Is anyone surprised by this?

Research involving a group of male students found that their levels of the hormone testosterone increased to the same extent whether they were talking to a young woman they found attractive – or to one they didn’t fancy much at all.

After 300 seconds alone in the same room as a woman they had never met before, and in some cases did not find particularly attractive, the men’s testosterone levels of the hormone had shot up by an average of around eight per cent.

It reminds me of the wisdom of Billy Crystal’s character, Harry:

Sally: You’re saying I’m having sex with these men without my knowledge?
Harry: No, what I’m saying is they all want to have sex with you.
Sally: They do not.
Harry: Do too.
Sally: They do not.
Harry: Do too.
Sally: How do you know?
Harry: Because no man can be friends with a woman that he finds attractive. He always wants to have sex with her.
Sally: So you’re saying that a man can be friends with a woman he finds unattractive.
Harry: No, you pretty much want to nail them, too.
