There are times when we give patients the results of in vitro fertilization, we tell them that the test is positive, but that it is not good news, and that the chances that it involves into an ongoing pregnancy are slim. It is a very difficult situation, emotionally, since it is very hard for patients to understand what has happened. If it really is positive. Then why isn’t that good news? If it’s not good news, then why do I still have to take medication?
