How do you knock down the testosterone in men? Have a baby.
Researchers at UW-Madison have discovered that the scent of a newborn marmoset, a type of monkey, can alter the testosterone level in papa marmoset, making for a calmer, more relaxed dad, which can help in the parenting of the baby marmosets.
The discovery was announced Wednesday by the Wisconsin National Primate Research Center and is published in the Sept. 2 issue of the journal Biology Letters.
