Marriage and committed romance reduce stress-related hormone production

But a piece of personal information collected before the test provided another interesting difference within the subjects. "We found that unpaired individuals of both sexes had higher cortisol levels than married individuals," Maestripieri said.

"Although marriage can be pretty stressful, it should make it easier for people to handle other stressors in their lives," Maestripieri said. "What we found is that marriage has a dampening effect on cortisol responses to psychological stress, and that is very new."

The study also found that single business school students also displayed higher baseline testosterone levels than their married or committed colleagues, a finding that mirrors previous human research as well as animal observations.

Maestripieri, who conducts the majority of his research on monkeys in Puerto Rico, said that in species of primates and birds where males assist females with rearing offspring show similar changes. In species that show monogamous pairing and shared rearing of offspring, testosterone levels in males drop as they engage in more fatherly behavior.
