Bump or breast – which is the most accurate indicator of baby’s sex?

I can almost guarantee that if you’ve been pregnant, you’ve had the shape of your bump analysed by wielders of the philosophy that goes something like this:

If your tum is high and tight, it’s a boy. If it’s wide and low, it’s a girl.

Myth busted.

Word on the street is that its breasts, not bump, that are more accurate indicators of a baby’s sex.

Science journalist Jena Pincott is the author of a new book entitled “Do Chocolate Lovers Have Sweeter Babies – The Surprising Science of Pregnancy”, which delves into the latest medical research to approve or disprove mysteries and misconceptions surrounding pregnancy.

One of the big ones is the aforementioned bump/gender thing.

In her book, Jenna describes how women carrying girls develop larger breasts during pregnancy than women carrying boys (their bust increases by 8cm on average compared with 6.3cm for women carrying boys).


In an effort to grow to a male-sized baby (ie. larger than a girl baby), male foetuses produce more testosterone and require more energy from their mother; both of which may suppress breast growth.

Interesting, right!? But do note the word ‘may’ in the above sentence, which leaves room for error in the theory.

I can’t help but wonder if society is going to give the ‘okay’ to that act of examining pregnant women’s breasts in light of this new information. Where will we draw the line?

All I can say is that nothing surprises me anymore!
