K-Fed sperminates again! Why some guys are super-fertile...

3 women, 5 kids, and all before he's 33. Say what you will about Kevin Federline, the man is a stud. In farmer's speak, that is.

Britney Spears' ex is about to be a dad again, this time with his long-term girlfriend Victoria Prince. Both Britney and Shar Jackson already have two kids with the stallion. His new child, expected to arrive in about four months, will have three half brothers, one half sister and two semi-moms.

Here's a question: does he practice incessant, hourly unsafe sex or he is simply more fertile than other men? Based on the guidelines for male fertility, K-Fed's lifestyle doesn't lend itself to so much baby-making. Drinking, smoking, weight gain, are all major deterrents in sperm productivity. He is still under 35, the age male fertility drops dramatically, but so are a lot of other men who can safely look at a woman without putting a baby in her body. So why is K-Fed, a man who struggles with the role of devoted provider and partner, so prone to being a dad?

Ask chickens. A group of Oxford University researchers found that dominant male versions of the species had less productive sperm than subservient males. In other words, the alpha-males couldn't make baby chicks as prodigiously as the lazy male chickens. The higher the social status of a male chicken, the lower his sperm quality, and vice versa.

The takeaway: the less appealing and productive the guy, the more likely he is to get you pregnant. Great, thanks, mother nature. Whose team are you on anyway?
