Veterinary Clinics of North America: Equine Practice, 1986
Behavior during the estrous phase of the ovulatory cycle of the mare is analogous in most ways to that of estrous females of other species. Proceptive behaviors bring the mare into the proximity of the male and attract his attention. Positioning facilitates mounting, intromission, and ejaculation. Estrous signs appear to be more intense in the few days

On the origin of sexual behavior
Psychoneuroendocrinology, 1982Abstract All-female parthenogenetic species afford a unique opportunity to probe the nature and origin of sexual behavior. Whereas the majority of vertebrates are gonochoristic (that is, they rely for reproduction on fertilization of female ova by male sperm), at least 27 species of squamate reptiles representing seven families consist mostly or ...

Neuroscience & Biobehavioral Reviews, 1995
Among central neurotransmitters involved in the control of sexual behavior, dopamine is certainly one of the most extensively studied. Our attempt to review old and recent neuropharmacological, biochemical, electrophysiological, and psychobiological studies performed so far only in rats, monkeys, and humans, provides evidence that dopamine through its ...

Minerva ginecologica, 2000Adolescence represents the period with the highest frequency of negative consequences associated with sexual activities (sexually transmitted diseases and unwanted pregnancies). An epidemiological study was carried out in symptomatic patients attending our Outpatient Clinic for Sexually Transmitted Diseases between April 1995 and April 1999 in order to

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.

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 ...
