OBJECTIVE Penile erection following epidural anesthesia is an infrequent occurrence of unclear etioogy. It is very troublesome to perform the procedure during penile erection and attempting it leads to various complications. Three such cases are reported herein. The literature on the pathophysiology and management of intraoperative penile erection is discussed. METHODS Eighteen hundred patien...

PURPOSE Penile erection is dependent on commands from the central nervous system. Although basic studies of animals and neuroimaging studies of humans have been conducted to identify key brain regions associated with sexual arousal, to our knowledge no reliable studies of the first excitation phase of sexual arousal leading to penile erection have been reported. MATERIALS AND METHODS We used ...

Penile erection is the ultimate vasculo-tissular response to an integrated and complex series of physiological processes elicited by psychological, neural, and hemodynamic events (Giuliano and Rampin, 2000; Saenz de Tejada, 2002). Upon sexual stimulation, penile erection, occurring in response to the activation of proerectile autonomic pathways, is greatly dependent on adequate inflow of blood ...

INTRODUCTION Understanding the physiology of penile erection is important for all who work in the field of sexual medicine. AIM The aim of this study was to highlight and analyze historical aspects of the scientific understanding of penile erection. METHODS (i) Review of the chapters on the physiology of erection out of the author's collection of books dealing with male sexual functioning p...

The erectile status of penile tissue is governed largely by the tone of cavernosal smooth muscle cells, which is determined by the balance of vascular relaxants and constrictors. Vascular relaxants play a key role in regulating the tone of cavernosal smooth muscle and thus the initiation and maintenance of penile erection. Early studies drew attention to the potential role of adenosine signalin...

OBJECTIVE To evaluate the change in penile size r bilateral nerve sparing retropubic radical prostatectomy (BNSRRP) and possible effect of Tadalafil. MATERIALS AND METHODS A total of 65 patients underwent BNSRRP and they were evaluated prospectively for a whole year of follow-up. The patients were randomized to control without rehabilitation (Group 1) or Tadalafil rehabilitation group (Group ...

The cholinergic neurons in the laterodorsal tegmental nucleus (LDT) play a crucial role in the regulation of rapid eye movement (REM) sleep. Because penile erection occurs during REM sleep, the involvement of the LDT in penile erection was examined in unanesthetized head-restrained rats. To detect penile erection, corpus spongiosum of the penis (CSP) pressure was measured through a telemetric d...

Priapism is defined as having prolonged (more than 6 h), and usually painful penile erection that occurs without a sexual desire or arousal. Only a very few priapism cases caused by ziprasidone are reported in the literature. In this case report we aimed to present a prolonged penile erection due to use of ziprasidone.

INTRODUCTION Outcome data of penile traction therapy (PTT) for the acute phase (AP) of Peyronie's disease (PD) have not been specifically studied. AIM The aim of this study was to assess the effectiveness of a penile extender device for the treatment of patients with AP of PD. METHODS A total of 55 patients underwent PTT for 6 months and were compared with 41 patients with AP of PD who did ...

OBJECTIVES Controversial data on penile length after radical retropubic prostatectomy are available. We hypothesised that postoperative penile size correlates to erectile function following bilateral nerve-sparing radical retropubic prostatectomy (BNSRRP). METHODS Thirty-three consecutive patients with a preoperative erectile function domain of the International Index of Erectile Function (II...
