Sexual behavior in male rodents.

Female and male sexual responses in female cats with ventromedial hypothalamic lesions.

The effects of lesions in the ventromedial hypothalamus (VMH) on male and female sexual behavior in female cats were examined. Following preoperative testing for receptivity, proceptivity, and male mating behavior, 27 female cats received either lesions in the anterior or posterior portion of the VMH or sham lesions. Neither of the VMH lesion placements reduced proceptivity and receptivity scor...

The Effects of Lead Acetate on Sexual Behavior and the Level of Testosterone in Adult Male Rats

The Effect of Chronic Ethanol Consumption on Sexual Motivation and Behavior of Adult Male Wistar Rats in the Copulatory Phase

Background: The interaction of ethanol consumption and sexual behavior has been evaluated over the past three decades; however, some studies have assessed how ethanol consumption affects the general behavioral aspects of the copulatory cycle patterns in male rats. The aim of this study was to investigate the effect of chronic ethanol consumption on adult male Wistar rats' sexual motivation and ...

Sexual experience affects reproductive behavior and preoptic androgen receptors in male mice.

Reproductive behavior in male rodents is made up of anticipatory and consummatory elements which are regulated in the brain by sensory systems, reward circuits and hormone signaling. Gonadal steroids play a key role in the regulation of male sexual behavior via steroid receptors in the hypothalamus and preoptic area. Typical patterns of male reproductive behavior have been characterized, howeve...

Dopamine, the medial preoptic area, and male sexual behavior.

The medial preoptic area (MPOA), at the rostral end of the hypothalamus, is important for the regulation of male sexual behavior. Results showing that male sexual behavior is impaired following MPOA lesions and enhanced with MPOA stimulation support this conclusion. The neurotransmitter dopamine (DA) facilitates male sexual behavior in all studied species, including rodents and humans. Here, we...

Organization of mating behavior in male hamsters (Mesocricetus auratus).

Factor analysis was applied to standard measures of sexual behavior in 73 male hamsters (Mesocricetus auratus) as they interacted with hormone-primed females. The results suggest that 5 factors, or conceptual mechanisms, function in the organization of the behaviors observed in the first 2 copulatory series. Of these, the 3 that relate to the behaviors in the first copulatory series were compar...
