We aimed to assess the effects of family planning services on abortion rates in two similar areas. METHODS We examined trends in overall abortion rates and rates for intended and(More)

A small percentage of mice so isolated fail to become aggressive and in fact, behaviorally are strikingly different in that they develop a 'timid' behavior. Isolation-induced aggression is an androgen-dependent behavior and androgen-sensitive neurons have been(More)
