Hello, I have gone through your query and here are your answers. 1. Tuberculosis of the pelvis is likely to affect the genital organs including the uterus. Since your fallopian tubes have been shown to be affected, it is possible that your endometrium also is affected. 2. As you are on ATT now, you should avoid pregnancy until the treatment is over. 3. Steroid treatment for NK cells is better avoided for the time as immunity is compromised with tuberculosis infection. Other modes of treatment may be considered if you are fit. 4. Taking all the above facts into consideration, I would ask you to think of IVF or surrogacy as natural conception chances are very low. Hope this helps.
