Hi and thanks for the query, Infertility requires a detailed clinical assessment of not only the female, but the partner. TB however could be a cause of infertility, but actually contributes a very small percentage to that. Tests evaluating infectious, hormonal, inflammatory, anatomic causes should be evaluated. The male factor i infertility contributes to over 1/3 of these. The sperm count and other parameters in the make also need a critical evaluation. I suggest you book an appointment with the infertility specialist, preferably with your partner for a critical planning and scheduling of the evaluation and management scheme. Excessive weight could play a very mild role in contributing to infertility, very very mild, but controlling your weight is a good aspect of health care to protect you from other metabolic diseases. Thanks and hope this helps, Luchuo, MD.
