**Core Concept**
Hypospadias is a congenital condition characterized by the urethral meatus being located on the underside of the penis, rather than at the tip. The condition arises from incomplete fusion of the urethral folds during embryonic development.

**Why the Correct Answer is Right**
The most common site of hypospadias is proximal to the glans, which means the urethral meatus is located on the shaft of the penis, closer to the body than to the tip. This is due to the incomplete fusion of the urethral folds during fetal development, resulting in a urethral opening that is not properly formed. In most cases, the urethral meatus is located on the underside of the penis, but it can also be found on the scrotum, perineum, or even the perineal area in more severe cases.

**Why Each Wrong Option is Incorrect**
**Option B:** Incorrect because while hypospadias can occur on the scrotum, it is not the most common site. Scrotal hypospadias is a more severe form of the condition.
**Option C:** Incorrect because perineal hypospadias is the least common form, where the urethral meatus is located on the perineal area between the scrotum and anus.
**Option D:** Incorrect because mid-penile hypospadias is a possible but less common location for the urethral meatus.

**Clinical Pearl / High-Yield Fact**
It's essential to note that hypospadias is often associated with other congenital anomalies, such as undescended testes, and may require surgical correction to ensure proper urinary function and cosmetic appearance.
