New mothers' senses are definitely heightened, likely thanks to greater amounts of the stress hormone cortisol, says Robin Edelstein, Ph.D., professor of psychology at the University of Michigan. Cortisol levels increase quite a bit during pregnancy and stay somewhat elevated postpartum, which may help women be attentive to their infants, says Edelstein.

"The previous studies have shown that men with children have lower testosterone than men who don't have children," said Robin Edelstein, who led the new study.
Her team's results are the first to show those hormonal changes might actually begin early in the pregnancy, said Edelstein, a psychologist and director of the Personality, Relationships, and Hormones lab at the University of Michigan in Ann Arbor.
"That's what I think is interesting - that it's not about having the baby there (physically) but that there may be some process happening even when just thinking about becoming a father," she said.
For their study, published in the American Journal of Human Biology, Edelstein and her colleagues enrolled 29 couples who were expecting their first babies.
Edelstein said the study team isn't sure why these hormone levels were closely correlated in couples, but it might be due to pregnancy being both an exciting and stressful experience that's shared by both parents.
"That's something we would like to look at a little more," she said. "It might suggest there is some kind of interdependence or something going on between the partners that is reflected in the correlated hormone levels."
Edelstein said the study team has also looked at data taken from some of the fathers after their babies were born. She said it appears that men who had larger declines in testosterone have reported being more engaged with their infants and more supportive of their spouses.
"This suggests that there's some kind of benefit to these changes, that there may be something that's helpful about having declines in testosterone," she said.

"There are hormonal changes going on with men as well, and they occur earlier than other studies have suggested," said lead researcher Robin Edelstein, an associate professor of psychology at the University of Michigan, Ann Arbor.
"What we found is there is a gradual decline in men's testosterone," she said. The study was published online Dec. 15 in the American Journal of Human Biology.
Edelstein and her team followed 29 expectant heterosexual couples, all expecting their first child together. They looked at four different times throughout the pregnancy, evaluating salivary testosterone, cortisol, estradiol and progesterone. They looked at the levels of those hormones at weeks 12, 20, 28 and 36.
As expected, levels of all four of the hormones increased in women. (Women's testosterone declines after birth.) Meanwhile, men showed substantial declines in levels of both testosterone and estradiol but showed no changes in levels of cortisol or progesterone.
Edelstein said few studies have looked at whether men might show hormonal changes as their partner proceeds through pregnancy.
She can't explain why the hormones change as they do in men, or what effect that might have. "That is something we are really interested in," she said. "It's something we can look at, but we haven't yet."
One idea, she said, is that men with lower testosterone might be better caregivers, as they would be less aggressive.
The changes detected, she said, "are very small," and were not enough to be considered low-testosterone.
The change might be about psychologically preparing to be a father, Edelstein speculated.

The new U-M study is the first to show that the decline may begin even earlier, during the transition to fatherhood, said Robin Edelstein, the study's lead author.
"We don't yet know exactly why men's hormones are changing," said Edelstein, U-M associate professor of psychology.
Edelstein and colleagues examined salivary testosterone, cortisol, estradiol and progesterone in 29 first-time expectant couples between the ages of 18 and 45. The saliva samples were obtained up to four times during the prenatal period at about 12, 20, 28 and 36 weeks of pregnancy.
Women showed large prenatal increases in all four hormones, while men saw declines in testosterone (which is associated with aggression and parental care) and estradiol (which is associated with caregiving and bonding). No changes were found in men's cortisol (a stress hormone) or progesterone (which is associated with social closeness and maternal behavior).
So it's not just about the presence of an infant that lowers testosterone, Edelstein said.
One limitation of the new study--as it relates to lower testosterone--is that researchers do not have a comparison group of men who are not expecting a child.
"Thus, we can't completely rule out the possibility that the changes are simply due to age or the passage of time," Edelstein said.
