For most couples, having a big family is one of the most fulfilling things that can happen to them. People who have huge families never have to ask what is unexplained infertility. These people love the idea of going home to happy and smiling kids who shower you with hugs and kisses in the evenings.
Medical fraternity uses the phrase “unexplained infertility” because they can’t figure out the real cause of infertility with their regular tests. Just because doctors say it can’t be explained, you should not assume that it can’t be explained. Doctors rely upon certain diagnostic tests to fix the cause of infertility. They can’t perceive beyond that.
