When anthropologist Peter Gray and his colleagues measured testosterone levels of 58 men they found that levels dropped after a natural peak in the morning

AKA Morning Wood...

married men who spend time with their family have lower testosterone levels than bachelors.

Married family men are fed broccoli which has a chemical that produces estrogen-like activity. Bachelors rarely eat broccoli.

In his next project, he plans to study levels of the hormone in men separated from their wives but who have joint custody of their children to separate the impact of marriage from parenting.

Which may be followed up by the third segment of the study, in which there are plans to study the levels of the hormone in men over the age of 40 who are still living at home with their mothers to separate the impact of apron strings from marriage... ;0)

Lower levels encourage men to spend time with their family and being in a family may lower the hormone levels.

Of course, it is just possible that loving their family has something to do with behavior...nah...gotta be chemicals...

Oh, great, give 'em another excuse.

"But hillary, I can't help it that I have high testosterone levels!" Ranks right up there with "Oral sex isn't really sex."

Bring Anna Kournikovam in a room and any hetrosexual males testosterone will increase.

Don't you think the fact the single guy is constantly in the hunt that their testosterone levels are at a higher level? Behavior and mindset change your chemical balance. Kind of a chicken and egg question that can never be determined. But hey, who is to stop them from seeking more grant money.
