As the saying goes, there are specialties in the field. Over the past decade, I have done some theoretical and practical research in chronic pelvic inflammatory disease and in the treatment of this platform of diseases caused by chronic pelvic inflammatory disease, and I have written a large number of scientific articles and also published some case reports in introducing my innovation in the treatment of chronic pelvic inflammatory disease, i.e. pelvic double-combination massage, referred to as pelvic local kneading. As a result, some of the patients who came to the clinic mainly because of chronic pelvic inflammatory disease and infertility were more often treated, and some of these patients showed delayed menstruation, and once the sex hormone six was checked, it was found that one of the ovarian functions was reduced, such as luteinizing hormone exceeding the normal range and reaching menopausal levels, while follicle stimulating hormone was in the normal range. Undergraduate or master’s obstetrics and gynecology textbooks only describe premature ovarian failure in women of reproductive age less than 40 years old, while there is little mention of ovarian hypofunction in reproductive age, and treatment is lacking. Some experienced gynecologists, after seeing reports of ovarian hypofunction, advise their patients to get pregnant as soon as possible, lacking targeted etiologic treatment (there is no corresponding chapter in textbooks), while inexperienced physicians simply promote menstruation or even use endocrine cycle therapy to artificially regulate menstruation, which are only symptomatic treatments and do not address the underlying causes of ovarian hypofunction. Gynecologists rarely think about whether menstrual disorders are associated with ovarian hypofunction because it is not in the textbooks, and even if they do, they are at their wits’ end when it comes to treating the causes of hypofunction. I have already written articles about the common causes and treatment principles of hypovarianism on this website, including reports on case treatment, for those interested to browse. Today, I would like to emphasize here to remind all patients that when your menstrual period is delayed for unknown reasons, please consult a doctor promptly to check the sex hormone six to determine if the ovarian function is normal. If you have ovarian hypofunction as described in this article, please seek treatment for the cause of the problem, rather than just using the so-called menstrual regulation including endocrine cycle therapy, remember, so as not to delay the disease, once the ovarian hypofunction gradually evolves into premature ovarian failure, you will lose the time to treat and regret too late. If premature ovarian failure occurs at the age of 30, it means that your female function is aging 20 years earlier. Personally, I think that many of the textbooks on menstrual disorders should be revised, otherwise not only will they be misleading, but they will also delay the treatment of the patient’s condition. Remember, once unexplained delay in menstruation occurs for several months in a row, it is necessary to determine whether ovarian function is diminished, and if it is diminished, timely and effective causal treatment is needed, otherwise it may cause irreversible results of premature ovarian failure. A gynecologist who does not look at the results of sex hormone six is a quack; a gynecologist who does not perform sex hormone six tests on patients with unexplained menstrual irregularities is an irresponsible gynecologist; a gynecologist who prescribes medication to promote or regulate menstruation without endocrine tests is an irresponsible quack, unless the patient volunteers.
