Hello everyone! I am Dr. Yang, the key content of this article "giving birth", the following is popular science for you.
The birth of a child is the key for a lively and cheerful girl to become an intellectual mother, and it is also the bond that holds the family together, and if there are no children, the family may not be perfect. Of course, I am just a personal opinion, now that people are gradually opening up their minds, they will choose to live in the world of two people all the time, and do not plan to have children.
Either way, live your own life and be happy. But some netizens asked the question, if a woman does not use contraception when she is in married life, how many times can she get pregnant, that is, how many children can she have? According to this question, let's follow me to find out!
First, understand how women get pregnant
Childbirth is a very important event in a woman's life, and if a pregnant woman wants to give birth to a healthy baby, she must not only experience the pregnancy period in October, but also endure the severe pain during childbirth, and the bitterness can be imagined. For women, children are not only the continuation of life, but also the bond that sustains the life of the couple.
First, follicles grow in the ovaries, and after the follicles mature, the eggs are released, picked up by the umbrella end of the fallopian tube, and transported to the ampulla of the fallopian tube, where they are fertilized with sperm to form a fertilized egg. The fertilized egg divides and develops into an embryo, which is transported by the fallopian tubes to the uterine cavity.
The embryo finds a suitable position to start implantation, and after successful implantation, trophoblasts secrete a certain concentration of chorionic gonadotropin, and the detection of chorionic gonadotropin in the blood can confirm pregnancy.
The uterus changes the most during pregnancy, and as the pregnancy continues, the uterus gradually expands beyond the pelvis. The uterine fundus produces two transverse fingers at the highest level of xiphoid process, and delivery is not possible until about 40 weeks.
In addition, uterine blood flow increases, ovulation of the fetus and the development of new follicles all stop, the fallopian tubes elongate, the vaginal mucosa becomes soft and hyperemic, etc.
Second, without contraception, how many children can a woman have in her life?
From the first menstrual period to menopause, the number of eggs released each month is one or two, therefore, 400~500 eggs can be laid in a lifetime. A woman can produce more than 400 eggs in her lifetime, and it stands to reason that there should be more than 400 chances of conception.
But in reality, a woman's chance of conceiving in her lifetime is far less than 400 times, and under the premise of absolute conception, there are nearly 500 chances of conception. For healthy and normal women, the optimal age for childbearing is 23-29 years old, and if you follow the above calculation method, only 84 eggs will be produced in these years.
It is recorded that a woman named Valentina Vasiliev gave birth to 69 children. Valentina was born in the early 18th century, and from the age of 15 she experienced 27 births, including 16 sets of twins, 7 pairs of triplets and 4 sets of quadruplets, giving birth to a total of 69 children.
In Valentina's lifetime, there has never been a single birth, which is miraculous in human history. And now our country advocates a three-child policy, 69 is 23 times, if each family has three children, it is almost equivalent to 23 families.
But these are the children of a woman, and this woman is very great in a way. If a family does not use contraception, there may be many children, but perhaps it is easy to have children, difficult to raise children, and having too many children is not necessarily good for your health.
Some mothers, even if they are in good health, should pay attention to their physical health and do not easily try to have multiple children. Women are naturally weak, while mothers are strong, take good care of your body after giving birth, and don't accidentally get sick.
Third, during pregnancy, expectant mothers try to do these 3 things well
Get regular sleep
During pregnancy, if a woman often feels pronounced tinnitus, it can be improved by a reasonable schedule. In the case of adequate sleep, mental status will also improve, immune function will also increase, and many adverse symptoms will be improved.
Therefore, during pregnancy, pregnant women must maintain regular sleep, go to bed early and get up early, and sleep no less than eight hours a day, which is conducive to the health of pregnant women.
Pay attention to hygiene
After pregnancy, a woman's body changes and the need for nutrients increases, so the body's metabolism will be very fast and the amount of vaginal discharge will increase.
Therefore, pregnant women are easily infected with bacteria, so pregnant women should pay special attention to their own hygiene, bathe frequently, and change underwear frequently. If you don't want to take a bath, remember to scrub your body and change into new underwear.
Timely folic acid supplementation
People pay attention to eugenics and fertility, so for the health of the fetus, folic acid will be supplemented during the pregnancy preparation period before pregnancy. Folic acid supplementation can prevent fetal malformations, and during the first pregnancy test, doctors will also recommend that pregnant women supplement folic acid in time.
Moreover, the hospital and the Women's Federation also distribute folic acid free of charge, which can be received free when it is about to give birth, and for the healthy development of the fetus, folic acid must be supplemented in time even if money is spent. This is good for the mother and also helps the child to thrive, which is important for the child's later life.
