1, don’t let yourself be too fat to affect ovulation Women’s normal ovulation requires the normal operation of the hypothalamic-pituitary-ovarian axis. The hypothalamus gives orders to the pituitary gland to secrete gonadotropin, and the ovaries receive the instructions of gonadotropin to secrete estrogen and progesterone to promote the development and maturation of follicles and then ovulation. Excessive obesity can affect the hormone secretion of women, resulting in abnormal menstrual cycles and thus affecting the normal ovulation function. At the same time, excessive obesity can also cause various health problems, such as: high blood pressure, diabetes, heart disease, etc. These diseases may also cause infertility in women, and can cause some complications in the process of pregnancy, so that the pregnant mother-to-be more for the risk. Dear fellow women, if you happen to be uncontrolled food, and do not exercise, weight seriously more than the standard weight, then we should be alert. The most important thing is that you can get the most out of your life. The older a woman is, the fewer eggs she has left in her body for normal fertility. At the same time, the uterine lining may become thinner and less suitable for fertilized eggs to bed; vaginal secretions may become less fluid and less accessible to sperm. The rate of fetal malformations is also higher for senior pregnant women over 35 years old, and can lead to complications such as high blood pressure, diabetes, heart disease, kidney disease and various pregnancy complications and aggravation, resulting in intrauterine growth and developmental delay of the fetus. 3, blind weight loss endocrine disorders Due to changes in the concept of aesthetics, most girls are now “bony” for beauty, not knowing that too thin women are also prone to infertility. The general height of 1.6 meters of mature women, the best weight more than 50 kg, in order to constantly ovulate. This is because when a mommy-to-be does not have enough fat in her body, her brain will gradually produce an endocrine substance called “lipo-leptin”, which makes women’s reproductive function diminish, and this adverse effect is irreversible. On the other hand, weight loss through a restricted diet is also prone to nutritional imbalances, and micronutrient deficiencies can also affect fertility. Therefore, women who love beauty should not lose weight blindly to avoid endocrine disruption, menstrual cycle disorders and ovulation cessation. In order to give birth to a healthy baby, it is best to maintain a healthy and proportionate body, do not pursue bone and deliberately lose weight. 4. Toxic chemicals harm egg cells For women who work in certain special positions (such as in biochemical laboratories), they must leave their jobs at least six months in advance if they are preparing to get pregnant. This is because the toxins in many chemicals can destroy the egg cells and are also likely to cause endocrine disruption. Some waterproof clothing on the market, insecticides, food packaging, interior decorations, Teflon non-stick coatings and other goods containing perfluorinated chemicals, not only to the human liver, immune system, development and reproductive organs bring toxicity, resulting in infertility, but also affect fetal development. 5. Beware of gynecological inflammation that hinders sperm viability Throughout her life, a woman should focus on vaginal hygiene checks. If the vagina speaks, the pH of the vagina changes and the white blood cells increase, these will prevent the sperm from being viable and the mobility decreases, and the local internal environment caused by the inflammation of the cervix changes, which is not conducive to the passage of sperm through the cervical canal, thus leading to infertility. If the pelvic infection is not treated timely and thoroughly, especially tuberculosis or gonorrhea infection, even if it heals, it can cause adhesions, distortions and narrowing of the fallopian tubes, which can lead to infertility or ectopic pregnancy. 6, often drink coffee is not conducive to fetal growth Coffee is not only fragrant and good taste, but also can refresh and replenish energy. Therefore, in the workplace women in a big hand sought after. However, the caffeine contained in coffee is not so simple. Caffeine can easily cause metabolic disorders in the placenta, which is not conducive to the healthy growth of the fetus. Also, instant coffee contains a lot of sugar, which is not good for health. If you are trying to get pregnant, for safety’s sake, it is wise to say goodbye to coffee until the baby is born. Some women are prone to infertility due to a lack of medical knowledge, so they always respond to their husbands’ requests for pleasure, even during their periods. Women’s physique is poorer during menstruation, and are susceptible to bacterial infections, so it is not possible to have intercourse during menstruation. If you have intercourse during this period, it can lead to a series of hazards. Hazard one: intercourse during menstruation, due to the contraction of the uterus during the sexual impulse, can also squeeze the endometrial debris into the pelvis, causing endometriosis and leading to infertility. Hazard 2: During menstruation, the endometrial lining is exfoliated and the alkaline menstrual blood neutralizes the acidic environment of the vagina, weakening the natural barrier function. If you do not pay attention to menstrual hygiene, or even have intercourse during menstruation, you will bring bacteria into the reproductive tract, which will easily cause infection and lead to female infertility. Hazard three: menstrual intercourse, because the sperm in the endometrial breakage and the overflow of blood cells meet, and even into the blood, can induce the production of anti-sperm antibodies, leading to immune infertility, sterility. 8, frequent abortions beware of loss of fertility When some parents-to-be are not even ready, the baby has come unexpectedly. Many women mistake “painless abortion” as “harmless abortion” and decide to keep their babies at will. The number of abortions is directly proportional to the chance of infertility. Abortion can lead to pelvic adnexitis, blockage of the fallopian tubes after inflammation, and infertility. And most importantly, repeated abortions can make the lining of the uterus very thin, and when you want to get pregnant and have a baby, the embryo in your belly can be like a seedling in the sand, not getting enough nutrients and prone to stunting and aborting on its own.
