can men have excessive testosterone?!

Yes! I was tested (age 69) found low on testosterone. I started taking shots every two weeks. Then I asked for once a week. I became very frisky and horny. Then tested again. Found my level too high, My Dr. advised me to slow it down. I elected to stop as he said too much testosterone at my age could lead to the Big "C". My health being paramount-I quit the shots!

Yes,
It is possible for blood levels to stay high. It usually leads to aggression issues and a receding hair line. Balding has been linked to excess T levels. This is usually an issue for young single men in their 20's .

yes, and it does happen. overly hairy guys have more than hairless men. overly aggressive neanderthals have more than shy guys.
