S-ex has a positive effect on a person’s immune system, a medical study suggests.
A team of researchers from Indiana University recently found that se-xual activity, even during non-fertile periods, triggers physiological changes in the body that can overall increase a woman’s chances of getting pregnant.
“We’re actually seeing the immune system responding to a social behavior: se-xual activity”, Lorenz said in a statement.
Based on information and data from the study of Women, Immunity and Se-xual Health from the Kinsey Institute, the results are published in the Fertility and Sterility and Physiology & Behavior journals. They conducted a study on 30 healthy young women, accumulating data across their menstrual cycle.
Researchers similarly saw changes in immunoglobulin levels that aided in conception among the se-xually active women. Scientists have noticed the type 1 helper T cells were much more present during the follicular phase of the menstrual cycle.
Researchers followed the two groups for a longer period of time, signaling all the differences that appeared within the women’s immune system.In the study researchers found that women who are se-xually active experienced better changes in helper T cells and the proteins T cells communicate with. “The se-xually active women’s immune systems were preparing in advance of a possible pregnancy”.
According to their recent findings, having frequent se-xual inter-courses helps regulate women’s immune system, which, in turn, leads to increased fertility rates. But a new study sheds light on the relationship between those findings- and alters the second, suggesting an increased chance of fertility regardless of when a woman has s-ex.
Saliva samples were taken at four stages: menstrual, follicular, ovulatory and luteal. Immunoglobulin A antibodies reduce the movement of sperm, but immunoglobulin G antibodies fight disease and mostly leave pregnancy related developments and invaders alone. The findings could influence decisions and recommendations about how often a couple should have se-x in order to have a better chance to conceive.
It seems that the female body releases more Type 2 helper T cells when it experiences a lot of s-ex, because these help her to accept foreign bodies such as sperm and a foetus, rather than reject them as the immune system might accidentally otherwise do.
Likewise, the team explains their research could impact treatment for people with autoimmune disorders.
These shifts in immunity were not observed in se-xually abstinent women, the study found. But if it applies that logic to sperm or a foetus, pregnancy can’t occur. This is why the shift in immunity is very important for a woman to respond against this problem.
The lead author on both papers is Tierney Lorenz, a visiting research scientist at the Kinsey Institute.
Julia R Heiman, a professor in the department of Psychological and Brain Sciences, and Gregory E Demas, a professor in the department of Biology, were also co-authors on the study. A recognition that se-xual activity can cause natural fluctuations in blood tests results could be useful to physicians treating patients with immune disorders, Lorenz said.
