Saturated Fats Tied to Lower Sperm Counts in Danish Study

Saturated fats, which are found in cheeses and meats, are being blamed for falling sperm counts among Danish men in a new study.  More from Reuters:

Researchers, whose report appeared in The American Journal of Clinical Nutrition, found that young Danish men who ate the most saturated fats had a 38 percent lower concentration of sperm, and 41 percent lower sperm counts in their semen, than those who ate the least fat.

“We cannot say that it has a causal effect, but I think other studies have shown that saturated fat intake has shown a connection to other problems and now also for sperm count,” said Tina Jensen, the study’s lead author from Rigshospitalet in Copenhagen, the Danish capital.

The research is not the first to connect diet and other lifestyle factors to sperm production and quality. In 2011, Brazilian researchers found that men who ate more fruit and grains suchs wheat, oats or barley had faster and more agile sperm, as well as more sperm overall.

But that study and most others looked at these associations using data on men seeking fertility treatments, which may not be representative of all men.
