Who Develops Faster, a Boy or a Girl in the Womb?

Published in Fetal Development 1 min read

In the womb, boys develop faster than girls.

According to research, male fetuses exhibit a faster growth rate compared to female fetuses. This accelerated development can unfortunately lead to increased vulnerability to undernourishment. Here's a breakdown:

  • Boys grow faster: Studies show that male fetuses tend to have a higher growth velocity than female fetuses.
  • Risk of Undernourishment: Due to their rapid growth, boys are more susceptible to becoming undernourished in the womb.
  • Long-term Health Implications: Fetal undernutrition can result in small size at birth and an increased risk of cardiovascular disorders, such as hypertension, later in life.
Gender Development Speed Risk of Undernourishment Potential Health Implications
Boy Faster Higher Cardiovascular disorders (e.g., hypertension)
Girl Slower Lower

This information highlights the importance of adequate maternal nutrition during pregnancy to support the healthy development of both male and female fetuses, especially considering the faster growth rate of boys.
