Among lesbian couples anticipating their first youngster, low prenatal testosterone levels predict the next high quality of nurturing conduct, based on a brand new University of Michigan examine.
However, nearly all of testosterone analysis focuses on heterosexual samples, which limits our understanding of how these findings generalize to nonheterosexual individuals, says Kristi Chin, a U-M psychology graduate scholar and the examine’s lead writer.
Twenty-five lesbian couples between ages 18 and 45 offered saliva samples to measure testosterone every trimester throughout being pregnant and accomplished a questionnaire three months after their scheduled due date. The questionnaire assessed spousal help, division of family labor and toddler care, parenting behaviors and relationship quality.
Chin and colleagues discovered that—for each companions—lower testosterone throughout being pregnant predicted higher relationship high quality and extra time spent taking good care of the newborn.
Relationship high quality and parenting conduct additionally trusted the companion’s testosterone levels: Mothers have been extra dedicated to companions and extra overprotective of kids when their companion’s testosterone was lower.
“Our findings contribute important new knowledge about the functionality of testosterone in close relationships contexts, including some of the first evidence among sexual minorities,” Chin mentioned.
The outcomes of the examine, she says, are in keeping with prior work involving expectant heterosexual couples, which means that lower testosterone levels promotes larger caregiving and nurturance.
The examine seems in the journal Hormones and Behavior.
