Erectile dysfunction is a common disease characterized by endothelial dysfunction. The aetiology of ED is often multifactorial but evidence is being accumulated in favor of the proper function of the vascular endothelium that is essential to achieving and maintaining penile erection. Uric acid itself causes endothelial dysfunction via decreased nitric oxide production. This study aims to evaluate the serum uric acid (SUA) levels in 180 ED patients, diagnosed with the International Index of Erectile Function-5 (IIEF-5) and 30 non-ED control...

INTRODUCTION: Penile size has long been an important fixation in men's lives. On the one hand, a smaller penis has been associated with anxiety and apprehension; on the other hand, a larger penis has generally been related to virility and strength. These perceptions predominate during an erection, when penile size is representative of a man's masculinity. AIM: To assess adult penile length and summarize average penile length assessments from the literature; analyze how various urologic diseases and therapies affect penile length and volume; and review how surgical treatments for Peyronie's disease, penile prosthesis implantation, and radical prostatectomy can affect penile size to appropriately counsel patients seeking such therapies and set realistic goals for patients...

PURPOSE/OBJECTIVES: Radiation-induced erectile-dysfunction (RiED) is one of the most common side effects of radiation therapy (RT) and significantly reduces the quality of life (QoL) of cancer patients. Approximately 50% of prostate cancer patients experience RiED within 3 to 5 years after completion of RT. A series of vascular, muscular, and neurogenic injuries after prostate RT lead to RiED; however, the precise role of RT-induced neurogenic injury in RiED has not been fully established...

Penile erection is a neurovascular event and neurologic or vascular disturbances are major causes of erectile dysfunction (ED). Radical prostatectomy for prostate cancer not only induces cavernous nerve injury (CNI) but also results in cavernous angiopathy, which is responsible for poor responsiveness to oral phosphodiesterase-5 inhibitors. Dickkopf2 (DKK2) is known as a Wnt signaling antagonist and is reported to promote mature and stable blood vessel formation. Here, we demonstrated in CNI mice that overexpression of DKK2 by administering DKK2 protein or by using DKK2-Tg mice successfully restored erectile function: this recovery was accompanied by enhanced neural regeneration through the secretion of neurotrophic factors, and restoration of cavernous endothelial cell and pericyte content...

REVIEW
Richard Wassersug, Erik Wibowo
Erectile dysfunction (ED), the most commonly reported sexual problem for men, reduces the quality of life for both patients and their partners. Even when physiologically effective, long-term adherence to ED treatments is poor. We review here the implication of having patients' partners involved in ED treatment, starting with treatment selection. We suggest that having partners engaged from the outset may promote an erotic association of the treatment with the partner, i.e., conceptually linking the aid to the sexual pleasure that the partner provides...

BACKGROUND: Vasculogenic erectile dysfunction (VED) is considered as a common complication among people with type 2 diabetes (T2D). We tested whether changes in fatty acid (FAs) classes measured in erythrocytes are associated with increased risk of diabetic VED along with related risk factors. METHODS: We assessed erythrocyte FAs composition, lipid peroxidation parameters and inflammatory cytokines among 72 T2D men with VED, 78 T2D men without VED and 88 healthy volunteers with similar age...

Peyronie's disease (PD) is an acquired connective tissue disorder of the tunica albuginea with fibrosis and inflammation that lead to palpable plaques formation, penile curvature, and pain during erection. Patients report negative effects on main domains such as physical appearance and self-image, sexual function, and performance. The aim of this study was to evaluate plication of the albuginea outcomes after a long-term follow-up period. Between 1998 and 2006, a total of 204 patients with PD underwent surgical correction with albuginea plication technique...

BACKGROUND: Allium tuberosum is a well-known spice as well as a herb in traditional Chinese medicine, used for increasing libido and treating erectile dysfunction. However, not many studies have been done to evaluate the sexual enhancing properties of A. tuberosum. The aim of this study was to evaluate the aphrodisiac and vasorelaxant properties of A. tuberosum on corpus cavernosum smooth muscle (CCSM) as well as checking the effect on enhancing male rat sexual behavior, libido, potency as well as its spermatogenic properties...

BACKGROUND AND OBJECTIVE: With the increase in sphincter preserving rate of rectal cancer (RC) cancer, postoperative quality-of-life, such as genital dysfunction, has become a major issue in the patient management. In this study, we proposed a measurement, namely, the sphincter preserving length (SPL), and investigated the relationship between SPL and postoperative genital function and survival in RC patients. METHODS: A total of 536 male patients who had a diagnosis of RC and underwent sphincter preserving rectal resection in the Sixth Affiliated Hospital of Sun Yat-sen University and the First Affiliated Hospital of Sun Yat-sen University between October 1997 and December 2013 were included in our study...

Accurate data regarding the size of the erect penis is of great importance to several disciplines working with male patients, but little data exists on the best technique to measure penile length. While some previous small studies have suggested good correlation between stretched penile length, others have shown significant variability. Penile girth has been less well studied, and little data exist on the possible errors induced by differing observers and different techniques. Much of the published data report penile length measured from the penopubic skin junction-to-glans tip (STT) rather than pubic bone-to-tip (BTT)...

Erectile dysfunction (ED) is the most common sexual disorder that men report to healthcare providers. Gap junctions (GJs) are thought to be responsible for synchronous shrinkage of corpus cavernosum smooth muscle cells (CCSMCs), and play thus an important role in the maintenance of an erection. Hypoxia has been suggested as a pathological mechanism underlying ED. Here we demonstrate that hypoxia increased the expression of platelet-derived growth factor (PDGF) and the main GJ component connexin (Cx)43 in CCSMCs...

The article describes a case of successful managenent of arterial priapism in a patient with a stab wound in the perianal area. Timely performed angiography revealed a pathological connection between a. Uretralis sinistra and spongy body. Disruption of the abnormal shunt resulted in immediate relief of erection with further preservation of erectile function. At the 3 and 6 months follow-up visits there were no signs of cavernous fibrosis or erectile dysfunction. The authors analyze the entire sequence of events in the management of the case, identify shortcomings, determine their significance and consider their prevention...

Late onset hypogonadism (LOH) is the most commonly used term to indicate the age-dependent reduction of testosterone. Sexual dysfunction represents the most important determinant for medical consultation and the most specific symptoms associated with LOH. In particular, data from the European Male Ageing Study (EMAS), a population-based survey on more than 3400 subjects, recognized that a triad of sexual symptoms (low libido and reduced spontaneous and sex-related erections) is the only syndromic association with decreased testosterone levels...
