BACKGROUND: Radical prostatectomy is often followed by long-lasting erectile dysfunction and urinary incontinence, with adverse effects on the quality of life and intimate relationship of patients and partners. We developed the ProCan intervention to ameliorate sexual and urological dysfunction after radical prostatectomy and examined its feasibility, acceptability and changes in sexual function. MATERIAL AND METHODS: Between May 2014 and October 2014, seven couples attending the Department of Urology, Rigshospitalet, were included 3-4 weeks after radical prostatectomy in the ProCan intervention, which consists of up to six couple counselling sessions, group instruction in pelvic floor muscle training (PFMT), up to three individual PFMT sessions and a DVD home training program...

We report here a case of strangulation of the penis. A 69-year-old male visited our hospital suffering from a swollen penis and dysuria after installation of four metallic washers to the penis. He had mischievously put them on his penis four days before and subsequently was unable to remove them. We found erosion on the surface of the penis, reduction in blood flow by ultrasonography, and high C-reactive protein levels. Because we could not remove washers by blood removal from glans penis or ring cutter, we performed percutaneous cystostomy and then cut the washers with an electric grinder under general anesthesia...

: Radical prostatectomy (RP) for prostate cancer treatment, although effective, can lead to severe erectile dysfunction. This study describes a new technique, which aims to reestablish the nerve stimulus in penile erection by two sural nerve graft bridges bilaterally, using the end to side neurorraphy. The first bridge is between femoral nerve and dorsal nerve of penis and the second, is between the femoral nerve and the interior of the corpus cavernosum. In this neurorraphy the endings of the newly formed fibres, generated by the femoral nerve, release acetylcholine inside the cavernous bodies, beginning the erection mechanism...

INTRODUCTION: Obesity is an independent risk factor for erectile dysfunction (ED) and lower urinary tract symptoms (LUTS). Bariatric surgery has been shown to improve erectile function and urinary symptoms in medium- to long-term studies (3- to 12-month postoperative follow-up). AIM: To investigate the early effect (1 month postoperatively) of bariatric surgery on ED and LUTS, which has not previously been investigated. METHODS: Morbidly obese men (body mass index > 35 kg/m(2)) undergoing bariatric surgery were asked to complete the International Index of Erectile Function (IIEF) and International Prostate Symptom Score (IPSS) questionnaires before surgery and 1, 3, and 6 months after surgery...

BACKGROUND: Drug use among gay and bisexual men (GBM) is higher than most populations. The use of crystal methamphetamine, erectile dysfunction medication (EDM), and amyl nitrite have been associated with sexual risk behaviour and HIV infection among gay and bisexual men (GBM). OBJECTIVE: This paper describes an online prospective observational study of licit and illicit drug use among GBM and explores baseline prevalence of drug use in this sample. Capturing these data poses challenges as participants are required to disclose potentially illegal behaviours in a geographically dispersed country...

Lipoprotein (a) [Lp(a)] is an independent but moderate, predictor for coronary heart disease (CHD) prevalence and severity. Several established and emerging cardiovascular (CV) risk factors including age, gender, ethnicity, smoking, dyslipidemia, hypertension, obesity, type 2 diabetes mellitus, alcohol consumption, arterial stiffness and hyperuricemia have been linked to Lp(a) metabolism. Apart from CHD, Lp(a) has been also associated with non-cardiac vascular diseases and diseases associated with increased CV risk such as chronic kidney disease, metabolic syndrome, non-alcoholic fatty liver disease, erectile dysfunction, obstructive sleep apnea syndrome, inflammatory bowel diseases and human immunodeficiency virus infection...

The goal of testosterone replacement therapy (TRT) is to return serum testosterone levels to within physiologic range and improve symptoms in hypogonadal men. Some of the symptoms aimed to improve upon include decreased libido, erectile dysfunction, infertility, hot flashes, depressed mood, and loss of muscle mass or hair. Clinical use of testosterone for replacement therapy began approximately 70 years ago. Over the decades, numerous preparations and formulations have been developed primarily focusing on different routes of delivery and thus pharmacokinetics (PKs)...

BACKGROUND: Hypogonadism is common in patients with renal dysfunction and does not always correct following transplantation. Recent studies show increased mortality for dialysis and transplant patients with low testosterone (T). These patients are often not treated due to concerns over efficacy and complications (both real and imagined). There is surprisingly scant literature supporting the use of T therapy in these patients. We wished to examine the results of T therapy in our patients with renal failure or following transplant...

Erectile dysfunction (ED) associated with type 2 diabetes mellitus (T2DM) involves dysfunctional nitric oxide (NO) signaling and increased oxidative stress in the penis. However, the mechanisms of endothelial NO synthase (eNOS) and neuronal NO synthase (nNOS) dysregulation, and the sources of oxidative stress, are not well defined, particularly at the human level. The objective of this study was to define whether uncoupled eNOS and nNOS, and NADPH oxidase upregulation, contribute to the pathogenesis of ED in T2DM men...

We present a case report of an atypical giant pituitary adenoma secreting follicle-stimulating hormone (FSH). A 55-year-old patient presented for erectile dysfunction, loss of libido and fatigue. The biochemical evaluation showed very high FSH serum levels in the presence of central hypogonadism. Neither testicular enlargement nor increased sperm count was observed, thus a secretion of FSH with reduced biological activity was supposed. The histological examination after neuro-surgery showed an atypical pituitary adenoma with FSH-positive cells...

INTRODUCTION: Erectile dysfunction (ED) worsens in men with diabetes. Human umbilical cord blood (HUCB), because of its widespread availability and low immunogenicity, is a valuable source for stem cell-based therapies. AIM: To determine the effect of intracavernous injection of HUCB mononuclear cells (MNCs) on ED in rats with diabetes induced by streptozotocin. METHODS: Thirty adult male Sprague-Dawley rats were equally divided into three groups: (i) control, (ii) diabetes induced by streptozotocin (35 mg/kg intravenously for 8 weeks), and (iii) diabetic rats treated with MNCs (1 × 10(6) cells by intracavernosal injection)...
