Why can't you get pregnant with your second child? 10 truths about why you can't get pregnant with your second child

After the second-child policy was opened, many parents hope to have a second child, which can not only make the child no longer lonely, but also cultivate the child to learn to share and be less selfish. Many people are confused about why they can't have a second child. What is the reason for not having a second child? 10 truths about why you can't have a second child. The editor of No. 5 website will answer them one by one for you!

What is the reason for not being able to conceive a second child?

1. Fallopian tube factors:

Clinical data show that many mothers fail to conceive because of blocked fallopian tubes. The fallopian tubes are responsible for transporting eggs from the ovaries to the uterus. Damage to the fallopian tubes prevents sperm from coming into contact with the egg. Recurrent pelvic inflammatory disease, endometriosis, and improper termination of pregnancy can all cause damage to the fallopian tubes.

2. Hormonal factors:

In the case of abnormal ovulation, the corresponding hormones cannot rise normally. The ovaries cannot release mature eggs, and the endometrium cannot thicken normally. These ovulation abnormalities can be detected through blood tests of hormone levels. In the preparation period for pregnancy, it is inevitable to be a little anxious. In fact, the following methods can help you increase your pregnancy rate:

1. Regular exercise not only improves your physical and mental health, but also reduces mental stress, broadens your mind and improves sleep quality.

2. Get a comprehensive health check-up and go to the hospital to check if you are in good health.

3. To know the time of ovulation, you can record a menstrual cycle - ovulation usually occurs 14 days before the next menstrual period, determine the time of body temperature rise, and use ovulation chemical test kit to detect. Have sex at least every other day during the ovulation period.

4. Quit smoking. Smoking is not only harmful to your health, but also affects the number of your husband's sperm.

5. A balanced diet must include adequate intake of vitamin B2, which is found in meat, fish, eggs and milk. More importantly, folic acid should be supplemented.

From the reasons why we can’t conceive a second child learned from the above conception guide, we can see that there are many factors that affect a woman’s probability of pregnancy. Physical environment and living environment are all factors that affect a woman’s pregnancy. We must develop good living habits and maintain a good mood to conceive a new life.

10 truths about why you can’t have a second child

1. Infertility caused by multiple abortions:

The harm caused by artificial abortion to women is well known, and the more abortions are performed, the greater the harm. This is because repeated scraping of the endometrium thins the uterine wall, which can not only cause menstrual disorders, oligomenorrhea, or even amenorrhea, but can also cause pelvic inflammatory disease, endometriosis, and even fallopian tube obstruction. What's more frightening is that repeated abortions will reduce the possibility of women having children in the future. Not only will it be difficult for women to get pregnant, but even if they do get pregnant, they will easily miscarry.

2. Having given birth to a deformed child and anxious to have a second child:

Some multiparous women gave birth to abnormal children in their last pregnancy, or had habitual miscarriages several times, but the cause has not been found out. If the cause of the deformity in the previous pregnancy still exists, such as bacterial infection, drugs, chromosomal abnormalities, family genetic history, etc., then the possibility of giving birth to an abnormal child in the next pregnancy is still very high. Therefore, mothers should rule out these factors before getting pregnant with a second child to eliminate the possibility of having a deformed child.

3. Chronic constipation leads to impaired fallopian tube function:

Many working mothers always sit for long hours at work and lack exercise, which leads to weakened intestinal motility and thus constipation. Since the uterus, fallopian tubes, ovaries and other organs are located in the pelvic cavity, the left fallopian tube is close to the sigmoid colon and rectum. If chronic constipation occurs for a long time, various pathogens in the feces that often stay in the intestine will invade the left fallopian tube and ovary through capillaries and lymphatic vessels, causing inflammation, resulting in impaired fallopian tube function and causing infertility or ectopic pregnancy.

4. Excessive weight loss affects ovulation:

This is an era where thinness is considered beautiful, and people who are not fat have also joined the weight loss team. American scientists have shown that women must have a certain amount of fat in their bodies to maintain normal menstruation and thus have reproductive ability. Too little fat can easily cause cessation of ovulation or amenorrhea. Mothers who want to have a second child can do more exercise to maintain their body shape and improve their physical fitness.

5. Men’s childbearing age is too old:

The policy of having a second child is now open, but many fathers born in the 1970s are already older. According to an analysis by American eugenicists, the risk of fetal malformation increases by 20% when men over 40 give birth, compared with children born to men under 40. Several common congenital developmental defects are significantly associated with fathers over 35. It is recommended that fathers do a comprehensive checkup before having a second child.

