Boy-girl twins - effects of female twin's exposure to testosterone in womb

June 18, 2007 2:55am CST
Just read on the news that for twins (one boy and one girl), exposure to high levels of testosterone in the womb make the female twin less likely to marry and have children. Experts cite that facial characteristics can be changed by exposure to hormones from the other foetus. I never knew that! Interesting finding huh? Anyone knows any such twins?
