Dick Swaab, professor of neurobiology at Amsterdam University, says drinking and taking drugs lower a child’s IQ. Bad enough.
But more remarkably he says synthetic hormones, amphetamines and smoking (including marijuana) increase the likelihood of girls being born lesbian or bisexual.
Dick says a baby boy with older brothers increases the chance the little guy will choose lighter loafers later in life. Dick theorizes the syndrome's linked to the mother’s immune system which ravages male hormones more ferociously with each newborn son in the litter.
Prof Swaab says research is pinpointing the role of genes, environment and what mom does during her pregnancy as co-important factors in making a gay world even gayer.
