Excess weight reduces men's fertility

Obese men are more likely to be infertile than their slimmer peers, according to the first study to look at whether a man's weight influences a couple's fertility (Epidemiology, Sept. 2006).
Researcher found for every excess 10 kilograms, or 20 pounds, may cut a man's fertility by 10%.
There are a number of mechanisms by which being overweight could affect fertility in males. For example, excess weight may reduce sperm concentration/count, alter hormonal balance and increase scrotal temperature, or overweight men may simply have lower libidos and less sex than normal-weight men.

Hello. I visited this site once, I commented and promised I'd be back. That was 4 months ago. I promise to visit more frequently. Anyways so this post is telling me that if I don't want kids to get fatter and if I do I should lose some weight. I guess if Im going to gain weight nows a good time =0).

I would think obese men would be less likely to have sex, period, so that would greatly reduce their chances of fertilizing an egg as well.
