Too much soy reduces sperm count

Washington: Eating or drinking a lot of products containing soy and isoflavones can result in reduced sperm count among men, a Harvard School of Public Health study has shown.
"There has been a lot of interest on whether soy affects fertility because many studies in animals suggest that this is the case, but there are very few studies in humans," said researcher and lead study author Jorge Chavarro.
"This only the third study to look at whether soy food has a relationship with fertility in humans and the first one to find an association in agreement to the animal studies," he said.
Soy contains isoflavones, an organic compound which acts like female hormones and appears to impede a man's ability to produce sperm.
The Harvard study examined the soy intake of 99 men, determined to be part of couples experiencing fertility difficulties, over the course of three months. -AFP (Source: The Star)

Interesting article I ran into few days ago. So guys watch out. But for the girls, soy is an excellent source of protein and the female reproductive hormone estrogen. Soy foods contain phytoestrogens, literally meaning plant-derived estrogen. The type of phytoestrogen in soy is known as isoflavones. Evidence is growing that these phytoestrogens may help with menopausal symptoms, as well as inhibits cancer cell growth.
