The reason why a baby born with hypospadias is caused by embryonic dysplasia may be related to a viral infection or a drug taken by the pregnant woman during pregnancy, or it may be related to some environmental pollution, but the specific cause needs to be seen in a hospital to clarify the cause. Hypospadias is a congenital defect in which the opening of the urethra is abnormally positioned in males, and is a common malformation in the pediatric genitourinary system. Most children with hypospadias will also have a ventral curvature of the penis. Since this disease can easily lead to abnormal position of the urethral opening and curvature of the penis, it may affect the normal urination of the child and the sexual life of the adult, so surgery is needed after the diagnosis of this disease, and the purpose of surgery is to restore the function of the fetal penis to urinate and the function of sexual intercourse in the adult.
