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, 1982The 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.

Gamete Research, 1979
AbstractWashing in fresh culture medium or short exposure to ultraviolet irradiation (UV) was found to reverse the action of the sexual pheromone produced by the green alga Volvox carteri. Induced gonidia which would normally form egg‐bearing females formed mainly asexual individuals in response to these treatments.

Sexual behavior induces naloxone-reversible hypoalgesia in male rats
Neuroscience Letters, 1987The 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 ...

European Journal of Pharmacology, 1999
The possible interaction of yohimbine with the dopaminergic system in the mediation of sexual behaviour expression in sexually exhausted male rats was investigated. The behavioural effects of the simultaneous injection of yohimbine (500 microg/kg) plus apomorphine (50 microg/kg) and those of the combined treatment of haloperidol (125 microg), a ...

Escapes into Fiction: Violent Sexual Fantasy, Magical Reversal and Human Sexuality
2013It 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.

Reversal of normal cerebral sexual dimorphism in schizophrenia: Evidence and speculations
Medical Hypotheses, 2007Sex differences in epidemiology, clinical course and symptomatology of schizophrenia have been widely documented, but still relatively little is known about the brain sexual dimorphism in this psychiatric disorder. While some neuroanatomical and neuropsychological studies have reported existence of differences between male and female patients in a ...
