The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features. Anatomy of the Penis The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

This video demonstrates the establishment of uropathogenic Escherichia coli infection in a female mouse bladder through transurethral catheter instillation. The injected bacteria successfully establish a urinary tract infection within the bladder, providing a valuable platform for studying healthcare-associated diseases related to the urinary tract.

In the present protocol, a urethral stricture induction was developed in Wistar rats, followed by urethral reconstruction with a buccal mucosa graft. A retrograde urethrogram and laser Doppler assessment were performed, validating urethral reconstruction (after stricture formation) and graft placement.
FAQs
The expanded end of the corpus spongiosum enlarges during erection while helping preserve the urethral passage. This arrangement allows the glans penis to participate in reproductive function without losing its connection to urinary flow. Its anatomy therefore illustrates how erectile changes can support sexual function while maintaining the structural continuity needed for passage of urine.
Dense sensory innervation allows the glans penis to detect touch and pressure. These sensory signals contribute to sexual sensation and make the region particularly important when studying how anatomical structures participate in reproductive function. The concentration of sensory input also helps explain why changes affecting the surface may influence comfort, sensation, or clinical assessment.
The glans penis surrounds the external opening of the urethra, placing urinary and reproductive functions within the same distal anatomical region. Its erectile tissue enlarges during erection while helping preserve the urethral passage, demonstrating a structural coordination between sexual activity and the continuing anatomical pathway used for urination.
The foreskin can protect the surface of the glans penis, which is relevant when considering its sensitivity and exposure to the external environment. This protective relationship is an important part of anatomical study because it connects surface coverage with hygiene, inflammation, and infection-related considerations without separating the glans from its surrounding structures.
Clinical study of the glans penis connects normal anatomy with hygiene, inflammation, infection, and congenital or acquired anatomical conditions. Its location around the urethral opening, sensitivity, and relationship with the foreskin provide several features for examination. Understanding these characteristics helps place abnormal findings in the context of urinary and reproductive function.
A biological assessment should consider the glans penis as an integrated structure rather than examining sensitivity, urination, or reproduction separately. Relevant features include the expanded corpus spongiosum, preservation of the urethral passage during erection, dense sensory innervation, and foreskin protection. Together, these features support investigations of male reproductive anatomy, sexual sensation, urinary function, and related conditions.
