I watched GMA (Good Morning America) yesterday morning. They had a short segment on infertility and stress. It was interesting, especially to someone with unexplained infertility. It basically said that the hypothalamus (sp?) plays a direct role in ovulation. Basically your hypothalamus keeps a running total of your day to day life and stress level. When you are under too much stress, the hypothalamus basically tells your body not to ovulate. I have always believed that your stress level in life plays a part in your entire well being, but it was interesting to know that for us with unexplained infertility, it may not be an actual medical condition that is keeping us from ovulating, it may just be our bodies way of telling us to slow down and destress ourselves.
