Women can take precautions by acquiring the necessary scientific knowledge of reproductive medicine. At the same time, women who experience these early warnings should also be aware that this is likely to be the “killer” of infertility. Here are six warning signs of female infertility. Alert 1: Endometriosis When a woman finds that she has abnormal bleeding, dysmenorrhea, cyclic rectal and anal cramps and other clinical manifestations, accompanied by low back pain and pain during sexual intercourse, she should consider that she may be suffering from endometriosis. This disease can cause infertility in 75% of women and should not be taken lightly. Alert 2: Endometrial tuberculosis The primary focus of the disease is tuberculosis of the lungs, followed by peritoneal tuberculosis, which spreads through the bloodstream, first invading the fallopian tubes and then spreading to the endometrium, leading to infertility. Severe cases of this disease have obvious symptoms, and in addition to genital lesions, they are accompanied by systemic symptoms, which women should actively combat. Considering the factor of pregnancy, it is recommended that women with this disease use traditional Chinese medicine to minimize the side effects. Alert 3: History of appendicitis Many people do not know that appendicitis is not only prone to cause ectopic pregnancy in women in the future, but also due to the perforation of appendicitis may also cause tubal infarction, which may lead to female infertility. Therefore, this problem should be taken seriously. Alert 4: Repeated abortions Repeated abortions may lead to excessive scraping of the uterus, involving part of the basal layer of the uterine membrane, making it difficult for a fertilized egg to attach to the uterus. Secondly, post-abortion is prone to infection, which can cause gynecological inflammation, which in turn affects sperm motility and survival time. These can make the fertilization rate lower. For example, inflammation of the fallopian tube may affect the combination of sperm and egg. Alert 5: Abnormal obesity Human weight has a great relationship with the body’s endocrine function. If a woman’s endocrine function is disturbed, it will make the muscle body tend to be obese, affecting ovulation and leading to infertility. This kind of infertility, in Chinese medicine is called phlegm-dampness blockage and cause infertility. Therefore, women who are infertile for this reason can only normalize their menstruation and conceive if they control their weight and stop gaining it. Regular menstruation is an important indicator of the maturity of female reproductive function and a barometer of female reproductive endocrine health. Menstruation is the periodic shedding and bleeding of the uterine lining that occurs along with the cyclic changes of the ovaries. It is cyclic and self-limiting, and if there is more than one vaginal bleed or a disruption of the cycle, it is considered abnormal and requires prompt medical attention. The menstrual cycle is calculated as the number of days between the first day of the last menstrual period and the first day of the next menstrual period. A normal menstrual cycle lasts for 21-35 days, with an average of 28 days, and the normal menstrual period lasts for 2-7 days, and the amount of menstrual flow ranges from 30-50 ml, while a flow of more than 80 ml is known as excessive menstruation. Menstrual disorders include abnormal cycles and abnormal amounts. Cycle less than 21 days is called frequent menstruation, while more than 35 days is called scanty menstruation, or even completely irregular “chaos”, these three cases are different degrees of follicular development abnormalities and or ovulation disorders, there is no normal “seed” (high-quality mature eggs) production. Without the production of normal “seeds” (good quality mature eggs), infertility will inevitably result. It has been reported that about 75% of patients with irregular menstruation are diagnosed with PCOS (Polycystic Ovary Syndrome). On the other hand, abnormal menstrual flow can be characterized by decreased, excessive or heavy menstrual flow. Decreased menstrual flow may be associated with thin endometrium, uterine adhesions, or endocrine abnormalities such as hypothyroidism or hyperprolactinemia; excessive menstrual flow may be associated with endometrial thickening, uterine fibroids, adenomyosis, or systemic diseases such as hematological disorders; and heavy menstrual flow may be associated with endometrial polyps, endometrial hyperplasia, endometrial malignant diseases such as endometrial carcinoma, and, in rare cases, with cervical lesions that result in endometriosis. In a few cases, it is also related to abnormal bleeding caused by cervical lesions, however, the bleeding caused by cervical lesions is often contact bleeding (after coitus or after examination). In addition, menstrual disorders can be associated with metabolic abnormalities such as obesity, which can return to normal when weight is reduced. Therefore, when the occurrence of menstrual disorders should be timely medical treatment, it not only affects fertility, but also closely related to the health of women throughout their lives. Warm reminder: the prevention of infertility should start from young girls. If a young girl is cold during menstruation, she will experience cold and stagnation of qi, stagnation of qi and stagnation of blood, which will lead to infertility. Young girls in the menstrual period, such as do not pay attention to hygiene, but also very easy to suffer from a variety of women’s diseases, these diseases will prevent pregnancy after marriage. Generally speaking, young girls suffer from menstrual disorders cause is relatively simple, treatment is relatively easy, Chinese medicine can solve the problem. However, if the problem is delayed for a long time, it will be more difficult to treat after marriage. If there is no natural pregnancy after one year without contraception, then you can start checking. However, people with primary amenorrhea or long-term secondary amenorrhea should be seen earlier. Patients should undergo a thorough examination to achieve one or more correct diagnoses. If a patient has tubal obstruction and is also not ovulating. Then there is no point in treating ovulation until it has been established that the tubes are open.
