Masculinity, however, can

come at a high price. Women often think of high-testosterone types as uncooperative, unsympathetic, philandering, aggressive and disinterested in parenting. In fact, there is evidence that they really do have more relationship problems than other men. In a small study led by psychologist James Roney at the University of California, Santa Barbara, 29 women were asked to look at photos of men and rate their masculinity and fondness for infants. (The men had already been tested for child-friendliness and testosterone levels.) The men who were rated as the most masculine generally had higher testosterone levels; the women also were generally accurate in assessing child-friendliness.
