Feisty females are more likely to give birth to boys than girls

London - If you're an expectant mother who likes to stand up for yourself, you could soon be cuddling a newborn son.

Feisty women are more likely to give birth to boys than girls, according to scientists.

High levels of testosterone in the womb - apparently evident in more aggressive women - provide a much better environment for the sperm coded to produce boys, they claim.

But fiery females whose hearts are set on a daughter shouldn't throw out those pretty pink baby dresses just yet. So far the correlation has been proved only in tests on animals.The scientists who carried out the research, however, expect the same outcome will be seen in humans.

And those girls with an aggressive streak won't be the only ones expecting boys.
