Abstract

In aspect of the role of the glans penis, besides sexual inferiority, why do so many people want to have big glans penis? What is the role of the glans penis? There is no description about the function of the glans penis in textbooks of andrology, urology, and even anatomy. The penis is the symbol of the male and is a tool for both voiding and sexual intercourse. As a tool for voiding, the essential role of the glans penis can be easily understood based on the purpose of hypospadias repair. The glans penis maintains the straight urinary stream and protects the distal urethra. As a tool for sexual intercourse, the glans penis is a sensory organ for sexual stimuli. Glans erection elongates the underlying elastic rete ridge which exposes more underlying sensory receptors. As a tool for intercourse, the glans penis has a unique function based on its conical shape. The conical glans penis is the proper shape for vaginal dilatation and easy intromission of the penis into the vagina. If the glans size is too small compared to a thick shaft, dilatation or intromission is not so easy and effective. The conical shape of the glans penis is aids in aiming and is effective for transfer of axial cavernosal pressure to the distal tip of the penis. During erection, cushion effects of the glans penis prevent both vaginal trauma and injury of the distal penis. For these reasons, the penis cannot do anything without glans! The penis should look aesthetically normal and relevantly large with respect to the penile body and be as tumescent as the body during erection.
