There has been recent interest in the use of botulinum neurotoxin (BoNT) in the field of Andrology, whereby it has been investigated in the treatment of penile retraction and premature ejaculation. Ler mais
Erectile dysfunction (ED) is a socioeconomic problem.There are several options for its management including intra-cavernosal injection (ICI). Ler mais
Botulinum toxin type A (BoNT-A) has been used to treat several striated and smooth muscle disorders. During the past year, human and animal studies conducted in Egypt and Canada by two different groups of investigators have suggested a possible role for the intracavernosal injection of BoNT-A in the treatment of erectile dysfunction (ED).

Hidden penis, inconspicuous and concealed penis are synonyms for the same entity "buried penis" where the penile shaft is hidden below the surface of the prepubic fat to an extent that gives an impression of a short penis, despite corporeal length being normal. Ler mais
Penile curvature (PC) is bothersome to the patient. PC is either congenital or acquired. In most of the circulatory system, blood flows in a laminar profile with minimal energy expenditure. When a fluid passes in a curved tube, the laminar profile is disturbed and changed into a turbulent flow. It increases the energy expenditure and reduces the flow. Turbulent flow may have a role in the development of an atherosclerotic plaque and in localizing its site. The aim of this research was to study penile hemodynamics before and after correction of PC. This prospective study included 20 participants, with PC more than 30°. For each participant, preoperative color duplex doppler ultrasonography (CDDU), correction of the curvature using 16 dot plication technique and post-operative CDDU were done. Furhtermore, arterial systolic velocity was estimated distal to the site of curvature/correction every 5 min for 25 min. The degree of curvature ranged from 30° to 90° with a mean of 55±18.98. Comparative study between the preoperative and post-operative data proved a significantly higher postoperative peak systolic velocity distal to the site of correction, whereas CDDU data had insignificant differences. We concluded that correction of PC is associated with improvement of penile arterial blood flow distal to the site of correction. Ler mais
Erectile dysfunction (ED) is the most frequently treated male sexual dysfunction worldwide. ED is a chronic condition that exerts a negative impact on male self-esteem and nearly all life domains including interpersonal, family, and business relationships. Ler mais
Erectile dysfunction is a common clinical entity that affects mainly men older than 40 years. In addition to the classical causes of erectile dysfunction, such as diabetes mellitus and hypertension, several common lifestyle factors, such as obesity, limited or an absence of physical exercise, and lower urinary tract symptoms, have been linked to the development of erectile dysfunction. Substantial steps have been taken in the study of the association between erectile dysfunction and cardiovascular disease. Erectile dysfunction is a strong predictor for coronary artery disease, and cardiovascular assessment of a non-cardiac patient presenting with erectile dysfunction is now recommended. Substantial advances have occurred in the understanding of the pathophysiology of erectile dysfunction that ultimately led to the development of successful oral therapies, namely the phosphodiesterase type 5 inhibitors. However, oral phosphodiesterase type 5 inhibitors have limitations, and present research is thus investigating cutting-edge therapeutic strategies including gene and cell-based technologies with the aim of discovering a cure for erectile dysfunction.

There is no universal gold standard diagnostic test to differentiate psychogenic from organic erectile dysfunction (ED). Cavernosography/cavernosometry has been used to evaluate veno-occlusive dysfunction (VOD) in men with a proposed organic ED. Ler mais
With the worldwide increase in penile augmentation procedures and claims of devices designed to elongate the penis, it becomes crucial to study the scientific basis of such procedures or devices, as well as the management of a complaint of a small penis in men with a normal penile size. Ler mais
