Hello and welcome to HCM, Thank you for your query. I understand your anxiety, and shall try to explain things in a simple and more detailed way. Tuberculosis in males is caused as tuberculosis spread to the genitals and causes tuberculosis epidydimo-orchitis (which results in obstruction of the passage through which sperms empty into the semen). This results in azoospermia. Most male patients are diagnosed in the late stage as diagnosis is not easy. If an early diagnosis is there is a chance we could detect the disease before it causes complete obstruction of those passages. This can be treated with the immediate initiation of anti-tubercular therapy (to prevent progression) of the disease and then correction (removal of obstruction through surgery). If detected in the late stages, it solely depends on location of the obstruction and feasibility of reconstruction (surgical). Please continue the AKT4 medications for now, and complete the course. The next step in our course would be to find the location and the amount of obstruction. Depending on this information we can decide what could be done next, and only then will I be able to honestly answer your question on whether to wait for the completion of treatment or go ahead with IUI. I hope I have succeeded in answering your questions, you could write back to me anytime for further clarifications. Best wishes.
