New Harvard's Study shows that Bacon may harm male fertility
Researchers from Harvard University published a study. Study shows that eating too much processed meat was associated with lower semen quality in men. The study has been presented by researchers from the Harvard School of Public Health. At the 2013 American Society for Reproductive Medicine conference.
They found out that men who ate half a portion of processed meat a day had 5.5 % ‘normal’ shaped sperm cells, compared to 7.2 % who ate less.
But the study also noted a positive association between male fertility and fish consumption. White meat fish is associated with a higher percentage of normal sperm. Salmon, tuna and other dark meat fish, on the other hand, are related to a higher total sperm count.
