About Hypospadias

Hypospadias is a condition where the meatus isn't at the tip of the penis. Instead, the hole may be any place along the underside of the penis. The meatus (hole) is most often found near the end of the penis ("distal" position). But it may also be found from the middle of the penile shaft to the base of the penis, or even within the scrotum ("proximal" positions). Over 80% of boys with this health issue have distal hypospadias. In 15% of those cases, the penis also curves downward slightly, a condition called "chordee." When the meatus opens further down the shaft, curvature occurs in more than 50% of patients.  Read More about Hypospadias →
