Prenatal testosterone synchrony in first-time parents predicts fathers' postpartum relationship quality.

ABSTRACT: There is evidence that men's testosterone levels decline across the transition to fatherhood and that this decline may reflect fathers' investment in the new family. There is also emerging evidence that cohabiting couples show synchrony or within-couple associations in testosterone levels during the perinatal period.
