Brothers gay

Fraternal birth order, also known as the older brother effect, has been correlated with male sexual orientation, with a significant volume of research finding that the more older brothers a male has from the same mother, the greater the probability he will have a homosexual orientation.

If you have five older brothers, your chance of being gay is about 8% — so, four times the baseline probability.

Studies have found that a man without older brothers has about a 2 percent chance of being gay, but one with four older brothers has a 6 percent chance.

In cross-analyzing data from 10 scientific studies with more than 5, subjects, researchers found that men with older brothers were 38 percent more likely to identify as gay.
