Often female patients cry to us through various ways, because they can not bear children and abandoned by their husbands; because they can not bear children and ashamed of their families; because they can not bear children and have no family status ……. In either case, once a woman is infertile, she will bring endless troubles and regrets to her family and herself. Watching them run around because of infertility, watching them emaciated and psychologically exhausted because of infertility, and listening to their helpless cries, as a gynecologist, I feel sympathetic and at the same time heartbroken – most of these things can be avoided! Everything has a cause and effect, so let’s see what are the previous causes of today’s results. 1, excessive scraping and emergency contraceptive pills Abortion is a remedial method used after the failure of contraception, is a minor outpatient surgery. Many women think this is nothing, and easily go for an abortion after an unplanned pregnancy. However, all surgeries have risks and abortion is no exception. With the introduction of ultra-guided visual abortion and painless abortion, the number of infertility patients due to abortion is increasing day by day. The endometrium consists of a mucous membrane layer and a basal layer. Once scraping too much damage to the basal layer of the endometrium, it is likely to cause low menstrual flow, amenorrhea, habitual abortion and even infertility; secondly, some young girls, pre-marital pregnancy due to economic limitations and psychological tension do not want to be known to other people, and more to the illegal black clinics for medical treatment. The small clinic is often due to hygiene conditions do not have, sterilization is not strict, the operation may be combined with the uterine cavity infection, the emergence of uterine adhesions and so on. Therefore, female friends must take abortion surgery seriously, especially the first pregnancy. One scraping may regret for the rest of your life! In addition, the use of inappropriate contraceptive measures is also a cause of infertility. Contraceptive measures at present mainly include oral contraceptive pills, condoms, contraceptive rings, intrauterine placement of birth control rings, buried wires, tubal ligation surgery and so on. Depending on the patient’s situation, the appropriate contraceptive measures will be used. Contraceptive pills are divided into: emergency contraceptive pills, short-acting contraceptive pills, long-acting contraceptive pills and so on. The main ingredient of emergency contraceptive pill is a large amount of progesterone, and the amount of hormone ingested in one use is comparable to that in 8 days of regular short-acting oral contraceptive pills. Large doses of foreign hormones can easily cause endocrine disruption and menstrual cycle changes in women. It should not be taken regularly. General contraceptives do not affect women’s fertility, but women who are over 35 years old, have low menstrual flow and have a history of smoking, after taking emergency contraceptive pills for a long period of time or many times, there will be a further decrease in menstrual flow, or even premature ovarian failure, thus affecting women’s fertility. 2, too old for childbearing China’s family planning policy stipulates that the standard of late marriage for women is 23 years old, and the standard of late childbearing is 24 years old. However, the actual situation now is that the pressure of study and work is too great, when graduating from university, graduate school or even doctoral degree, the age of the girl is far from twenty-three or twenty-four, and most of them are already twenty-eight or twenty-nine, or even thirty years old when getting married. By the time they give birth they are mostly over thirty. There are also some women who postpone childbearing indefinitely for the sake of their careers. However, women’s ovarian function decreases with age. The development of human follicles begins during the embryonic period. The number of follicles in the ovary is limited. The reserve capacity of the ovaries decreases with age. From the age of 35, follicular depletion shows an accelerated process, so that by the age of 38 there are only 25,000 follicles, 15,000 at the age of 40, 5,000 at the age of 45, and by the age of 50 only a few hundred remain. The decrease in follicle number is accompanied by a decline in egg quality. Therefore, although a small number of follicles remain in older women that are sufficient to maintain menstruation, the decline in egg quality reduces the chances of fertilization, implantation, and early embryonic development, resulting in a significant increase in the chances of clinical infertility and miscarriage. The growth of human growth and old age has been like the four seasons of plowing, to comply with the natural seasons of life, the blossom should be blossomed, the results should be timely results, miss the season, you have to double the efforts, and even leave lifelong regrets. 3, the adverse effects of the treatment of related diseases Modern medicine can be said to be developed. But the sub-specialties are too fine, the lack of effective communication between specialties and specialists, the treatment of this disease often ignore the other disease, will also bring some regret to the patient. Since Stein and Leventhal reported the disease of polycystic ovary syndrome (PCOS) in 1935, PCOS has become more and more recognized, and the clinical incidence rate is high. Numerous treatment options have been proposed for this popular disease, ovarian perforation surgery with ovarian wedge resection being one of them. In the short term these surgeries restore the patient’s ovulation, but in the long term artificially reduce the patient’s ovarian reserve, and some patients even develop premature ovarian failure as a result, leading to lifelong regrets. Ovarian tumors, uterine fibroids, endometriosis and other diseases modern medicine are keen to solve the problem of surgery, however, in the pelvic surgery, on the one hand, direct damage to the ovarian cortex to reduce the number of basal follicles, on the other hand, affecting the blood supply to the ovaries, indirectly reducing the ovarian reserve, or affecting the uterus endometrium to make the formation of scars or depressions, which affects embryo implantation, resulting in infertility or habitual miscarriage. Celiac disease is a common gynecological disease, and there are many treatment methods. Surgical treatment is currently popular “LEEP knife”, the indications for LEEP knife surgery was originally CINII (cervical pre-cancerous lesions) or more lesions can be used, but now its indications have a tendency to expand, but all serious cervical erosion, most of the use of this method of treatment. However, the main problem with LEEP knife treatment is that too much tissue is removed. The length of the cervix has an impact on fertility. A cervix that is too long or too short reduces the chances of pregnancy and can even lead to infertility. In addition, the treatment of internal diseases, the toxic side effects of some drugs can also lead to the loss of ovarian function, such as the treatment of systemic lupus erythematosus and rheumatism for long-term use of the tretinoin, can lead to the decline of ovarian function, which will lead to the occurrence of premature ovarian failure, resulting in amenorrhea and the occurrence of infertility. Therefore, before pelvic surgery, including cervical surgery, both patients and doctors should measure the pros and cons of surgery and timing, to avoid causing the cure of this disease, bring his disease. 