Research has shown that more sex contributes to a healthier pregnancy and more successful IVF. These claims have to do with the way a woman's body has evolved over time and with the immune system.
The research states that women who have regular sex with the same partner at least three months before conception have a lower risk of getting pre-eclampsia - a condition that leads to serious complications for the unborn child, and in rare cases can be life-threatening for the mother.
Professor Sarah Robertson from the University of Adelaide said that preeclampsia occurs in cases where sexual contact with the baby's father is limited before conception and is associated with insufficiently strong immunity of the mother.
"The key factor is that couples have regular sex for at least three months before conception. Among women who became pregnant during the first sexual intercourse with the partner/father of the baby, the risk of preeclampsia was 22 percent, which is three times higher than the average. These mothers gave birth and very low birth weight babies," Robertson said.
Studies have shown that regular sex also helps the IVF treatment to be more successful, i.e. that the fetus is received faster.
"A study done on Australian and Spanish couples showed that the success of IVF treatment was 50 percent more successful if the couple had sex in the days before the treatment," said Robertson.
Scientists are not completely sure why the immune system has such a connection with reproduction, but they believe that it has to do with a woman's physical genetic characteristics, reports klix.ba.
