Tuberculosis of the female reproductive system occurs preferably in the fallopian tubes, endometrium and ovaries. 1. Tubal tuberculosis. It is the most common in clinic, accounting for more than 90% of female genital tuberculosis. The fallopian tubes are mostly thickened and enlarged, and the fallopian tubes with tuberculosis are often widely adhered to the neighboring organs, such as ovary and uterus. 2. Endometrial tuberculosis. Most of them are spread from tubal tuberculosis, and the endometrium will be damaged to different degrees and form scar tissue, which will make the uterine cavity adherent and deformed. 3. Ovarian tuberculosis. It is also mostly spread from tubal tuberculosis, and nodules and caseous necrotic abscesses may be formed in the deep part of the ovary.
