Previous behavioral studies have indicated that the nucleus accumbens (NAc) shell of a male rat is involved in its sexual behavior; however, no previous studies have investigated neuronal activities in the male rat NAc shell during sexual behavior. To investigate this issue, we recorded single unit activities in the NAc shell of male rats during sexual behavior. Of 123 NAc shell neurons studied...

The current study examines teenage sexual behavior ( in terms of having had sexual intercourse) as a function of sexual attitudes and sexual efticacy. At the heart ofthe study lies the assumption that sexual attitudes such as permissiveness are related to sexual behavior, but that this relation is stronger for sexually eficacious teenagers than for others. Using longitudinal data from 253 Briti...

Since adolescents are now engaging in sexual activity in their early years, sexual behavior needs to be explored to prevent contact with HPVs and other sexually transmitted diseases (STD), including cervical cancer. This qualitative study aimed to explore this question from adolescents' view points in their natural context. The participants were 19 individuals aged 13-19 years living in rural f...

Children exhibiting sexual behavior have increasingly gained the attention of child welfare and mental health systems, as well as the scientific community. While a heterogeneous group, children with sexual behavior problems consistently demonstrate a number of problems related to adjustment and overall development. In order to appropriately intervene with these children, a comprehensive underst...

3,4-Methylenedioxymethamphetamine (MDMA, "Ecstasy") is a potent neurotoxin which preferentially produces 5-HT nerve terminal degeneration in the CNS in both rodents and primates. Timely research on the behavioral effects of acute and long term treatment of MDMA is critical due to the neuropathological effects of MDMA and its abuse liability. Presently, there are no published reports that have s...

Sexual behaviors in children are common, occurring in 42 to 73 percent of children by the time they reach 13 years of age. Developmentally appropriate behavior that is common and frequently observed in children includes trying to view another person's genitals or breasts, standing too close to other persons, and touching their own genitals. Sexual behaviors become less common, less frequent, or...

Perinatal action of estrogens or aromatizable steroids at the central nervous system level is responsible for brain sexual differentiation. Through early contact with the central nervous system, the estrogenic compound bisphenol A (BPA) could alter the processes affecting sociosexual behavior. To test this hypothesis, we studied agonistic and sexual behavior of adult female and male rats whose ...

Much research has been conducted on ethnic differences in sexuality, but few studies have systematically assessed the importance of acculturation in sexual behavior. The present study assessed general differences in normative sexual practices in healthy Euro-American, Asian, and Hispanic populations, using measures of acculturation to analyze the relative effects of heritage and mainstream cult...

Gonadal hormones regulate the ability to copulate in most mammalian species, but not in primates because copulatory ability has been emancipated from hormonal control. Instead, gonadal hormones primarily influence sexual motivation. This separation of mating ability from hormonally modulated mating interest allows social experience and context to powerfully influence the expression of sexual be...
