1. Poor penis development and penals after scrotal
Poor penile development is extremely rare (only 36 cases have been reported in the literature so far), and it can be accompanied by abnormalities and abnormal intestinal tracts of urogenital organs.This abnormal is caused by obstacles in the development of external genital embryo. At present, there is no satisfactory drug or handwood treatment that can make its penis have a complete function. Therefore, it should be decided to determine the gender as women and remove their testicles with surgery., Practical vaginal formation.Estrogen began in adolescence to promote the formation of female habits and second sexual characteristics.
The penis (that is, the "penis" after the scrotum), its performance is very similar at the beginning as the penis development is very similar.There were 15 patients with penile patients who had been reported in the literature.Such patients can also be accompanied by urethral abnormalities: the penis may be normal in dissection, but its position is abnormal.This may also reflect different degrees of embryo.For some diseases, application surgery may return the penis in the front of the scrotum.
2. Double penis
Double penis is a rare male external genital abnormalities. It is estimated that only one double penis appears for each 5.5 million people.Wilson quoted 108 patients in a review in 1973.The typical double penis patients have only one penis function and urethra. Therefore, only after the patients are checked in detailed urology and clarifying the urethral opening, they should take appropriate surgical treatment.

Although many parents are very concerned about the size of their children's penis, in fact, small penis is not common.Strictly speaking, the small penis is formed in the embryo, which is mainly manifested as abnormal size, not the abnormality of the shape.The position of the urethra of the small penis is normal, which can distinguish the head and body of the penis; the size of the testicles may be normal.The cause of the small penis is unclear, but sometimes it seems to be related to insufficientrogens during the 4th to 9 months after pregnancy.In some cases, small penis can also appear in other diseases. These diseases are manifested as abnormalities of hypothalamus or pituitary (such as brainless deformity, congenital pituitary, such as Prader-Willi syndrome, Kallman syndrome and Kallman's syndrome and Kallman family syndrome and Kallman's syndrome andMECKEL syndrome) or testicular abnormalities, or chromosomal abnormalities; other small penile patients can also be seen in healthy babies.
