What is the tendon connecting the foreskin?

The tendon that connects the foreskin to the foreskin is usually referred to as the penile frenulum, a longitudinal band of fibrous tissue located on the ventral side of the penis.

1. Penis frenulum structure

The penile frenulum is an elastic fiber tissue that connects the glans to the inner plate of the foreskin. It is triangular or cord-shaped and has the function of fixing the position of the foreskin and limiting retraction. It is rich in nerve endings, sensitive to sexual stimulation, and can adjust the range of foreskin movement during erection. This structure is formed by the differentiation of the genital tubercle during embryonic development and gradually becomes finalized with growth and development after birth.

2. Physiological functions

The penile frenulum mainly maintains the covering and protective function of the foreskin in the non-erect state and prevents excessive retraction of the foreskin. It can buffer the impact of friction during sexual behavior and participate in regulating the conduction of sexual pleasure. This structure is tight during childhood and naturally relaxes as puberty develops. Some people have a short frenulum, which may affect the normal erection angle of the penis.

3. Abnormal situations

Frenulum tears are often caused by violent stretching during sexual intercourse, manifesting as sudden pain and bleeding. A frenulum that is too short may limit the erection angle and cause pain during intercourse. Congenital absence of the frenulum is rare and often associated with hypospadias. If you have leukoplakia or induration of the frenulum, you should be wary of lesions such as lichen sclerosus, which may affect tissue elasticity.

4. Medical treatment

If the frenulum ruptures and bleeds, compression is needed to stop the bleeding. In severe cases, suture repair is required. When the frenulum is too short and affects its function, frenulum lengthening or frenulumplasty may be considered. Topical antibiotics such as mupirocin ointment need to be used for combined infections, and ketoconazole cream can be used for fungal infections. Suspected cancer requires biopsy to confirm, and self-medication is prohibited.

5. Daily care

Keep the area clean and dry and avoid violent pulling. Choose loose-fitting underwear to reduce friction and lubricate thoroughly before sex. Frenulum abnormalities detected in childhood should be observed until adolescence without premature intervention. After the operation, you need to use Kangfuxin Liquid according to the doctor's instructions to promote healing, and review the recovery regularly to evaluate the condition.

Daily attention should be paid to observing whether the penile frenulum is red, swollen, painful or abnormally thickened, and excessive cleaning and use of irritating products should be avoided. If you experience persistent discomfort, bleeding, or impact on urinary function, you should go to a urology department for evaluation in a timely manner. When minors develop relevant symptoms, parents should avoid handling the situation on their own and let a professional doctor determine whether intervention is needed.
