Ugly men better for babies

WOMEN wanting to get pregnant should find themselves an ugly man, new research suggests.
Scientists have found attractive males produce less sperm during sex.
Researchers think good-looking males are biologically geared to hold back their sperm in each encounter to increase their chance of impregnating more females.
But unattractive males know they are not going to bed so many females -- so when they do get lucky they give it all they've got.
The findings from the University of Oxford and University College London are backed up by studies of chickens and fish, but researchers think they could well apply to humans too.
"Human attractiveness is complicated and influenced by a number of factors including cultural preferences," said UCL researcher Sam Tazzyman.
"Nonetheless, ejaculate size and sperm quality are likely to have been moulded by similar forces, like attractiveness and the number of sexual partners, that are important in other species.
"The more attractive a male is, the more females will be willing to mate with him, reducing the value of each mating to him. This means it is optimal for him to contribute fewer sperm per mating.
"Although this reduces fertility per mating, it maximises the number of offspring he sires overall.
"Less attractive males secure fewer matings but value each of them more highly, and by allocating more sperm to each mating make the most of their meagre opportunities.
"This leads to the rather paradoxical prediction that matings with attractive males may be less fertile than those with unattractive males."

Is it just me, or does anyone else find themselves curious about the methodology used to come up with this "science"?
It would be a double-blind study perhaps. A few hundred men and women are randomly locked in a room and made to shag complete strangers, while blindfolded. The women are then tested to see who has a bun in the oven?
Or perhaps the study was done on the cheap. Unemployed graduates are hired to read the newspaper birth notices, checking out the pics of the new infants.
"Dear god", they agree, "what an ugly bunch of critters most of these babies are. Surely they are uglier than average. Eureka, I have it! ugly men must be more fertile than good looking blokes like ourselves! There's no other rational explanation. Write it up, our work here is done."
Cartoons are OK, but this proves that truth is funnier than fiction.
