Fig 4. Penis with the loosened foreskin replaced over the glans. Surgical methods range from the complete removal of the foreskin to more minor operations to relieve foreskin tightness: Dorsal slit (superincision) is a single incision along the upper length of the foreskin from the tip to the corona, exposing the glans without removing any tissue.
The area on the underside of the glans, where the foreskin is attached, is called the frenulum. The rounded base of the glans is called the corona. The inner surface of the foreskin and corona is rich in sebaceous glands that secrete smegma. The structure of the penis is supported by the pelvic floor muscles. Anatomical diagram of the penis
The frenulum is the highly vascularized elastic band of tissue located on the underside of the glans that connects the foreskin to the head of the penis. The frenulum is supple enough to allow the retraction of the foreskin over the glans and pull it back when the erection is gone. [18] In flaccid state, it tightens to narrow the foreskin ...
In men who are not circumcised, it also connects the foreskin to the glans and the ventral mucosa. [1] [2] In adults, the frenulum is typically supple enough to allow manual movement of the foreskin over the glans and help retract the foreskin during erection. [3] [4] In flaccid state, it tightens to narrow the foreskin opening. [2]
In some cases the foreskin may become swollen as a result of paraphimosis (foreskin trapped behind the glans) or other conditions such as severe balanitis. Should reduction of the swelling by conservative methods be unsuccessful, a dorsal slit is a common intervention of choice since circumcision is almost always excluded in such cases.
In infancy, the dartos fascia operates as a one-way check valve at the tip of the foreskin, allowing urine to pass out, but prohibiting the entry of foreign matter and pathogens. There is an increase in elastic fibers with increasing maturity that allows the foreskin to become retractable by adulthood and glide freely back and forth.
English: In this video is demonstrated how a foreskin of an uncircumcised penis glides over the glans penis during masturbation. The video is taken from different angles. The male (age 35) seen in this video moves his foreskin back and forth over his erect glans penis by three fingers or by whole hand, no lubricant is used.
The penile raphe is a visible line or ridge of tissue that runs on the ventral (urethral) side of the human penis beginning from the base of the shaft and ending in the prepuce between the penile frenulum.
