Reversal of hippocampal sexual dimorphism by gonadal steroid manipulation

Brain Research, 1984
Hippocampal slices display a sexually dimorphic pattern of physiological neuromodulation to gonadal steroid administration. To determine if this is the result of organizational or activational hormone action, plasma steroid levels of adult male rats were manipulated.

Reversal of sexual exhaustion by serotonergic and noradrenergic agents

Behavioural Brain Research, 1994
The possible participation of the serotonergic and the noradrenergic systems in the control of the inhibitory state present during sexual satiation was studied from a pharmacological perspective. It was found that the 5-HT1A agonist 8-OH-DPAT and the alpha 2 adrenoceptor antagonist, yohimbine were effective in reversing the sexual inhibition resulting ...

Sexual behavior induces naloxone-reversible hypoalgesia in male rats

Neuroscience Letters, 1987
The sensitivity to painful and sexual stimuli in male rats was markedly suppressed immediately after ejaculation and enhanced after the postejaculatory refractory period. The suppression of pain sensitivity induced by sexual activity was reversed, but sexual behavior was only slightly affected by intraperitoneal (i.p.) injection of the opioid ...

Escapes into Fiction: Violent Sexual Fantasy, Magical Reversal and Human Sexuality

2013
It is difficult to access violent sexual fantasies on the level of the individuals who elaborate them because, given that they are private and work to remedy trauma connected to the individual’s sense of sexual potency, such personalities are unlikely to see much advantage for themselves in revealing them.

Reversible suppression of sexual activity in tomcats with deslorelin implant

Theriogenology, 2012
The aim of the study was to assess the efficacy of using a Gn-RH agonist implant (deslorelin, 4.7 mg, Suprelorin) to control sexual activity of male cats and reestablishment of sexual function after the implant removal 4 mo after placement. Using a control group (Group 1, n = 5), 22 domestic tomcats were given the implant subcutaneously in the region ...

Stimulation of the medial preoptic area facilitates sexual behavior but does not reverse sexual satiation.

Behavioral Neuroscience, 2000
The aim of the present study was to establish whether electrical and/or drug stimulation of the medial preoptic area/anterior hypothalamus (mPOA/AH) surmounts the sexual behavior inhibition that results from copulation to exhaustion. Thus, intermittent electrical stimulation of the mPOA/AH (alone or combined with the systemic injection of yohimbine or ...

Reversal by bethanechol of sexual dysfunction caused by anticholinergic antidepressants

American Journal of Psychiatry, 1982
The anticholinergic properties of currently available antidepressants sometimes cause sexual dysfunction. Bethanechol, a cholinergic drug, was found to give total relief of impotence in two men and of anorgasmy in one woman; none of the subjects suffered side effects.

Sexual maldevelopment and sex reversal, chromosomal causes.

Journal of the Association of Genetic Technologists, 2007
The SRY gene on the Y chromosome is the testis determining factor (TDF). It is therefore the initial male determining factor. However, phenotypic sex determination includes a cascade of genes located on autosomes as well as sex chromosomes. Aberrations of these genes may cause sexual maldevelopment or sex reversal. Abnormalities may include single gene

Ovotestes and sexual reversal in racing pigeons.

The Canadian veterinary journal = La revue veterinaire canadienne, 2010
The occurrence of ovotestes associated with male behavioral characteristics in two mature female racing pigeons (Columba livia) is recorded. An ovotestis developed in the area of the vestigial right gonad of one bird and within the functional left ovary of the second bird.
