Webbed penis, also known as penile scrotal fusion, refers to the fusion of the scrotal septum skin with the ventral skin of the penis, so that the penis and scrotum are not completely separated, and the penis cannot be straightened and lengthened when erect, and urination cannot be ejaculated before. Most of them are congenital malformations, a few of them are secondary to circumcision or other surgical removal of too much skin on the ventral side of the penis. Most do not have abnormal urethral development. About 3.5% of hypospadias are complicated by this malformation. The patient, 25 years old, complained of short erection and inability to insert the vagina after erection. The patient was admitted to the hospital and was given a penile orthodontic operation. After the operation, the appearance of the patient’s penis improved well and the length of the penis could reach 11 cm after erection.1.
