Regular sex makes women more fertile

If you want to get pregnant, you have to have sex. Logical. But what about the sex that women have outside the fertile days? Does it affect the fertility of the body? It is a puzzle that has long occupied scientists. Now there is an answer.

Sex boosts our immune system

For the first time, researchers from Indiana University in the US have found that sexual activity prepares the women's immune system for pregnancy.

Accordingly, women's bodies respond to regular sex by their immune system produces more antibodies (immunoglobulin G) and TH2 cells. Thus, the body is not only prepared for a possible pregnancy - but also increases the likelihood of conception. According to the results, this effect does not occur in women who rarely have sex.

Helper cells prepare for foreign bodies such as sperm and the fetus

But why does our immune system do that at all? "The female body has a tricky dilemma," said Professor Tierney Lorenz, lead author of the report, in a press release. "In order to protect himself, he has to defend himself against foreign invaders, but if he applies this logic to sperm and a fetus, he can not get pregnant." The change in the immune system seems to be the answer to that problem. "

Because the TH2 cells help to accept the sperm and the fetus as "friendly" invaders. The special immunoglobulins G, in turn, fight against pathogens and are the only antibodies that also enter the child's blood through the mother cake and protect against infections after birth.

Perfect conditions to get pregnant.

Regular sex is worth it

"It is a common recommendation for couples who want to have a child to have regular sex - even in the infertile days," said Lorenz. And apparently you were exactly right.

"This study is the first to show that sexual activity leads to a change in the body's immune system that actually promotes conception."
