Neuroscience & Biobehavioral Reviews, 1987
Opioids have long been known to inhibit sexual behavior. However, it is only within the last decade that the effects of opioids on sexual behavior have been studied extensively and a number of hormonal and neurochemical correlates established. In this review, the experimental literature on opioids and sexual behavior in humans and laboratory animals is

Sexualized behaviors on Facebook
Computers in Human Behavior, 2016Currently, social networks are places where young people socialize and develop their digital identities. One of the most common risky behaviors among young people is sexualized behavior, which is promoted in social networks due to an interface that makes content exchange easier, for example, by sharing pictures, messages, videos, etc.

Annual Review of Neuroscience, 1988
Sex differences in behavior are the result of natural and sexual selection. The dimorphic classes of behavior described here, courtship, copulatory, and parental behaviors, reflect both kinds of evolutionary selective pressures. We can further distinguish two kinds of mechanisms that produce differences in male and female behaviors. In one, both sexes

Psychiatric Clinics of North America, 1995
CSBs constitute a wide range of complex sexual behaviors that clinicians are increasingly encountering. This article has set forth four models of CSBs: compulsive, affective, addictive, and impulsive. Some of the CSBs appear to fit rather neatly into one of the models, whereas others have features of two or more of them.

Male sexual behavior comprises a complex pattern of genital and somatomotor responses. Hormones act via receptors in brain, spinal, and peripheral sites to bias sensory inputs and motor outputs to favor sexual responsiveness. Copulation includes mounts, intromissions, and ejaculations, followed by sexual quiescence.

The mating behavior of Drosophila melanogaster is a stereotyped sequence of fixed action patterns, composed of orientation, tapping, singing, licking, attempted copulation and copulation. Mutations that block a unique aspect of mating behavior were isolated and analyzed at the cellular and molecular levels.

Hormones and Behavior, 2007
The mare is seasonally polyestrus, having an anovulatory period during the short light days of late fall and early winter, and beginning to ovulate as the days become longer during the winter. The complete estrus cycle is typically about 3 weeks, with 5 to 7 days of estrus and approximately 2 weeks of diestrus.

Neurobiology of sexual behavior
Current Opinion in Neurobiology, 1999Recent advances in the neurobiology of sexual behavior have helped to refine our understanding of the neuroanatomical, neuroendocrine and neurochemical systems that modulate responses to sexual stimulation. Both appetitive and consummatory sexual behaviors have been studied in several laboratory species and in humans using traditional and novel ...

Sexual Behavior of Adolescents
Postgraduate Medicine, 1969Unwanted pregnancy is a disease with consequences that affect every level of society. Illegitimacy is rising to the point where it is a major social problem. Findings of the National Center for Health Statistics show that in the 1940-1965 period illegitimacy tripled. More than 40% of unwed mothers are teenagers.

American Journal of Psychotherapy, 1994
Case material is presented from two patients suffering from addictive sexual behavior. The term addiction is used because of the intense, driven quality of the behavior and because of its mood-elevating effects. Psychodynamically, the patients’ sexual acts helped to undo feelings of rejection at the hands of their mothers and to ...
