Wow. Amazing sample size of 18.
This particular study isn't very convincing, but there's no doubt in my mind that homosexuals of both sexes have very different physiologies on average. Take a look at the typical bull dyke and try telling me that there aren't high doses of testosterone there or that some of the body proportions (hip/shoulder ratios) aren't more like a man's.
Very true. Statistically, nothing at all.
Of course, people who “report” things like this in the media know less than nothing about statistics.
