Infertility tends to be younger.
Couples seeking medical treatment in reproductive medicine clinics of major hospitals have the same purpose-giving birth to a baby; Symptoms are different, some are infertility, some are infertility.
People often confuse "infertility" with "infertility" In fact, the medical definitions of the two are different. Couples of childbearing age who live together after marriage, have no contraception, have normal sexual life, and the woman has not been pregnant for more than two years are called "infertility". "Infertility" refers to those couples of childbearing age who are pregnant after marriage and cohabitation, but fail to obtain live babies due to spontaneous abortion, premature delivery or stillbirth.
A set of figures is shocking: 20 years ago, the infertility rate of childbearing age population in China was only 3%, which was at a low level in the world. At present, there are/kloc-0 couples of childbearing age in this city, and the incidence of infertility in this city is increasing year by year, accounting for about 1 0%, which is close to the ratio of 15% to 20% in developed countries.
Several culprits leading to infertility
In addition, compared with thirty or forty years ago, the number of males per milliliter in China has dropped from about 654.38 billion to the current 20 million to 40 million; Moreover, the quality and activity of * * * are obviously reduced.
According to the Survey Report on Infertility Status in China released by the 2009 China Infertility Forum held at the end of August this year, among the infertile people in China, the age group from 25 to 30 is the largest, showing a trend of youthfulness. The Third Asia-Pacific Male Science Forum, which closed recently, warned that the infertility rate in China is rising, and the "infertility tide" has quietly landed.
Environmental pollution and stress are the main culprits.
What took away people's exuberant fertility in just 20 years? Experts pointed out that environmental pollution and work pressure are the main reasons for the rising incidence of infertility, especially for men.
Chen, president of the Beijing Sub-health Prevention and Control Association, said that in modern society, the pace of life is fast, the work pressure is high, and the pressure affects the mood, which in turn affects the endocrine, so that the quantity and quality of men are greatly reduced. At the same time, Chen pointed out that environmental pollution has a greater impact on male fertility than intense work pressure.
Jiang Yuwen, director of the Department of Traditional Chinese Medicine of the First Affiliated Hospital of Tsinghua University, also said that the decline of fertility of modern people is caused by comprehensive factors such as environmental factors, work pressure and living habits. The so-called environmental factors refer to food additives, pesticides, preservatives, detergents, flavors, paints, dyes, cosmetics and other substances. Most of them are fat-soluble, relatively stable in the environment and difficult to degrade. They can enter the human body through food, water or contact, play the role of estrogen, interfere with normal hormones in the body, cause reproductive dysfunction, and lead to the decline of pregnancy times, quality and penetration rate.
In addition, many people delay childbearing age, and the older they get, the lower their fertility will be. Jiang Yuwen pointed out that after the age of 30, the quantity and quality of * * * will decline, and the reproductive age of men should not exceed 35 at the latest.
Infertility favors "model workers"
Experts agree that the most popular infertility patients are "model workers". Model worker refers to the backbone of the company aged 25-40. This person is busy at work, under great pressure, easily nervous, and has many social activities at work. Long-term mental stress, rich nightlife, lack of sleep, frequent active or passive smoking and drinking. Are risk factors for infertility.
A couple found infertility, and the old concept always thought it was the woman's problem. In fact, male and female factors account for half of the causes of infertility. In addition, men are more likely than women to find the "source" of infertility. Experts say that infertility should first check the man's problems, and then check the woman if there is no problem.

Keep in mind the six elements and stay away from "being dink"
Some couples love freedom and the sweet "two-person world", so they voluntarily choose not to have children and become "double-income childless". However, some people are forced to become "Dink families" because they can't have children. If you don't want to be a "Dink", then you need to stay away from the following risk factors.
Don't smoke or drink.
In order to keep up with the trend, some men often drink at parties with classmates and friends, while others are often busy with entertainment and toasting because of work needs. As we all know, alcohol will obviously damage the quantity, activity, form and function of * *. Especially drunk, will make * * * quality decline. The damage caused by drunkenness once can't be recovered in a day or two. Experts believe that a man with a family planning plan can get his wife pregnant at least three months after being drunk.
Studies have also confirmed that the number of smokers is lower than that of non-smokers. Smoking not only affects the quantity, vitality and normal form of * * *, but also reduces the egg penetration rate of * * * *. Smoking can make adrenal medulla secrete more catecholamines, which can damage the epithelium of seminiferous tubules (seminiferous tubules are the place where * * *), and the number of * * * will naturally decrease.
Take less hot baths and saunas.
Sauna and hot bath are fashionable and healthy leisure ways, which can eliminate fatigue and restore vitality. However, it is very unfavorable for unmarried and childless men, because frequent sauna and hot bath can also cause infertility. The reason is that the temperature of testicles is generally 3-4 degrees lower than human body temperature to produce normal * * *, and * * * has strict requirements on temperature, which must be lower than body temperature to grow and develop, while the temperature of sauna and hot water bath is much higher than body temperature, which is not conducive to * * *.
Not only sauna and hot water bath can lead to infertility, but also other living habits, such as wearing jeans, tight-fitting, sedentary, long-distance cycling and so on, can affect fertility.
Stay away from lead pollution
When the intake of lead is greater than the discharge, the lead in the blood will increase, and when it accumulates to a certain amount, it will not only cause early lead poisoning, but also cause male infertility. A recent study in the United States shows that in the * * * with high lead content, the receptors used by the head of * * * to recognize and bind the sugar on the surface of the egg decrease, and the ability to penetrate the outer layer of the egg and bind the egg becomes worse. Self-destruction is more common before reaching the egg, which reduces the probability of pregnancy.
Experts pointed out that it is possible to prevent and reduce lead pollution. If you stay away from the lead industry pollution area, try to use and contact lead pollutants that may exist in daily life as little as possible. In addition, we often eat some foods that can discharge lead, such as milk, shrimp skin, tea, garlic, carrots, pumpkins, kelp and bean sprouts, fresh dates, oranges and so on.
Early treatment and prevention are the first priority.
Science has proved that many diseases that can lead to infertility will not develop into infertility if they can be found early and treated thoroughly.
For example, pelvic inflammatory disease, if it can be thoroughly treated in the acute stage, will not become chronic pelvic inflammatory disease. Chronic pelvic inflammatory disease may not lead to tubal nowhere and infertility if it can be treated seriously and thoroughly in time. For another example, male mumps often cause orchitis. If treated early, orchitis can be avoided and will not affect the occurrence of * * *.
In addition, some infertile patients have had irregular menstruation or intrauterine adhesions due to abortion or cervical polypectomy, which have affected fertility.
A happy mood reduces mental stress.
Having children after marriage is the hope of both husband and wife, but they are often too eager to get pregnant. Especially the elderly or those who have been married for several years and are not pregnant, they are more nervous and interfere with neuroendocrine function. If you are in a state of high tension and anxiety for a long time, it will lead to the woman's lifelong infertility.
In addition, we should have healthy and reasonable eating habits. Less sugar, less fat, avoid eating foods containing preservatives and colorants. Abstain from obesity, exercise more, and unmarried and childless people should not use sexual health products easily.
Don't miss the best reproductive age.
The fertility of every adult will gradually decrease with age. The best conception age for women is generally 24-30 years old, and that for men is 27-35 years old. Because at this age, both men and women are not only energetic, but also healthy in all aspects, and the quality of eggs and eggs is better, which is conducive to prenatal and postnatal care.
