Stop Saving Yourself for When She’s Fertile

Yes, you heard me. The common misconception about conception is that couples should be abstinent outside of the woman’s fertile period so that the man can “save himself” for when her eggs are ready.

According to the latest study by Indiana University scientist Tierney Lorenz, it is important for couples trying to conceive to have more frequent sex outside of the woman’s ovulation.

The reason behind this evidence comes down to the relationship between the woman’s immune system and her reproductive system. It is the immune system’s job to keep out foreign intruders (for example, sperm cells) so she stays healthy and can avoid disease. As we all know, the reproductive system’s job is to welcome the sperm cells, so now there’s a conflict.

All of this ties together with the woman’s menstrual cycle, where evidence shows that women’s tendency to get sick increases during ovulation. This is direct proof of this relationship between these two systems.

Lorenz main conclusion was that when women have sex outside of their ovulation period (when their immune system is in more control), they are training their immune system to be okay with the intrusion of sperm cells, in a sense. This results a much more welcoming environment for the sperm cells, especially during ovulation.

Helper T Cells are the cells in the immune system that attack the invaders. Each T cell is programmed to attack a certain type of invader. When couples trying to have a baby have more sex, the woman’s helper T cells become more diverse. So when the woman is more sexually active, there are more helper T cells that allow the intrusion of sperm during ovulation, and more that deny sperm intrusion during other periods in her cycle.

    This research is really fascinating! It’s amazing how so many aspects of health are so closely intertwined. I’ve heard that sex can boost your immune system, but it’s interesting to think that your immune system can work against the goals of that very activity as well.
