What are the causes of premature ovarian failure?

Premature ovarian failure may be caused by genetic factors, autoimmune diseases, iatrogenic injuries, viral infections, environmental toxins and other factors. Premature ovarian failure refers to the decline of ovarian function in women before the age of 40, which is manifested by symptoms such as amenorrhea, infertility, and decreased estrogen levels.

1. Genetic factors

Some patients with premature ovarian failure have a family genetic tendency, which may be related to X chromosome abnormalities or specific gene mutations. Such patients may be accompanied by primary amenorrhea or premature menopause, and karyotype analysis is recommended. For premature ovarian failure caused by genetic factors, symptoms can be improved through hormone replacement therapy. Commonly used drugs include estradiol valerate tablets, progesterone capsules, etc.

2. Autoimmune diseases

Autoimmune oophoritis is a common cause of premature ovarian failure. Patients may produce anti-ovarian antibodies that destroy the follicle structure. Such patients often suffer from immune diseases such as thyroid disease and systemic lupus erythematosus. Treatment requires controlling the primary immune disease. If necessary, use immunosuppressants such as prednisone tablets and estradiol gel for hormone supplementation.

3. Iatrogenic injury

Pelvic radiation therapy, ovarian surgery, or chemotherapy drugs may directly damage ovarian tissue. Young women undergoing cancer treatment may develop treatment-related premature ovarian failure, manifested by elevated levels of follicle-stimulating hormone. For such patients, cryopreservation of ovarian tissue can be considered before treatment, and long-term use of conjugated estrogen tablets is required to maintain physiological functions after the disease occurs.

4. Viral infection

Infections such as mumps virus and cytomegalovirus may cause oophoritis, resulting in reduced follicular reserve. Such patients often have a history of acute fever and subsequent menstrual disorders. Premature ovarian failure after viral infection requires early intervention. Compound hormone preparations such as Climen can be used, and calcium supplements can be used to prevent osteoporosis.

5. Environmental toxins

Long-term exposure to environmental pollutants such as pesticides and heavy metals may interfere with ovarian function. The polycyclic aromatic hydrocarbons in tobacco can accelerate follicle depletion, which manifests as shortening of the menstrual cycle until amenorrhea. Such patients should stay away from polluted environments, regulate their menstrual cycles with dydrogesterone tablets, and increase their intake of phytoestrogens such as soy products.

Patients with premature ovarian failure should maintain a balanced diet, appropriately increase their intake of high-quality protein and calcium, and engage in regular aerobic exercise. Avoid bad habits such as smoking and drinking, and control caffeine intake. Regularly monitor bone density and blood lipid levels, and adjust the hormone replacement treatment plan under the guidance of a doctor. When you experience menopausal symptoms such as hot flashes and night sweats, you can try acupuncture. Maintaining an optimistic attitude can help improve symptoms.