6. Improper or excessive sexual intercourse:

Although the testicles can produce hundreds of millions of sperm every day, the sperm must still mature in the epididymis. After one ejaculation, it takes 5 to 7 days to restore the number of sperm that can produce fertility. Therefore, too frequent sexual intercourse will result in a small number of sperm each time, which can cause infertility. In addition, interrupted sexual intercourse, excessive masturbation or irregular sexual intercourse can also lead to abnormal congestion of the sexual organs, which is not conducive to sperm production. It is better for fathers to abstain from sex appropriately.

7. Excessive smoking and drinking:

Fathers are under great pressure to support their families, and they can't help but smoke a cigarette when they feel sleepy. However, the nicotine in cigarettes can damage sperm, causing a decrease in the sperm content in male semen and an increase in the content of abnormal sperm. Men who have smoked for more than 10 years have a significant decrease in sperm count and sperm motility. Alcohol is a gonadal toxin. If you drink too much, it can cause gonadal poisoning, which manifests as testicular damage, weakened reproductive function, sperm damage, reduction, and reduced activity, and can induce impotence and no ejaculation. Before having a second child, fathers should quit smoking and drinking for at least two months.

8. Harmful working environment causes chromosome aberration:

Some occupations have certain effects on human fertility, such as working in high-voltage lines, substations, radar stations, and electromagnetic wave transmission towers; researchers in toxicology laboratories and those who are exposed to lead, mercury, benzene, cadmium, manganese, arsenic, organic solvents, and polymer compounds; and those who often need to use electronic instruments, medical equipment, and office automation equipment at work. Toxic substances in these occupational environments can damage sperm or eggs and cause their chromosomes to become deformed.

9. Excessive stress leads to mental infertility:

The fast-paced life in the city has caused many people's psychological pressure to gradually "expand" and cannot be released. This pressure is also increasing with age. Psychological research shows that the personality characteristics of mental infertility are mostly dependence, emotional fluctuations, anxiety and depression; some couples are anxious to have children, but they cannot get pregnant immediately. These psychological contradictions can cause tension and mental burden, and can affect the function of women's ovaries through neuroendocrine changes, resulting in infertility.

10. Conception during menstrual depression:

There are cyclical changes in physical strength, emotions and intelligence in the human body. This cyclical change is the physiological rhythm of the human body. When the physiological rhythm is at its peak, people are energetic, emotionally stable and in a good mood. The children conceived at this time will be healthy and intelligent. When it is at its low ebb, the body is easily tired and it is difficult to concentrate. It is possible to give birth to a child with a weak constitution and intellectual problems. It is best to avoid the low ebb when conceiving a second child.

Reasons why women cannot conceive a second child

1. Obesity: A 2009 study published in the journal Fertility and Sterility found that women who were obese at age 18 had a higher risk of developing polycystic ovary syndrome and experiencing infertility problems.

2. Too thin: Women who are too thin usually have insufficient leptin in their bodies. A 2009 Harvard University study found that low leptin levels can cause menstruation to stop.

3. Surrounded by chemical compounds: Studies show that exposure to pollutants, pesticides and industrial compounds can reduce a couple's ability to conceive by 29%.

4. Smoking: Smoking not only reduces the chances of pregnancy, but also harms the developing fetus. According to statistics from the American Society for Reproductive Medicine, smoking causes 13% of infertility.

5. Excessive drinking: Doctors warn that excessive drinking is associated with an increased risk of ovulation disorders. A Swedish study followed more than 7,000 women for 18 years and found that women who drink frequently are more likely to seek infertility treatment.

6. Excessive exercise: Excessive exercise can have a negative impact on female ovulation. A study published in the journal Fertility and Sterility found that women of normal weight who exercise vigorously for more than 5 hours a week will have difficulty conceiving.

7. Drinking too much coffee: A 2011 study by the Nevada School of Medicine found that caffeine affects the muscle contraction that carries the egg from the ovary through the fallopian tube to the uterus, while a 2012 Danish study found that drinking more than five cups of coffee a day would reduce a woman's chances of success with in vitro fertilization by half.

8. Too much stress: A 2014 study published in the journal Human Reproduction found that women who were stressed had higher levels of a certain enzyme and had trouble getting pregnant. The researchers said the study did not suggest that stress alone could cause infertility problems, but that women should control and reduce stress when trying to conceive. Thyroid disease. A 2015 study published in the journal Obstetrician and Gynecologist confirmed the long-held theory that thyroid dysfunction can lead to ovulation and pregnancy problems.

9. Too old: Women’s ovarian function begins to decline significantly after the age of 35, and the rate of decline accelerates greatly after the age of 37. In the 10 years before menopause, the ovarian function is already very fragile.
