question: my husband and i have been taking infertility  treatment for almost 6 years for now. i am 34 years old. But there has not even been a symptom even once. i have undergone 9 IUIs. as far as our health is concerned the doctors say that everything is good. the doctors say that it is an unexplained case.the years are passing by and we are worried about the age factor. we have seen a few doctors in and around coimbatore. we now prefer to go for test tube baby. is it possible for us?
