- A relationship between handedness and sexual orientation has been suggested by a number of researchers, who report that heterosexual individuals are somewhat more likely to be right-handed than are homosexual individuals. The relationship between handedness and sexual orientation has been suggested within both sexes and may reflect the biological etiology of sexual orientation; work by Ray Blanchard has linked the relationship to the fraternal birth order effect, which suggests that a man with several older biological brothers is more likely to be homosexual. The psychologist and a team of researchers weighed in on the relationship to homosexuality and concluded: Many studies in the 1980s and 1990s had asked whether there was any relationship with handedness, and we, like others, had concluded that there was not. However, a meta-analysis of 20 studies, including our own, with a grand total of 6182 homosexual men altered that situation, male homosexuals having a significantly higher likelihood of being left-handed. The earlier studies had mostly failed through being too small, a typical study having about 300 homosexual men, and hence being under-powered. That was later confirmed in the large BBC Internet study of sex and sexuality, where 4616 male homosexuals showed a significant excess of left-handedness, with a similar effect found in the 2008 female homosexuals. — McManus, Chris, "Half a century of handedness research: Myths, truths; fictions, facts; backwards, but mostly forwards", Brain and Neuroscience Advances (2019) (en)
- Связи между преобладающей рукой и сексуальной ориентацией исследовались множеством ученых, которые сообщают, что гомосексуальные люди, в отличие от гетеросексуальных, имеют большую вероятность не быть праворукими. Установлено, что отношения между преобладающей рукой и сексуальной ориентацией существуют в пределах обоих полов и, возможно, отражают биологическую этиологию гомосексуальности. (ru)
