Incidentally, last week's "This American Life" public radio program had some interesting segments on testosterone, and its absence/excess in various subjects. The story about the young woman who became a man, and the effect that the testosterone she was taking had on her attitudes and feelings toward others, was pretty interesting.
"Testosterone. Sure, testosterone carries some negative connotations: hyper-competitiveness, promiscuity, love of explosions, painted torsos at sporting events. Yet we all have it - men and women - and studies show that its effects are a lot stranger - and a lot more subtle - than you might think. This week, a man gets sick and loses his testosterone for four months, and his entire personality changes. A woman gets dosed with twice the testosterone men have, with some surprising effects. The pros and cons of the hormone of desire."
They have a real audio link here (scroll down a bit for last week's show):

(Apropos of another thread, they also devoted an entire show to daily life onboard the USS John C. Stennis aircraft carrier back in March, touching on some of the issues that have come up in the discussion here - when their Navy "handlers" weren't around. Just search at the above link on "aircraft carrier" or something...)
