The most typical symptom of hypospadias in boys is that the opening of the urethra is not in front of the glans, causing the boy to be unable to urinate normally standing up and needing to urinate in a sitting position. There are four typical features: abnormal urethral opening, deformity of the penis flexing ventrally, normal prepuce on the dorsal side of the penis, lack of prepuce on the ventral side of the penis, lack of normal development of the urethral corpus cavernosum, and a fibrous strip from the penile tether to the urethral opening without a normal urethra. For hypospadias in boys, early detection and early surgery are necessary to effectively restore normal standing urination and normal sexual function and behavior in adulthood.
