Which nerve is responsible for sensation to the suprapubic area and mons pubis?

The iliohypogastric nerve is responsible for sensation in the suprapubic area and the mons pubis. This nerve originates from the first lumbar nerve root (L1) and provides sensory innervation to the lower abdominal wall, including the region above the pubic bone, which encompasses the suprapubic area and the mons pubis.

The iliohypogastric nerve travels parallel to the iliac crest before it divides into a lateral branch that supplies the skin over the lateral aspect of the abdominal wall and a medial branch that provides sensation in the suprapubic area. This innervation is crucial for maintaining proper sensory function in the lower abdomen and contributes to the overall sensation in the area.

In contrast, the ilioinguinal nerve primarily innervates the skin of the groin and part of the medial thigh, while the genitofemoral nerve supplies the genital area and the upper anterior thigh. The internal pudendal nerve, on the other hand, mainly provides sensory and motor innervation to the perineum and external genitalia but does not have a role in sensation to the suprapubic area.

Thus, the specificity of the iliohypogastric nerve for the suprapubic region underscores
