Short foreskin tie may be congenital dysplasia, or it may be caused by acquired factors such as circumcision, trauma and so on. 1. Congenital short tether: congenital developmental deformity can cause short foreskin tether, which may pull the penis after erection, causing it to bend downward, and may also cause pain during sex, which needs timely surgical correction to loosen the tether. 2. Circumcision surgery: circumcision may be too much cutting of the tethered ligament, which may cause complications such as torn tethered ligament and short tethered ligament after healing, and may also cause erectile dysfunction. 3. Trauma: localized external force causes damage to the tethered ligament, and in the process of recovery and healing, scar formation may cause the tethered ligament to become shorter. A short tethered cord may cause erectile pain and have a certain impact on sexual life. Therefore, it is recommended that patients with short ligaments should consult a doctor in time and take active treatment in order to avoid delaying the condition.
