Guideline of guidelines – testosterone therapy for testosterone deficiency

The authors conducted an internet search and analysed guidelines for testosterone therapy (TTh) produced by the American Urological Association (AUA), European Association of Urology (EAU), American Association of Clinical Endocrinologists (AACE), British Society of Sexual Medicine (BSSM), Endocrine Society (ES),...

Preoperative testosterone for hypospadias

Hypospadias affects around 1 in 400 boys. Glans width (GW) of <14mm has been shown to be an independent risk factor for urethroplasty complications following hypospadias repair. Testosterone (T) administration in prepubertal males increases both penile length and circumference. Its...

Testosterone and erectile function – the debate goes on!

The most common causes of erectile dysfunction (ED) as per European Association of Urology (EAU) guidelines are: psychogenic, vasculogenic, neurogenic and hormonal. The EAU 2017 guidelines recommend measuring total testosterone (TS) level. This study is a meta-analysis of 14 randomised...

Preoperative use of testosterone prior to distal hypospadias repair

Preoperative hormonal stimulation has been utilised for >50 years in hypospadias surgery. Surgeons utilise testosterone (T) to increase penile size and glans width to try and improve clinical outcomes. However, a paucity of reliable data supporting its use has limited...

Testosterone supplementation after prostatectomy – journey from bad to good

The role of androgens in the pathogenesis of prostate cancer is quite complex and is not entirely clear yet. Despite several reports suggesting testosterone use is safe in patients diagnosed with prostate cancer, many clinicians are still reluctant to use...

Androgen insensitivity in patients with proximal hypospadias

A number of surgeons use preoperative androgen stimulation for a period of time prior to hypospadias surgery. The aim is to increase glans circumference, penile length and improve prepucial vascularisation pre-surgery. Data confirming the results of these aims is scarce....

Understanding gender differences in nephrolithiasis

Rates of nephrolithiasis are higher in males than females. The cause for this remains unclear, however animal models have demonstrated an association between sex steroid hormone levels and lithogenesis. This relationship in humans is less well established. This study from...

The potential of statin use in castrate resistant prostate cancer treatment

One of the mechanisms by which prostate cancer achieves castrate resistance is through de novo intratumoral production of androgens. Reactivation of androgen receptors results in promotion of cell survival and proliferation pathways despite castrate serum testosterone levels. As androgen synthesis...

Buccal grafts for urethroplasty in pre-pubertal boys

Buccal mucosa graft (BMG) is often used as the primary graft in complex hypospadias surgery. It is not clear what the response of this BMG is during puberty androgen surge and whether or not differential penile growth occurs with secondary...

Erectile dysfunction part II: treatment

Introduction The identification of specific risk factors associated with erectile dysfunction (ED) allows patients with mild or moderate ED to undergo a series of lifestyle changes, which may provide enough improvement in the erectile function to avoid pharmacotherapies. Cessation of...

Men’s Health in Primary Care

Men’s health has lagged behind its female equivalent as a specific medical subject but, over the past decade, campaigns by men’s health groups have started to give it the prominence it deserves. This book sets out to be a comprehensive...

Characteristics of testicular tumours in prepubertal children

It is well known that testicular tumours in children occur in one of two peaks. Firstly, in the first four years of life where a third to half of these tumours are benign and secondly during puberty where there is...
