Most patients diagnosed with “premature ovarian failure” are unable to accept this fact, and many of them ask, “Why are my ovaries aging when I am only in my 30s? Did I do something wrong in my life?”. Many people ask, “Why are my ovaries aging in my 30s? The causes of premature ovarian failure are not yet clear, but there are many known factors such as genetics and immunity, which will be listed below. Genetic factors: Through careful analysis of family history, about 10% of patients with premature ovarian failure have a family history. Genetic factors are divided into: ① X chromosome deletion. The X chromosome deletion is usually caused by an error in the differentiation of germ cells. (ii) Genetic mutations. There have been further breakthroughs in the study of genetic predisposition to premature ovarian failure, and experts have identified a recessive gene, the mutated HFM1 gene. This means that if a father and mother each carry a mutated HFM1 gene, there is a 1 in 4 chance that their daughter will develop premature ovarian failure. This finding may in the future help people with a family history of the disease to anticipate the disease and get pregnant early to avoid regret; immune factors: about 20% of patients with premature ovarian failure. Anti-ovarian antibodies (which affect the development and function of the ovaries and follicles, leading to premature ovarian failure) can be detected in the blood of these patients, who often have a combination of other autoimmune diseases such as lupus erythematosus and rheumatoid arthritis. Idiopathic premature ovarian failure: This is the most common type of premature ovarian failure in clinical practice. Patients with normal chromosomes usually have no autoimmune antibodies and no clear cause can be found. Medical factors: These include surgery, radiotherapy and chemotherapy of the reproductive system. However, after the chemotherapy drugs are discontinued, the ovaries can return to normal function in 65% to 70% of patients. Other factors: such as infection with certain pathogenic bacteria, which invade the ovaries and cause inflammation and eventually develop into premature ovarian failure. Environmental and psychological factors, work stress, smoking, etc. may also trigger premature ovarian failure. In short, the cause of premature ovarian failure is difficult to determine, and it is not helpful for patients to dwell on it too much. The best choice is to actively treat the problem, maintain an optimistic attitude and improve your quality of life. You may ask, “Can I recover my ovarian function after treatment? Here’s an article with a detailed look at it.
