**Core Concept**
Omphalocele is a congenital anomaly characterized by the protrusion of abdominal contents through a midline defect in the navel, also known as a congenital hernia. This occurs due to a failure of the abdominal wall to close properly during fetal development.

**Why the Correct Answer is Right**
Omphalocele typically involves the herniation of intestines, liver, and sometimes the bladder or other organs through the defect. The herniated contents are usually covered by a thin transparent sac, and the condition is often associated with other congenital anomalies such as cardiac defects, renal anomalies, and chromosomal abnormalities.

**Why Each Wrong Option is Incorrect**
**Option A:** Incarceration and strangulation of the intestines are potential complications of omphalocele, but they are not the primary characteristics of the condition.
**Option B:** Omphalocele is indeed more common in males than females, but this option does not describe a characteristic of the condition.
**Option C:** Intestinal atresias are a type of congenital anomaly that can occur in association with omphalocele, but they are not a defining feature of the condition.

**Clinical Pearl / High-Yield Fact**
Omphalocele is often associated with other congenital anomalies, and a thorough evaluation for additional defects is essential in the management of this condition.

**Correct Answer: D**
