Estrogen receptor (ER)-α mediates estradiol (E2) actions in the male gonads and brain and is critical for normal male reproductive function. In the classical pathway, ERα binds to estrogen response elements (EREs) to regulate gene transcription. ERα can also regulate gene transcription independently of EREs via protein-protein interactions with transcription factors and additionally signal via rapid, nongenomic pathways originating at the cell membrane. This study assessed the degree to which ERE-independent ERα signaling can rescue the disrupted masculine sexual behaviors and elevated serum testosterone (T) levels that have been shown to result from ERα gene deletion. We utilized male ERα null mice that possess a ER knock-in mutation (E207A/G208A; AA), in which the mutant ERα is incapable of binding to DNA and can signal only through ERE-independent pathways (ERα−/AA mice). We found that sexual behavior, including mounting, is virtually absent in ERα−/− and ERα−/AA males, suggesting that ERE-independent signaling is insufficient to maintain any degree of normal sexual behavior in the absence of ERE binding. By contrast, ERE-independent signaling in the ERα−/AA mouse is sufficient to restore serum T levels to values observed in wild-type males. These data indicate that binding of ERs to EREs mediates most if not all of E2’s effects on male sexual behavior, whereas ERE-independent ERα signaling may mediate E2’s inhibitory effects on T production.

Summary: Hare's Psychopathy Checklist - Revised (PCL-R; Hare, 1991 ) was originally constructed for use among males in correctional and forensic settings. In this study, the PCL-R protocols of 36 matched pairs of female and male violent offenders were examined with respect to gender differences. The results indicated a few significant differences. By means of discriminant analysis, male Ss were distinguished from their female counterparts through their relatively higher scores on “callous/lack of empathy” (item 8) and “juvenile delinquency” (item 18), whereas the female Ss scored relatively higher on “promiscuous sexual behavior” (item 11). Some sources of bias and possible implications are discussed.

This review examines associations between parenting styles and the psychosexual development of adolescents. Methods and results of empirical studies of associations between parental support, control, and knowledge and the sexual behavior and sexual health of adolescents are described and evaluated. The results show that, in general, higher scores on support, control, and knowledge relate to a delay of first sexual intercourse, safer sexual practices, and higher sexual competence. Despite the vast amount of literature on this subject, the majority of these studies focus on single dimensions of parenting and unidirectional parenting influences. This review generates hypotheses regarding interactions of different parenting styles and reciprocal associations between parents and their children. There is a need for more dynamic, dialectical studies of parenting, and children’s sexual development.
