Most of us are goal oriented. As a result, any obstacle that interferes with us achieving an important result produces changes in our physiology that are referred to as “stress.” Sometimes stress can be a positive response. It can help us think creatively, remember details better and provide motivation to try harder. Unfortunately, the stress associated with trying to conceive is not helpful.
Whether trying to become pregnant naturally or with medical assistance; we work with our patients to help reduce the physiologic obstacles created by stress. One of the simplest ways to help reduce stress is to smile. Even when smiles are artificially induced; they can reduce the physiologic impact of stress. But we encourage people to go even further.
As a scientist and clinician, I love having data to further support recommendations. Research on how your body responds to laughter has shown improved immune function. In fact, that data focused in on a specific type of immune cell (NK cell) that we know impacts implantation and early pregnancy. But the best data comes from testing the hypothesis in real world situations like what has been done on patients going through IVF.
One well-designed interventional study followed 220 couples going through IVF. They had half of them randomly assigned to meet with a comedian around the time of their transfer to promote laughter. They found that the pregnancy rate in those exposed to laughter were almost double! Although this study has not (yet) been repeated; the results do make sense. We’ve all experienced serious situations where we have laughed—sometimes even apologizing for our laughter—only to feel better afterwards.
So as you proceed, consider the following advice: “Laugh often and smile loudly”
