[/INST] Hi, Thanks for writing to Chat Doctor. You and your husband are diagnosed as normal couples. There are still many problems which can cause infertility.  Like problem in fertilization of egg or problem in implantation.  Since you are trying from 5 years I would suggest you to go for IVF I.e. in vitro fertilisation.  Here the problem of fertilization is solved as in this procedure they fertilize egg outside, and then they place them into uterus. They place 3 to 4 fertilized egg into uterus. So chances of conceiving increase. This will help you. You can discuss with your doctor. Hope I have been helpful. Regards Chat Doctor.  </s>
