If you and your pregnant wife want baby girls, gently advise scientists, subject every neighborhood cat to the Spanish Inquisition and burn all of them on the stake. Because there’s something about cats –a parasite, to be specific — that makes only male embryos to survive.

…According to scientists women infected with a common cat parasite give birth to more sons than daughters.

The parasite, toxoplasma, infects around 15% of Britons, but up to 80% of the population in some countries. It is spread by contaminated cat faeces, but also lurks in uncooked pork and beef.

Researchers in the Czech Republic collected medical records from 1,803 newborn babies between 1996 and 2004 and checked them for information on the mothers and babies including gender, the number of previous pregnancies, and the mother’s levels of toxoplasma antibodies.
