Several common abnormalities of male lower body
(1) Phimosis: The skin of the penis of normal men is thin, and the skin near the head of the penis is folded inwards into a double layer, covering the penis, called the foreskin. If the foreskin opening is narrow, the tightly wrapped penis head cannot be turned upside down to reveal the penis head. When a child is born, there is adhesion between the foreskin and the head of the penis called congenital phimosis. Another type of acquired phimosis is secondary to foreskinitis of the penis head, which is caused by the formation of scar contracture at the foreskin.
(2) Concealed penis: refers to excessive fat in the pubic bone, and insufficient skin of the penis attached to the penis body, so that the penis is hidden in the skin of the pubic bone. The disease may be accompanied by penile head-type urethral fissure, and the urethral groove on the dorsal side of the penis can be touched through the skin of the penis.
(3) Penile scrotum translocation: also known as anterior penis scrotum. It is because the scrotum has grown to the front of the penis, and it cannot survive because of other serious deformities, so it is rare in the clinic. Complete scrotal translocation is rare, and partial penile scrotal translocation is often accompanied by hypospadias.
(4) Torsion of the penis: From the anatomical structure of the penis, it can be seen that the penis is composed of two penile corpora cavernosa on the dorsal side and a urethral corpus cavernosum on the ventral center. The degree of torsion of the penis is determined by the degree of unbalanced development of the cavernous body of the penis.
(5) Webbed penis: A thin skin from the scrotum continues to the ventral side of the penis, and the penis and scrotum are fused.
(6) Duplicate penis: Including the bifurcated penis, complete duplication of the penis and another ectopic penis, the incidence of bifurcated penis is high. Repeat penis can be limited to the penis head or include the entire penis body.
(7) No penis: The patient is not born with a penis, and the urethra is opened near the perineum, near the anus, or even in the rectum. The disease is very rare, one in about 2 million newborn boys.
(8) Big penis: As the name implies, compared with people of the same age, the penis is too large and is called the big penis. In general, the normal adult penis is 7 to 10 cm, and it can be doubled when erect. The disease mostly occurs in precocious puberty, congenital dementia, dwarfism, pituitary hyperfunction and adrenal hyperfunction.
(9) Small penis: Normal male neonates have an average penis length of 3.5 to 7 centimeters, and the small penis is less than 1 centimeter. When entering puberty, the male penis is a child.
(10) Congenital penile curvature: the urethral corpus cavernosum located on the ventral side of the penis becomes shorter, causing the penis to bend toward the ventral side.
