War between the sexes begins before twins' birth, TAU researchers say
Date:4/7/2008

The battle of the sexes may begin in the womb, researchers from Tel Aviv University believe. And it may have troubling consequences a male twin can compromise the health of his twin sister before she is born.

In a new study recently published in the journal Pediatrics, the researchers analyzed the incidence of complications, such as respiratory distress syndrome, found in pre-term twins. When born premature, girls who share the womb with a boy twin lost the respiratory health advantage normally seen in premature girl infants, they discovered.

The male disadvantage, the study suggests, seems to be transferred from the boy to the girl in utero, says Prof. Brian Reichman, a lecturer in pediatrics at Tel Aviv Universitys Sackler School of Medicine.

Girl Twins Lose Their Advantage

Compared to premature twin boys, premature twin girls had a 60 percent advantage. The premature twin girls tended not to develop respiratory distress syndrome and chronic lung diseases sometimes found in premature infants. This advantage was lost in infant girls with a male twin.

This new study is expected to help pediatricians better understand the health risks and outcome of premature babies.

Prof. Reichman helped analyze the data collected by the Israel Neonatal Network comprising 8,858 very low birth weight infants ( 1 to 3 pounds) born prematurely at 24 to 34 weeks' gestation. The study data covered infants born between 1995 and 2003 and included singletons, same-sex and mixed-sex pre-term twins.

Beginning in the Womb

The TAU study is somewhat unusual. Twin studies tend to focus on what happens after birth, when complicated environmental and learned behavioral factors come into play. The effects are occurring already in the uterus, says Prof. Reichman, citing studies showing that females with male twins may be more masculinized later in life.
