Birth order is another known input for male homosexuality.[1][2] For every older biological brother, the chances of being born gay go up substantially. But the mechanism isn't known yet. A number of other objective measurements also change with birth order. Parent genetics alone aren't enough.

Interesting. Then by that rationale, since families used to on average produce vastly more children per closed family unit, the amount of gay children in total should be dropping?
