Control the weight of pregnant women for healthu children

Control the weight of pregnant women for healthu children . The latest Danish study: Control the weight of pregnant women and let the children grow up healthily.

In the UK, more than half of pregnant women are overweight or obese, leading to an increased risk of miscarriage and stillbirth. Secondly, children of overweight parents are more likely to gain weight, which leads to type 2 diabetes and heart disease.[Article in British “Daily Mail” January 06, 2021] Title: Health.

Danish researchers studied the fertility and family health status of 9,232 adults. About 9% of them suffer from infertility. When the mother’s body mass index (BMI) ≥ 25 during pregnancy, the Male babies are at a higher risk of infertility, however, the same situation does not seem to apply to girls born to overweight mothers. A series of physical changes such as inflammation, hormone disorders or mineral deficiencies caused by obesity can slow down the development of the fetus.

In the UK, more than half of pregnant women are overweight or obese, leading to an increased risk of miscarriage and stillbirth. Secondly, children of overweight parents are more likely to gain weight, which leads to type 2 diabetes and heart disease. A study pointed out that sons born to overweight mothers before pregnancy are 40% more likely to develop infertility after they grow up.

Research report author Linn Arendt, an epidemiologist at Aarhus University in Denmark, said: “Infertility is a global public health problem. It is important to focus research on addressing risk factors, whether in the short term or In the long term, children born to overweight or obese mothers face a higher risk of adverse effects.”

In the past 30 years, the incidence of infertility has risen sharply. Among all the current couples, one-eighth of couples have failed to become pregnant after at least one year of hard work. Experts say that 1/3 of infertility is due to male reproductive problems, 1/3 of infertility is due to female reproductive problems, and the last 1/3 are due to reproductive problems of both men and women or other unknown factors.

According to Dr. Arendt and her colleagues, the obesity epidemic may exacerbate the problem of rising infertility rates. Dr. Arendt said: “These findings further prove that the mother’s weight during pregnancy may also affect the future reproductive health of the baby boy. Therefore, preventing overweight during pregnancy may be an important means to protect the fertility of offspring.”

The mother’s overweight may affect the reproductive health of the offspring through several potential mechanisms. For example, fat tissue has hormonal activity, and fetal exposure to leptin, androgens and estrogen may interfere with the development of the reproductive system and may trigger changes that only appear at sexual maturity Some endocrine-disrupting chemicals will accumulate in adipose tissue and become bioavailable substances in the process of reshaping maternal fat reserves during pregnancy, and enter the blood of the mother and fetus; obesity is also related to mild metabolic inflammation, which It is also one of the factors recommended in the Early Reproductive Health Program.

Past studies on boys and girls have shown that mothers’ overweight may be related to precocious puberty and other hormonal indicators of reproductive health, and it has been found that overweight pregnant women can increase the risk of genital deformities in boys and reduce semen quality. Dr. Arendt said that no previous studies have investigated the relationship between pregnant women’s overweight and their children’s infertility. Their research supports the hypothesis that pregnant women’s overweight affects the reproductive health of male offspring, but further research is needed.

A previous study in the United States found that boys born to obese mothers had poorer athletic ability at the age of three, and had lower IQ scores at the age of seven. Therefore, obese women are advised to lose weight before pregnancy. This is important for themselves and their children. Health is good. However, the NHS warns that trying to lose weight during pregnancy is not recommended because it may be unsafe, and there is no evidence that losing weight during pregnancy can reduce complications.

Causes of male infertility

The most common reason is poor semen quality, and possible reasons for abnormal semen include: insufficient sperm count, abnormal sperm motility, and abnormal sperm shape. Many causes of abnormal semen conditions cannot be explained. For example, there is a link between increased scrotal temperature and decreased semen quality, but it is uncertain whether wearing loose underwear will increase fertility. Damage to the testicles can also seriously affect the quality of semen. The reasons for the damage may be: testicular infection, testicular cancer, testicular surgery, congenital defects, testicular damage, etc.

If some men do not want to have children (again), they will choose a vasectomy, which involves cutting off and sealing the tube that drains the sperm from the testicles (the vas deferens) so that the semen no longer contains any sperm. Vasectomy can be reversed (to repair the tube), but the success rate is very low.

Hypogonadism is an abnormally low testosterone level, which can be caused by tumors, taking illegal drugs, or Kranfelter syndrome. Certain types of drugs can sometimes cause infertility problems, such as sulfasalazine, anabolic steroids, chemotherapy drugs, herbal therapies, illegal drugs (marijuana, cocaine), etc.
