Welcome to HCM,
Unfortunately TB of Tubes causes structural damage to the tubes. Inspite of successful treatment for TB, structural damage does not revert back to normal. In majority of cases of TB of Tubes, uterus
also gets affected. In fact, the Doctor should have removed your tubes befoe your First IVF. Hysteroscopy
is a good diagnostic investigation, but again it has its limitations. Biopsy
also depends on the quality of sampling, and it can rule out active TB
, but the capacity to prepare a bed for fertilized ova to implant is another thing.
Male factor also has an important implication on success of fertility
. As the age increases, again the chances of Succecc of IVF reduces. Nevertheless, we should not lose hope.
You as a couple should talk to the Doctor, and discuss about other options also.
