Conditioned suppression of sexual behavior in stallions and reversal with diazepam
Physiology & Behavior, 1985Sexual behavior dysfunction unaccompanied by detectable physical or endocrine abnormality is an important cause of reproductive failure among domestic stallions. Several authors have suggested that such dysfunction may be psychogenic, related to negative experience associated with intense handling and training.

Reversal of hippocampal sexual dimorphism by gonadal steroid manipulation
Brain Research, 1984Hippocampal 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.

Reversed sexual dimorphism in the leg muscle architecture of the Eurasian sparrowhawk
The Anatomical Record, 2022AbstractReversed sexual dimorphism (RSD) in size is a deep issue in evolutionary biology. RSD in body mass and linear measures is pronounced in diurnal predatory bird species, especially in those that feed on other birds. Size differences between males and females in internal organs or systems, such as the appendicular musculature, are less well known.

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 ...

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.

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.

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 ...

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 ...

Zinc Deficiency and Hyperprolactinaemia are not Reversible Causes of Sexual Dysfunction in Uraemia
Nephrology Dialysis Transplantation, 1989We selected a group of male dialysis patients complaining of sexual dysfunction in whom penile vascular insufficiency and drug-induced impotence had been excluded. Monitoring of nocturnal penile tumescence was used to confirm organic disturbance. Patients with normal serum prolactin concentrations (n = 18) had significantly lower serum zinc values than
