In the apple snail (Pomacea canaliculata), females have an undifferentiated mass of tissue near the anus. Although this mass is called the vestigial penis, there are no signs of a hermaphroditic gonad or any structure that represents a transition from one sex to the other. Based on considerations of the steroid hormone theory of reproduction and in view of disruption of endocrine systems in mol...

A 83-year-old man presented to the urology department with a painful swelling of the glans penis. The patient was admitted from the emergency department for pneumonia and urinary tract infection two days before, and a urethral catheter was placed. Physical examination showed preputial edema and a swollen glans penis associated with an ischemia-related hemorrhagic mucosal suffusion (Fig. 1). A d...

Objective: we report here results obtained concerning analyses of the putative penis Napoléon. Methods: SEM-EDX and mtDNA on samples this are realized. Results : studies show that relatively rich in calcium phosphate, consequently “penis” is more likely a piece tendon; mt-DNA analyses, realized two samples, showed presence 16184T mutation only, confirming tendon well

Introduction. Concealed-buried penis is an acquired condition associated with obesity, challenging to both manage and repair. Urethral stricture is a more common disorder with multiple etiologies. Lichen sclerosus is a significant known cause of urethral stricture, implicated in up to 30%. We hypothesize that patients with buried penis have a higher rate of urethral stricture and lichen scleros...

Aims: To explore the combination of environmental and physical factors associated with the development of body dysmorphic disorder (BDD) related to penis size and the differences between men who are anxious about their penis size (but do not meet criteria for BDD), and men who do not report concerns about penis size. Method: Men with BDD (n = 26) were compared to those with small penis anxiety ...

RATIONALE Alveolar soft part sarcoma (ASPS) is a rare, malignant neoplasm, which mostly occurs in the upper and lower extremities. This article presents an unusual case of ASPS involving the penis of a 3-year-old boy. To our knowledge, this is the first case of ASPS in the penis of a child. PATIENT CONCERNS The patient complained of slight penile pain for 1 year and a soft tissue mass could b...

Peyronie's disease is a connective tissue disorder in the soft tissue of the penis. The underlying cause of Peyronie's disease is not well understood but is thought to be caused by trauma or injury to the penis during sexual intercourse. The purpose of the interdisciplinary cooperation between urological surgery and physics is the development of a physical simulation tool in order to give progn...
