A study finds genetics explain 15% of why some people have never had sex, linked to loneliness and social factors.
A University of Queensland study of over 400,000 UK and 13,500 Australian adults found that about 1% of people have never had sex, with genetics accounting for 15% of the variation.
These individuals often report higher loneliness, fewer social connections, and lower life meaning.
The research identified genetic links to education, income, intelligence, and traits like introversion, autism, and anorexia, but no single gene had a large effect.
Sexlessness was also associated with living in areas of high income inequality and fewer women.
The study highlights complex interactions between genes, environment, and personal factors, aiming to improve understanding of asexuality and its impact on well-being.
