The tubercular infection
which you mentioned is a type of infection and can be treated with the use of antitubercular drug completly. As you told that you already have 9 months treatment and I hope this is cured now.
Now lung tuberculosis
once cured has not effect on pregnancy
and I think this is not the main reason for you not able to conceive. Lung tubeculosis is not going to do any harm to the organs related with conceiving. I would suggest you to consult some infertility
expert for this problem and in the mean time try to improve you general health condition with proper diet and life style and try to avoid anxiety and depression
as this is very important for sexual health.
Thanks and take care.
