Thanks for your query.
I read your query and understand your concerns.
Following is my reply:
Failure of fertilization is not due to tuberculosis
There might be some problem with egg, sperms or the temperature of incubator in IVF laboratory.
I suggest you change over to different IVF centre in your next cycle of treatment. If same thing repeats, you may have to consider donor semen / donor eggs.
I hope I answered your query. I will be available for any follow up queries you have.
