Which of the following is a more common feature in male fetuses than in female fetuses?

Pyloric stenosis is indeed a condition more commonly observed in male fetuses compared to female fetuses. This condition occurs when the pylorus, the opening from the stomach into the small intestine, becomes narrowed, leading to projectile vomiting and dehydration in infants. The male-to-female ratio for pyloric stenosis is significantly skewed, with males affected more often, reported to occur approximately 3 to 5 times more frequently than in females.

The formation of certain congenital conditions can have variations based on sex due to genetic and hormonal influences. For example, clubfoot, anecphaly, and congenital hip dislocation do not show such a strong gender preference when considering their prevalence. While some of those conditions may have slight gender differences in occurrence, they are not as markedly faced as pyloric stenosis, making the latter the more recognized male-predominant condition in fetal development. Understanding these sex differences in congenital anomalies is essential for genetic counseling and managing developmental issues in newborns.
