Se, marriage and testosterone

[Guest guest]

Hi All,

The below may be of interest regarding the role of testosterone levels and

marital/dating status, which are reduced with CR.

A team led by Gray, a biological anthropologist at the University of

Nevada,

Las Vegas, recruited 66 bachelors, 30 married men without children, and 30

married

fathers aged 21 to 38 in Beijing who twice a day provided saliva for testing.

Compared with bachelors, childless husbands had about 20% lower levels of the

hormone in the morning (when levels are highest), and married fathers had almost

50%

lower levels. Smaller but significant differences showed up in afternoon

measurements, the team reported last week in Proceedings of the Royal Society:

B.

Psychologist Nick Neave of Northumbria University in Newcastle-upon-Tyne says

the

findings make sense because testosterone is related to " a host of sexual

behaviors

intended to attract a mate [but which] are not conducive to marital bliss and

especially not when very young children are present. " He adds: " It would be

interesting to see if testosterone levels are associated with poorer male

parenting

skills. "
