Dominant, aggressive women more likely to produce sons, study finds

[NewJeffCT]

Dominant, aggressive women are more likely to have sons than daughters, scientists believe.

A study in New Zealand found a possible link between high testosterone levels in women and giving birth to boys.
The findings question the idea that the sex of babies is determined by chance.

A team led by Dr Valerie Grant of the Department of Medical and Health Sciences at the University of Auckland, found a link between high levels of the male hormone testosterone in cows' wombs and their likelihood to have a bull calf.

Don't like the Telegraph's use of "battleaxe" mothers, but I have heard this a few times now.
