The research in question analysed the diets of 99 men who were attending a fertility clinic in the US, and found that those who ate diets that were high in junk food were more likely to have poorer sperm quality.
The research team was led by Professor Jill Attaman from Harvard Medical School in Boston, and involved questioning the study participants about their diet, as well as analysing their sperm over a four-year period.
The results of the study showed that the men who consumed the highest amount of fat had a sperm count which was 43% lower on average with the men eating the least fat. In addition, the men eating the most fat also had a far lower sperm concentration.
“The magnitude of the association is quite dramatic and provides further support for the health efforts to limit consumption of saturated fat given their relation with other health outcomes such as cardiovascular disease.” Said Prof Attaman.
