British researchers may have found gene that influences people to lose their virginity early
British researchers said they have probably detected a gene that could be linked to the age at which people lose their virginity. The research might sound surprising for many but the research team has seriously evaluated the gene involved (CADM2) for the current project and the age at which study participants had sex for the first time. Though no single genetic variation can affect the behavior entirely, the group of British researchers said that the gene pattern found by them can account for a notable amount of the difference when people lose their virginity.
The team has reported in the journal Nature Genetics that the same genes are also linked to not just risk-taking behavior, but also the number of children people will end up having and how irritable they are. As a whole, they associated 38 distinct genes to the age of a person when he has sex for the first time.
John Perry, a senior investigator at Britain's Medical Research Council who was part of the study, said, “While social and cultural factors are clearly relevant, we show that age at first sexual intercourse is also influenced by genes which act on the timing of childhood physical maturity and by genes which contribute to our natural differences in personality types”.
Perry added that one example of the same is a genetic variant in CADM2, a gene responsible for brain cell connections and brain activity, which they have discovered linked to a strong probability of possessing a risk-taking personality. Perry said it is also associated with an earlier age at first sexual intercourse and higher number of children during lifetime.
The team performed a genome-wide association study a large-scale search through the human body’s all 20,000 genes.
The study was based on three distinct databases, including Britain's Biobank, where over 120,000 men and women have submitted samples and filled in-depth questionnaires; Iceland's population-wide genetic database of 241,000 people and roughly 21,000 women who participated in the US Women's Genome Health Study.
