Congenital genital shortness in newborns is mainly considered to be related to chromosomal abnormalities, congenital malformations, low testosterone levels and other factors.
1. Chromosomal abnormalities: such as polychromosomal malformations, poly X syndrome, etc., can lead to penile deformities and shortening in newborns.
2. Congenital malformations: such as hypoplasia of both testes and epididymis, hermaphroditic malformations, etc., which can also lead to penile deformities and shortening of the penis.
3. Low testosterone level: such as congenital pituitary underdevelopment, cerebellar malformation and other factors, can affect the production of testosterone. Testosterone has a significant role in the development of male sexual organs, such as low testosterone levels, will also affect the development of the penis.
If a newborn baby has a short penis, it is recommended to seek medical treatment as soon as possible.
