex with you, it may affect the quality of your sperm, according to a new study published in the journal, Human Reproduction,.
Researchers from Massachusetts General Hospital and Harvard Medical School analyzed data from 99 men with complete dietary and semen quality data were analyzed. They were primarily Caucasian (89%) with a mean (SD) age of 36.4 (5.3) years; 71% were overweight or obese; and 67% were never smokers.
In the process they discovered that a diet high in saturated fat was linked with lower sperm count and concentration.
They also found that diets high in omega-3 polyunsaturated fats, which are in fish and plant oils, were associated with better-quality semen. Basically, the sperm cells were a better size and shape.
Further, studies with larger samples are now required to confirm these findings.
