Emotion dysregulation and risky Sexual Behavior in revictimization
Child Abuse and Neglect, 2010Co-Authors: Terri L. Messman-moore, Kate L. Walsh, David DililloAbstract:Objective: The current study examined emotion dysregulation as a mechanism underlying risky Sexual Behavior and Sexual revictimization among adult victims of child Sexual abuse (CSA) and child physical abuse (CPA). Methods: Participants were 752 college women. Victimization history, emotion dysregulation, and risky Sexual Behavior were assessed with anonymous, self-report surveys utilizing a cross-sectional design. Results: Approximately 6.3% of participants reported CSA, 25.5% reported CPA, and 17.8% reported rape during adolescence or adulthood. CSA and CPA were associated with increased risk for adolescent/adult rape; 29.8% of CSA victims and 24.3% of CPA victims were revictimized. Path analytic models tested hypothesized relationships among child abuse, emotion dysregulation, adolescent/adult rape and three forms of risky Sexual Behavior (e.g., failure to use condoms, contraception, or having sex with someone under the influence of alcohol/drugs), including frequency of risky Sexual Behavior with a regular dating partner, with a stranger, and lifetime number of intercourse partners. Emotion dysregulation mediated revictimization for both CSA and CPA. Emotion dysregulation also predicted lifetime number of Sexual partners and frequency of risky sex with a stranger, but not frequency of risky sex with a regular dating partner. Conclusions: Findings suggest that emotion dysregulation is a distal predictor, and risky sex, particularly with lesser known partners, is a proximal predictor of Sexual revictimization. Because emotion dysregulation also maintained a significant direct path to revictimization, risky Sexual Behavior appears to be one of several proximal risk factors for revictimization. Practice implications: Findings confirm that emotion dysregulation is a critical pathway to more proximal risk factors such as risky Sexual Behavior, and suggest that clinical interventions aimed at improving emotion dysregulation may help reduce risky Sexual Behavior and risk for revictimization. © 2010 Elsevier Ltd.

Sexual Behavior and Intention to Engage in Sexual Behavior Among Young Adolescents in Hong Kong: Findings Based on Four Waves of Data
Quality of Life in Asia, 2020Co-Authors: Daniel T. L. Shek, Hildie LeungAbstract:This study examined the growth trajectories of Sexual Behavior and intention to engage in Sexual Behavior among young adolescents in Hong Kong across 4 years. Besides, the impact of family structure and economic disadvantage on the rate of change in adolescent Sexual Behavior and intention was studied, and the concurrent and longitudinal impact of family functioning and positive youth development on adolescent Sexual Behavior and intention was explored. Four waves of data were collected from adolescents (n = 3328 at Wave 1) in 28 secondary schools in Hong Kong. Individual growth curve models generally showed that adolescents from economically disadvantaged and non-intact families increased their Sexual Behavior at a faster rate than their counterparts, but they did not affect the rate of acceleration in intention to engage in Sexual Behavior. Multiple regression analyses revealed that family functioning and positive youth development influenced adolescent Sexual Behavior and intention.

Sexual Behavior and intention to engage in Sexual Behavior in junior secondary school students in Hong Kong.
Journal of pediatric and adolescent gynecology, 2020Co-Authors: Daniel T. L. ShekAbstract:The present study examined the prevalence, changes, and demographic as well as psychosocial correlates of Sexual Behavior and intention to engage in Sexual Behavior in early adolescents in Hong Kong, with Sexual Behavior indexed by Sexual intercourse. Three waves of longitudinal data on Sexual intercourse, intention to engage in Sexual intercourse, family functioning, and positive youth development were collected from 28 secondary schools in Hong Kong. There were significant influences of grade and gender on adolescent Sexual Behavior or intention to engage in Sexual Behavior. Significant main effects of immigration status on Sexual Behavior were also found. While no effect of family economic background was found, effect of family intactness existed for Sexual Behavior. Family functioning and positive youth development at Grade 7 were negatively associated with students' Sexual Behavior and intention to engage in Sexual Behavior at Grade 9. Grade, gender, immigration status, and family intactness were related to Sexual Behavior and/or intention to engage in Sexual Behavior in junior secondary school students. Promoting positive youth development and family functioning could serve as protective factors to reduce Sexual Behavior and intention to engage in Sexual Behavior in Chinese early adolescents in Hong Kong.

