Efectos mnemónicos maternos prenatales sobre el sexo psíquico humano. Insuficiencia del mecanismo inmunitario: Nueva propuesta desde la tolerancia-rechazo materno-fetal

In approximately 15% of homosexual men, their phenotype is associated to the fraternal birth order. Older biological brothers induce in their mothers anti-male factors (antibodies) that interfere the brain maleness development ofyounger fetuses. This effect is seldom seen in non-right-handed men and...

This effect is seldom seen in non-right-handed men and is not seen in women. The influence of older siblings is seen in their sex ratio (SR).
