What is an indication of hypospadias that should be noted at birth?

The indication of hypospadias that should be noted at birth is the urethral opening being located on the underside of the penis. Hypospadias is a congenital condition where the urethra does not fully develop, resulting in the opening being positioned on the ventral (underside) aspect rather than at the tip of the penis. This condition can vary in severity depending on how far down the shaft the urethral opening is located, and recognizing this anatomical variance at birth is crucial for proper diagnosis and timely intervention.

Other options listed do not relate to the condition of hypospadias. The presence of extra fingers refers to a condition known as polydactyly, which is unrelated to the penile anatomy. The absence of a belly button might suggest other congenital abnormalities but has no connection to hypospadias. Delayed passage of meconium is often associated with gastrointestinal issues and does not pertain to hypospadias. Hence, the presence of the urethral opening on the underside of the penis is the key characteristic to note at birth for this condition.
