Men if your mother ate a lot of beef while she was pregnant, you could have a lower sperm count.
That is what researchers found after questioning nearly 400 men.
Researchers were not able to pinpoint a reason, including hormones, pesticides, or other chemicals in animal fat.
All of the men in the study were able to father a child without medical assistance.
So, even though sperm counts were low, the men were not infertile.