amyloid β precursor protein regulates male Sexual Behavior
The Journal of Neuroscience, 2010Co-Authors: Jin Ho Park, Paul J Bonthius, Houng Wei Tsai, Stefan Bekiranov, Emilie F. RissmanAbstract:Sexual Behavior is variable between individuals, ranging from celibacy to Sexual addictions. Within normal populations of individual men, ranging from young to middle aged, testosterone levels do not correlate with libido. To study the genetic mechanisms that contribute to individual differences in male Sexual Behavior, we used hybrid B6D2F1 male mice, which are a cross between two common inbred strains (C57BL/6J and DBA/2J). Unlike most laboratory rodent species in which male Sexual Behavior is highly dependent upon gonadal steroids, Sexual Behavior in a large proportion of these hybrid male mice after castration is independent of gonadal steroid hormones and their receptors; thus, we have the ability to discover novel genes involved in this Behavior. Gene expression arrays, validation of gene candidates, and transgenic mice that overexpress one of the genes of interest were used to reveal genes involved in maintenance of male Sexual Behavior. Several genes related to neuroprotection and neurodegeneration were differentially expressed in the hypothalamus of males that continued to mate after castration. Male mice overexpressing the human form of one of these candidate genes, amyloid β precursor protein (APP), displayed enhanced Sexual Behavior before castration and maintained Sexual activity for a longer duration after castration compared with controls. Our results reveal a novel and unexpected relationship between APP and male Sexual Behavior. We speculate that declining APP during normal aging in males may contribute to the loss of Sexual function.

Dopamine D5 receptor modulates male and female Sexual Behavior in mice
Psychopharmacology, 2005Co-Authors: A. E. Kudwa, E. Dominguez-salazar, D. M. Cabrera, D. R. Sibley, Emilie F. RissmanAbstract:Rationale Dopamine exerts its actions through at least five receptor (DAR) isoforms. In female rats, D5 DAR may be involved in expression of Sexual Behavior. We used a D5 knockout (D5KO) mouse to assess the role of D5 DAR in mouse Sexual Behavior. Both sexes of D5KO mice are fertile and exhibit only minor disruptions in exploratory locomotion, startle, and prepulse inhibition responses. Objective This study was conducted to characterize the Sexual Behavior of male and female D5KO mice relative to their WT littermates. Methods Female WT and D5KO littermates were ovariectomized and given a series of Sexual Behavior tests after treatment with estradiol benzoate (EB) and progesterone (P). Once Sexual performance was optimal the dopamine agonist, apomorphine (APO), was substituted for P. Male mice were observed in pair- and trio- Sexual Behavior tests. To assess whether the D5 DAR is involved in rewarding aspects of Sexual Behavior, WT and D5KO male mice were tested for conditioned place preference. Results Both WT and D5KO females can display receptivity after treatment with EB and P, but APO was only able to facilitate receptivity in EB-primed WT, not in D5KO, mice. Male D5KO mice display normal masculine Sexual Behavior in mating tests. In conditioned preference tests, WT males formed a conditioned preference for context associated with either intromissions alone or ejaculation as the unconditioned stimulus. In contrast, D5KO males only showed a place preference when ejaculation was paired with the context. Conclusions In females, the D5 DAR is essential for the actions of dopamine on receptivity. In males, D5 DAR influences rewarding aspects of intromissions. Taken together, the work suggests that the D5 receptor mediates dopamine’s action on Sexual Behavior in both sexes, perhaps via a reward pathway.

Neural aromatization and the control of Sexual Behavior.
Trends in Endocrinology and Metabolism, 1996Co-Authors: Louise M. Freeman, Emilie F. RissmanAbstract:Abstract Neural aromatization of androgens to estrogens is known to be a critical step in the development and adult expression of male Sexual Behavior in a variety of species. The medial preoptic area (mPOA) is an important site of aromatization necessary for the expression of copulatory Behavior in males. The neuroendocrine regulation of female Sexual Behavior in the musk shrew, an evolutionary "primitive" insectivore, shares several similarities with the regulation of male Sexual Behavior in many other species. We review the evidence that neural aromatization in the mPOA triggers female Sexual Behavior in the musk shrew, and speculate on the presence of a similar pathway in other mammalian species.
