LONDON — Researchers have found that differences in DNA could account for a quarter of the variation in the age at which people lost their virginity, with other factors, among them religious beliefs, family background and peer pressure, making up the rest.
The study out of Cambridge University in the UK found this can lead to poorer educational outcomes and higher risks of disease.
Researchers at Cambridge University analysed genetic data from more than 125,000 people, aged 40-69, from the UK Biobank, and found that genetics played a role in the age at which a person first engages in sexual intercourse — in other words, the timing of puberty.
They additionally found that a man’s identity, such as, a high risk-taker, plays a role.
“We were able to calculate for the first time that there is a heritable component to age at first sex, and the heritability is about 25%, so one quarter nature, three quarters nurture,” said John Perry, an expert in reproductive ageing and related health conditions at Cambridge University.
The author of the report, Dr Ken Ong, a pediatrician at Cambridge University specialising in epidemiology, said based on the findings, doctors should consider managing the onset of puberty if it arrives particularly early.
“Our current findings show that if we can in future help to avoid inappropriate early physical maturation, these will have benefits both in the short term on educational and sexual health, as well as in the long term,” Dr Ong said.
Dr Ong said the study showed that for the first time physical characteristics of an individual played a large part in when they first had sex.
“Our study now shows for the first time that particularly those with certain physical characteristics, larger body size, those who are maturing physically earlier, are more vulnerable to such influences,” he said.
Dr Ong said genetic factors that influence a person’s personality also played a role.
“People who are more risk-taking, those who are maybe socially agreeable, [have] less irritable temperaments,” he said.
