Mechanisms of Erection

The septum modulates REM sleep-related penile erections in rats

Rapid eye movement sleep in males is characterized by penile erection along with EEG desynchronization, muscle atonia, ponto-geniculo-occipital waves, and rapid eye movements (REM). The central neural mechanisms regulating sleep related erections (SREs) are not known. Recently, the lateral preoptic area has been shown to contribute in sleep-related erectile mechanisms. The present study was con...

Role of nitric oxide in the physiology of erection.

Penile erection is understood to be a neurally regulated physiologic event, although the underlying mechanisms have eluded characterization for more than a century. The classical autonomic parasympathetic and sympathetic nervous systems are involved, but the process of erection does not appear to require cholinergic or adrenergic mechanisms. As the search for the principal mediator of penile er...

O-6: Pharmacological and Molecular Evaluation of Herbal Drugs in The Treatment of Sexual Dysfunction and As Stimulating Agents

Background: Vajikarana herbs from Ayurveda are known to enhance the sexual performance in folklore. The objective is to evaluate their effect by molecular and pharmacological screening. Materials and Methods: In the present study, the effect of four Vajikaran Rasayana herbs on penile erection, sperm count, seminal fructose content in vivo and nitric oxide (NO) release in vitro was assessed. Pen...

درمان بیماری پیرونی با استفاده از امواج شوک خارج بدنی (ESWT)

Background and purpose : Since the first report of the pyronier’s disease in 1374, different thrapeutic and surgical methods have been used for treatment. However, none resulted in complete satisfactory outcome. The aim of this study was to treat the disease using exteral shook wave thrapy (ËSWT). Materials and methods: Tweixe patients were included in the study after singning the writhen ...
