Y1 - 2011 N1 - T2 - Rudolph's Pediatrics, 22e AB - Specific behavioral changes are associated with puberty and its timing.1-3 Androgens have been implicated as the cause of many of the changes associated with adolescence.4,5 Family relationships undergo a transformation during puberty.6,7 During peak height velocity (Tanner and Marshall sexual maturity rating [SMR] 3–4), boys experience more conflict with their parents, especially their mothers. This conflict tends to subside after completion of puberty, with mothers deferring more to their sons. Girls experience conflict with their mothers, and girls report decreased contact with their fathers. Hormones have been implicated as the cause of many of the behavior changes associated with normal and abnormal adolescence. Sexual behavior is associated with changes in androgens.8 Boys, with rising levels of testosterone, initiate coitus, and they are reported to be more impatient, aggressive, and irritable. For girls, an increase in masturbatory activity is associated with rising levels of androgens.
