Scientists have said that men with older brothers are more likely to become gay. Researchers realized this

after studying the data.

A team of specialists from the University of Toronto,Institute of Sexology and Sexuality Medicine, Charité Clinical Complex and the University of Lethbridge published its findings in the journal Proceedings of the Royal Society B.

The researchers analyzed ten unrelated papers that described the sexual orientation of 5,400 men and included information about their siblings.

As a result, scientists found that men who havethere was an older brother, 38% more likely to be gay than those who did not have a brother. In addition, the likelihood of homosexuality increased with the number of older brothers. As for women, the researchers did not find such a correlation among them.
