OK - some fun, nothing serious.
Measure your 2nd and 4th fingers on your right hand and then divide one by the other (see http://en.wikipedia.org/wiki/Digit_ratio )
The theory goes like this. Lower exposure to androgens in the womb produces a more feminine ratio - aorund 0.965 - and since we know that some studies say that TSs are caused by low androgens in the foetus resulting in incomplete masculination of the brain... well, does having a girly 2d/4d ratio correlate?
Be honest and measure properly from the midpoint of the crease between the finger and the palm to the tip of the finger (fingernails are out!!). You cannot just look at the finger because the palm is curved and each finger starts at a different 'height' if you see what I mean.
I checked both hands and got near enough the same ratio of 0.974 which puts me well above the female average so I presumably had low androgen exposure as a foetus. The male average is 0.947 so I am 0.009 ABOVE the female figure and 0.027 above the male average. The standard deviation for man is 0.029 so I am almost in the second SD which means I am in the top 20% of males with feminine hands (80% of males have a more masculine ration than me).

[edit: The BEM thing (downthread) 62%M 66%F 63%A so I am not sure what that shows
