Recent studies show that genes can influence the age of first intercourse and first birth by acting on both personality and physical characteristics. So in short, genetic makeup may help to determine when people lose their virginity.
Apparently, these findings matter due to the fact that "people who have sex and babies earlier appear to fare worse educationally and have poorer physical and mental health," says the co-author Ken Ong.
Researchers have previously linked the start of puberty to genetics factors, but Ong said it was not known how genes may affect the timing of first sex and when females first give birth. The new study finds a "moderate genetic component" for both, although not a direct cause-and-effect relationship.
Dr. Timothy Spector, a professor of genetic epidemiology and director of twin research at Kings College London in England explains, "Our increasing childhood obesity problems are making puberty increasingly early," said Spector, who wasn't involved in the study.
Decades ago, when puberty occurred years later, people tended to have their "First-time" later than now but gave birth later. Ong explains, "In recent years, there is on average nearly 10 years between first sexual intercourse and having your first child," Ong said.
Spector concludes on what the finding mean in day-to-day life. "The main message is that our teenage behaviors are a mix of our genes and environment."
This study is certainly one to take note of. it is very interesting how they were able to take a topic that normally would have nothing to do with genetic and brought light to the important gene factor involved in it. I personally would not full agree with the correlation that were made in regards to sex being related to poverty or lack of education. Sex, I believe is a completely isolated factor to someone's financial status or intelligence.
