1, age is the biggest scourge of fertility Age growth has a great impact on female fertility, in terms of female physiological rules, the strongest fertility in 20-24 years old, 30 years old after the slow decline, 35 years old after the rapid decline, 35 years old is half of 25 years old, 40 years old is half of 35 years old. 44 years old after about 87% of women lost the ability to conceive. 2, excessive obesity is not conducive to pregnancy obesity will damage female endocrine, will also prevent ovulation, but also trigger a variety of health problems, such as: high blood pressure, diabetes, heart disease. These diseases may also cause women to be infertile and can cause some complications in the process of pregnancy. Morbidly obese women will also have a lower success rate in trying fertility treatments. 3, blind weight loss can also lead to infertility Blind excessive weight loss may lead to endocrine disruption, menstrual cycle disorders, ovulation stop. The nutritional imbalance and severe deficiency of micronutrients brought about by excessive dieting can also affect fertility. Especially for women over the age of 30, fertility itself has declined, more cautious weight loss. 4, mental tension and stress affect fertility Women of childbearing age, if the environment changes, emotional fluctuations, long-term under great stress, it is easy to endocrine disruption, menstruation began to disorder or even become non-menstrual, do not ovulate, in this case, of course, it is not easy to get pregnant. The increased competition in employment makes many women in the workplace more stressful, and the long term mental state of worry, depression or fear will affect women’s pregnancy. 5, inflammation of reproductive organs affect fertility When suffering from vaginitis, the vaginal pH changes and white blood cells increase, which will prevent the viability of sperm and reduce mobility, and the local internal environment caused by inflammation of the cervix is changed, which is not conducive to the passage of sperm through the cervix, thus leading to infertility. If the pelvic infection is not treated promptly and thoroughly, especially tuberculosis or gonorrhea infection, even if it heals, it can cause adhesion, distortion and narrowing of the fallopian tubes, leading to infertility or ectopic pregnancy. 6, poor sexual habits endanger fertility Some young women have unhygienic sex, sexual promiscuity, infected with STDs, often in the incubation period, a moment can not see the impact, but unknowingly triggered pelvic inflammatory disease, resulting in infertility. The menstrual period intercourse easily allows bacteria and blood to enter the pelvic cavity through the loosened official neck opening, triggering infection. More seriously, if the refluxed menstrual blood remains in the pelvic cavity, it can cause endometriosis. Both are fertility-destroying killers. 7, harmful chemicals affect pregnancy Many chemicals contain toxins that can destroy egg cells and are also likely to cause endocrine disruption. Some waterproof clothing, 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. 8, alcohol, coffee harm fertility often drink alcohol, especially alcoholic women, fertility will be significantly weakened. Because alcohol will prevent the absorption of nutrients, just one glass of red wine may reduce the body’s zinc content, and zinc is an essential factor in fertility. Caffeine – even just two cups of coffee a day can reduce fertility to a degree of 50 percent. Coke drinks have the same effect, because cola also contains a lot of caffeine. 9. Abortion is the second leading cause of female infertility Doctors have found that the number of abortions is directly proportional to the chances of infertility. Multiple abortions are likely to lead to pelvic adnexitis, blockage of the fallopian tubes after inflammation and infertility. The highly active endometrial debris from abortion can easily be transferred to the pelvic cavity and implanted to form endometriosis leading to infertility. Moreover, repeated abortions also make the endometrium very thin, so that if you get pregnant later, the embryo is like a seedling in the sand, which does not get enough nutrients and is easily stunted and aborts on its own.
