Hematometra can be caused by various factors, including:
1. Congenital anomalies: Structural abnormalities such as an imperforate hymen or vaginal septum can lead to hematometra. 2. Acquired obstructions: Conditions such as cervical stenosis, intrauterine adhesions (Asherman's syndrome), or uterine fibroids can obstruct menstrual flow. 3. Post-surgical complications: Procedures like endometrial ablation or cervical surgery can sometimes result in hematometra. 4. Infections: Severe pelvic infections may lead to scarring and obstruction.
