Sex differences in prolactin change during mourning.

Fourteen men and 12 women were interviewed eight weeks after conjugal bereavement to discuss the events prior to the spouse's death and the subsequent bereavement period. Prolactin (PRL) was measured at the beginning and end of the interview. Descriptions of the deceased spouse were obtained during the interview and rated for Developmental Level of Object Representation (DLOR), a measure of the cognitive complexity of the description. There were significant correlations between DLOR and PRL change for both men and women but the correlation for women was positive and the correlation for men was negative. These findings extend the literature on the psychological correlates of PRL change and suggest that the physiological changes associated with mourning are different for men and women.
