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.

Sexual competition among females: What causes courtship-role reversal?

Trends in Ecology & Evolution, 1991
In most animals, males are the competitive sex whereas females are typically non-competitive and choosy of mates. In a variety of taxa, certain species (or populations within species) show a reversal in these typical courtship roles. Recent research with these organisms supports a central tenet of sexual selection theory: that it is the relative ...

Evolution of Reversed Sexual Size Dimorphism: Sex or Starvation?

Ornis Scandinavica, 1989
Lundberg (1986) has proposed that reversed sexual dimorphism (RSD) in owls has evolved as a result of selection for larger mass in females to resist starvation and shorter wings in males for more efficient foraging. His hypothesis is based on (1) a lack of correlation between RSD in weight and RSD in wing in European owls, (2) a correlation between RSD
