A new study from researchers at Indiana University has shown that sexually active women have a much higher chance of getting pregnant than those who remain abstinent - here's why.
The study also revealed that sexually active women underwent changes in immunoglobulins, with immunoglobulin G more common during the luteal phase, and immunoglobulin A levels higher during the follicular phase. Surprisingly, these shifts in antibody levels were not observable in women who refrained from sexual activity.
According to Professor Lorenz, the study shows that the immune system does in fact respond to increased levels of sexual activity. It is possible that sexual activity lets the body know that pregnancy is possible, allowing it to make the necessary immune changes in advance.
Both of the papers published by the Indiana University researchers help shed light on the idea that the immune system is a lot more responsive to our environments than we previously thought. They can also explain previous researcher that outlined these immune shifts in women. When considering how sexual activity prepares the body for the possibility of conception and pregnancy, it makes sense that the immune system would generate one of the first responses. The research could help doctors treat patients with immune disorders, and could provide a more solid foundation for the recommendation of sexual activity for increasing the chances of conception.
