[/INST] Hey thanks for your faith in the Chat Doctor.I have gone through your question and understood your problem. Yes TB causes blockage of Fallopian tubes. If your gynecologist diagnoses you as having genital TB based on these unreliable tests, then please do NOT start anti-TB medicines. Please insist on getting a second opinion from a physician, preferably once who is a TB specialist. Wait till culture reports. Hope I have answered your query. If you like my answers and wish me to answer in the future, bring it to my attention </s>
