Men are the weaker sex
Date:3/31/2009

Nurses in the maternity ward often say that a difficult labor is a sign of a baby boy. Now, a Tel Aviv University study provides scientific proof that a male baby comes with a bigger package of associated risks than his female counterparts.

In a study of 66,000 births, Prof. Marek Glezerman, chairman of the Department of Obstetrics and Gynecology at the Sackler School of Medicine, Tel Aviv University, together with Dr. Yariv Yogev and Dr. Nir Melamed, found that while girls were at a higher risk for restricted growth in utero and for breech presentation at birth, risks associated with boy fetuses were more abundant.

"Pregnancies with a male fetus are more often complicated," says Prof. Glezerman. "They're more likely to result in a premature rupture of the embryonic sac and suffer from premature delivery. And those male fetuses which make it to term," he continues, "are more likely to suffer from excessive growth in the uterus, making delivery more difficult and leading to more cesarian section deliveries."

Study Helps Doctors See the Bigger Picture

In a study presented to the Israel Society for Gender Based Medicine, researchers concluded that male fetuses come with "a higher association of risks," but note that the findings should be viewed in the proper light. "Boys are riskier to an extent," says Prof. Glezerman, but pregnancies involving boys should not be classified as "high-risk" for that reason alone. It's only one factor for doctors to consider when looking at the whole picture, he says.

"But in general, boys are more vulnerable in their life in utero, and this vulnerability continues to exist throughout their lives," says Prof. Glezerman, an expert in gender-based medicine. "Men are known to have a shorter lifespan, are more susceptible to infections, and have less chance of withstanding disease than women. In short, men are the weaker sex."

This new evidence, Prof. Glezerman notes, con
