Stress promotes female births

Research reported in the Royal Society biology letters indicates that when a conceiving mother is under stress there is more chance that the foetus resulting will be female. The research focussed on statistics in tropical climates but the conclusion focusses on environmental stress conditions. Female foetuses are more resilient than male foetuses. This appears to be increasingly well supported conclusion, not just one of Tom’s pet theories. So if you want a girl, get stressed and if you want a boy chill out!
