See, this is one of the frustrations of science. No, NOT that good looking men don't ejaculate as much sperm as previously thought. Its frustrating that you do your research and think you have a good grasp of a concept and then a new study comes out and blows the old one away.
The old school of thought was that "alpha males," the tallest, best looking and healthiest men, produced more sperm than average guys and had a better chance of getting a woman pregnant. According to a study released last year, that's wrong. The study was done at Oxford University and University College London and found that attractive men ejaculated less sperm per sexual encounter than unattractive men.
Still, that doesn't mean that they are of less quality, reproductively speaking. Just the opposite. Its possible that on a subconscious level, good looking men know that they will be bedding more women than other men will and save their sperm for all of them. Less attractive men work on a similar subconscious level. They have larger sperm concentrations, because they may not get another chance to pass on their genes.
Much of this train of thought comes from studies of chicken and bird sperm counts, but scientists say that the same may be true of human beings. My job may suck, but at least I'm not a chicken sperm collector.
