Research indicates that male babies are more likely to be born after their due date.
Due Dates and Gender: A Closer Look
A study of over 656,000 pregnancies showed that male babies had longer gestations, increasing their likelihood of being born past the due date. This doesn't mean all male babies are born late, or that no female babies are born late; it simply highlights a statistical trend. The due date is an estimate, and it's common for babies to arrive before or after this date.
- Factors affecting delivery timing: While gender plays a role, other factors influence when a baby arrives. These include:
- First-time pregnancies
- Maternal age (being over 30)
- Clinical obesity
It's crucial to remember that the due date is merely a prediction. Many babies are born within a range of weeks surrounding their estimated due date.
Understanding Due Dates
It's important to understand that a due date is a calculated estimate, not a precise prediction. A pregnancy lasting beyond 42 weeks is considered post-term or overdue. However, even within normal gestational ranges, birth can occur before or after the due date.

This information helps clarify that while male babies show a statistical tendency towards later births, it is not a definitive rule. Many other factors influence delivery timing.