4, excessive obesity and blind weight loss Whether it is “fat ring” (Yang Yuhuan) or “thin swallow” (Zhao Feiyan) have a common characteristic “infertility”, that is to say, excessive obesity and excessive thinness may have infertility. That is to say, excessive obesity and excessive thinness may have infertility. Modern medicine has proved that when the ratio of fat and muscle is out of proportion, women’s endocrine disorders, menstrual irregularities, infertility, miscarriage and other diseases. Some data show that 6% of infertility patients are underweight. Obesity leads to infertility was recognized in ancient times. Such as “Fu Qingzhu women’s science, seed chapter”: women have obesity, and want to paste Liang thick taste, so that phlegm and dampness, flow injection of the ramus cell veins; or because of the body fat overabundance, congestion of the cell veins and the uterus and lead to infertility. Modern medicine has also confirmed that obese patients due to excessive estrogen storage or due to aromatase deficiency androgen intermediary metabolite accumulation, which affects the hypothalamus – pituitary – normal function of the ovarian axis, thus causing ovulation disorders, anovulation, ovulation sporadic etc. In addition, it has also been found that obese people due to endometrial abnormalities (atrophy or excessive thickening) and cause infertility. Therefore, proper diet control, daily aerobic exercise, maintain a healthy body, fertility has great help. 5, bad habits and occupational environment With the improvement of the social status of modern women, the pressure of life and work is also increasing, more and more women’s fertility is invariably affected by some of the modern living habits and occupational environment. Alcohol and coffee. Drinking alcohol is not only necessary for entertaining guests, but also a way of expression when people are happy or depressed. However, alcohol has a significant impact on the female reproductive system. Alcohol can not only make the chromosome structure and number of reproductive cells change, affecting eugenics, but also jeopardize the function of the female reproductive system, leading to endocrine disorders, hindering the development and maturation of the female egg, leading to ovarian ovulation, thus leading to female infertility. Fertility is significantly reduced in women who regularly drink alcohol, especially alcoholism. Sipping and drinking coffee has become a fashionable lifestyle, pursued by many young people. However, studies have shown that women who consume 300 mg or more of caffeine a day take longer to conceive than those who consume less or no caffeine, and are prone to miscarriage after pregnancy. Even drinking only two cups of coffee a day reduces fertility by 50 percent. Cola drinks have the same effect, as colas also contain high levels of caffeine. Smoking. Some young women smoke as a fashionable form of behavior, but they do not know that the nicotine and nicotine contained in cigarettes can cause vascular lesions throughout the body. Once the blood vessels of the uterus are thus affected, miscarriage is likely to occur in early pregnancy and hyperemesis gravidarum may occur in mid-pregnancy. Long-term smoking also harms the body’s entire hormonal system, affecting ovarian function and leading to endocrine disorders causing infertility. Staying up late. Due to excessive work pressure and lifestyle changes, the traditional habits of working at sunrise and resting at sunset have long been discarded and replaced by staying up late. Regularly stay up late, not only reduce the body’s immune function, but also affect the secretion of female hormones and the quality of eggs, causing menstrual disorders, premature ovarian failure, which leads to the occurrence of infertility. Mental tension and excessive pressure, women of childbearing age are in a state of long-term mental tension, which can easily lead to female reproductive axis, and hypothalamus-pituitary-ovary axis dysfunction, endocrine disorders, resulting in menstrual disorders, affecting fertility. Nowadays, the intensification of competition for jobs is that many women in the workplace are under increased pressure, and being in a state of worry, depression or fear for a long time is likely to reduce women’s fertility. Undesirable occupational environment. Modern people who live and work in frequent contact with chemicals, lead, anesthetics or X-rays and other chemical pollution, physical radiation, as well as dietary contamination, the human reproductive function will suffer some damage. Occupations related to this are mainly paint-related production and home furniture sales, operating room medical staff, beauty salon, laboratory staff, pesticide production and sales staff and other jobs. Or working in a freshly renovated environment. When women’s reproductive health is damaged, in addition to menstrual abnormalities, early menopause, more often manifested in infertility, spontaneous abortion, hypertension syndrome during pregnancy, low birth weight babies, deformed babies, and even the emergence of fetal death and other diseases. Women’s health care should first start with protecting reproductive health. Flowering in season and fruiting at the right time require careful care and maintenance in general. The same applies to women’s fertility. In a woman’s life, there is not only the inevitable process of being a daughter, there is also the contingent stage of motherhood, the lack of the latter stage of a woman’s life is bound to have many regrets. Avoiding the influence of adverse factors, protecting women’s fertility, and being a complete woman require the joint efforts of doctors and patients!
