While the male urinary or urethral meatus carries both urine and semen, the female urinary meatus only carries urine. Sometimes, the opening forms in a problematic area, such as the bottom of the glans penis. This condition is called hypospadias, while the opposite condition, in which the meatus is located on the bottom of the glans penis, is called epispadias. Some males experience urethral damage during circumcision. If scar tissue forms near the meatus, it can become inflamed by clothing or diapers.
