Occult penis: It is a congenital developmental abnormality, due to the abnormal attachment of the muscle fiber fascial layer of the lower abdominal wall to the penis body, binding the penis outward, resulting in the penis skin not developing well and abnormal attachment to the penis body, and the encapsulation cannot be relieved, making the penis short in appearance and cone shaped. Surgery is required, and the best time for surgery is 3-5 years old. Buried penis: It is an acquired abnormality in the appearance of the penis, which is due to obesity and poor penile exposure caused by a thick prepubic fat pad. It is not treatable by surgery. The best treatment option is weight loss. Webbed penis: also known as penile scrotal fusion, is a congenital condition in which the skin of the mid-scrotal suture fuses with the ventral skin of the penis, leaving the penis and scrotum not completely separated. Scar-bound penis: It is due to repeated inflammation, trauma or inappropriate surgery to the formation of foreskin scar, which affects the glans exposure. In some severe cases, it affects urination and penile erection. Surgical treatment is required. Micropenis: It is a congenital developmental abnormality that refers to a penis with a drawn length (SPL) less than 2.5 standard deviations (SD) of the average drawn length of the penis for the same age, a chromosome of 46XY, a normal ratio of penile circumference to length, and the absence of any other penile deformity (e.g., hypospadias). The prevalence in the United States is 1.5/10,000, and in our country, the prevalence is not yet available. According to endocrine abnormalities, micropenis can be broadly classified into three main categories, hypogonadotropic hypogonadism (pituitary/hypothalamus failure) + hypergonadotropic hypogonadism (primary testicular failure) + idiopathic hypogonadism (normal hypothalamic-pituitary-testicular axis function), with complex treatment options.
