Can palace records from the Qing Dynasty really predict whether a boy or a girl will be born? Are more multiples better? Is painless abortion really painless? Can I still take medicine while pregnant? Have you mastered the pregnancy preparation period? Faced with all kinds of questions, the young couple may not be able to get clear answers for a while.
Pregnancy is a natural process. Men must have normal sperm, and women must have good eggs. After normal ovulation, when the fallopian tube peristalsis function is good, the sperm and egg meet and combine, and the fertilized embryo passes through the fallopian tube. Back to the uterus, the environment of the uterus must be good. The so-called right time and place are so-called, so that the embryo can implant. Professor Ma Caihong, chief physician of the Reproductive Medicine Center of Peking University Third Hospital, said in an interview that babies must have a balanced diet, a good daily routine and the best mental state. Expected.
The ovaries wait for no one
A woman\’s fertility reserve is highest during the 22nd week of pregnancy. At that time, the ovaries have the largest number of follicles, with 6 million to 7 million. When a child is born, there are only 2 million follicles, and then a large number of follicles begin to lock up. By puberty, only 300,000 are left. After the age of 35, the rate of follicular atresia accelerates sharply. Ma Caihong said that women’s fertility reserves are blocked every month. Although girls nowadays have good skin care products and look young, their ovaries are not waiting for others. The number of follicles tells her age. There are currently no drugs or food nutrients that can slow down the aging of organs such as the ovaries.
Generally speaking, as long as a woman has menstruation, she has the possibility of pregnancy. But being a mother is not that easy. First of all, we must take on the important task of educating children, complete a certain amount of studies, have certain knowledge and foothold, and reach a certain level of personal maturity. Ma Caihong recommends that women get pregnant after the age of 22, preferably before the age of 30.
It is understood that you need to be in good health before becoming pregnant, and a physical examination should check liver function, kidney function and heart function. In addition, the reproductive system should be checked to see if there is inflammation or infection in the fetus or uterus. Women during pregnancy should pay attention to the functions and metabolism of themselves and their fetus, and the functions of major organs such as the heart, kidneys, and liver should be maintained in good condition. The development of female egg cells will be recruited in about a month, and they should not be exposed to adverse factors, such as radiation and experimental reagents containing toxic substances, within a month.
The risk of going against nature
Pregnancy after ovulation generally takes 28 days as a cycle, and ovulation occurs on the 14th day. Sometimes ovulation will be advanced or delayed, and B-ultrasound can be used to monitor it. Moreover, the couple\’s life must be regular, because sperm can survive outside the body for 3 days. Before ovulation, it is best for the sperm to wait for the egg and conceive on the 12th to 14th day. About 14 days after fertilization, pregnancy test strips can be used to detect. Introduction by Ma Caihong.
Through natural selection, most fertilized embryos are normal. After fertilization, due to the development of the embryonic neural tube, folic acid needs to be supplemented. It is generally found in large leafy vegetables and can be consumed through a balanced diet. Folic acid tablets can also be supplemented before pregnancy.
Talking about some people who want to have twins or multiple births and take some ovulation-inducing drugs, she pointed out that any behavior that goes against nature is risky. Twins are prone to premature birth and miscarriage. Premature infants have abnormal neurodevelopment and cannot sit or stand, and many of them have cerebral palsy and malformations. She said: After multiple births, it is recommended to selectively reduce the number of fetuses. Fetal reduction can be performed at 6, 13 or even 20 weeks of pregnancy. If multiple births are not suitable, the number of births should be reduced in time.
It is understood that many pregnant women often suffer from various complications during pregnancy and delivery, such as miscarriage, fetal malformation, intrauterine growth retardation, anemia, gestational hypertension, diabetes, polyhydramnios, placenta previa, premature birth, etc. , seriously threatening the safety of mothers and children. In addition, bleeding does not mean that you are not pregnant. It could be a threatened miscarriage or an ectopic pregnancy. If you have light menstruation or are not using contraception, you still need to test whether you are pregnant.
Abortion increases risk of infertility
Typically, infertility is diagnosed when you have regular sex every month without using contraception. Female factors account for about 30% of infertility, male factors account for about 30%, 10% to 20% are caused by both parties, and 10% to 20% cannot find a clear cause. Most of them are caused by acquired factors. Congenital causes are relatively rare, about 5% to 10%. Ma Caihong said.
She said there are many external factors that interfere with implantation of a fertilized egg. If mental factors are bad, such as scientific researchers who are particularly nervous and anxious and often stay up late to write papers, it may interfere with the endocrine axis, affect ovulation and menstrual cycles, lead to poor ovulation, and poor luteal corpus function. In addition, excessive fatigue leads to reduced resistance and vulnerability to infection and inflammation. Some unhealthy lifestyles, such as drinking and smoking, will affect the quality of reproductive cells.
Some young women choose to have abortions due to unwanted pregnancies. Repeated miscarriage within a short period of time is an important factor leading to uterine damage, which can easily lead to endometrial damage, intrauterine adhesions, pelvic adhesions, and secondary infertility. Usually doctors cannot see the uterine cavity during abortion surgery, which is a \”blind surgery\”. A small number of cases often cause uterine damage or even perforation due to failure to check the position and size of the uterus before surgery, the direction of instruments entering during surgery does not match the curvature of the uterus, or excessive force. About half of our patients have a history of abortion. This has happened a lot. As long as an artificial abortion is performed, regardless of the size of the fetus or the length of its life, it may cause damage to the endometrium. Ma Caihong emphasized that for painless abortion, you must find a highly skilled doctor. If you still need to have a child, you must be especially careful. Without the feeling of painless abortion, it may cause damage to the endometrium and increase the occurrence of complications. Uterine contractions can cause bleeding through the fallopian tubes into the pelvic cavity, which increases the risk of endometriosis.
