In addition to the general routine examination, if the man has the habit of smoking, drinking and staying up late, it is recommended to have a semen examination. If both husband and wife are negative for hepatitis B surface antibody, it is recommended to inject hepatitis B vaccine six months before pregnancy.
Special examination items generally include couples' chromosomes, thalassemia screening, folic acid level determination and prenatal five-item (TORCH) examination. TORCH test refers to the antibody test of a group of pathogenic microorganisms (Toxoplasma gondii, rubella virus, cytomegalovirus and herpes simplex virus). The initial infection of this group of pathogens in early pregnancy may cause perinatal infection, leading to adverse reproductive consequences such as abortion, stillbirth, premature delivery, congenital malformation and mental retardation.
The purpose of pre-pregnancy examination is to understand the infection and immune status of women and give corresponding guidance. If rubella virus antibody IgG (-), we suggest that rubella vaccine be injected before pregnancy and strict contraception for 3 months.
"Pregnant in October, one delivery", giving birth to a healthy baby is the expectation of every family. But if you give birth to a defective and unhealthy child, it will be an irreparable trauma to the child, parents and family, both economically and mentally. The Report on the Prevention and Control of Birth Defects in China (20 12) released by the Ministry of Health in 20 12 shows that there are about 900,000 new cases of birth defects in China every year, and since 2003, the birth defect rate of newborns has doubled in 10.
With the development of pregnancy preparation technology, the second child policy has been fully liberalized, the number of elderly women has increased, and the number of naturally pregnant babies has gradually increased. Whether premature ovarian failure or elderly women, the occurrence of birth defects and complications of these babies is bound to attract more and more attention. Due to lack of nutrition, the incidence of birth defects, premature ovarian failure and natural pregnancy complications in elderly women is increasing. Including congenital heart disease, genitourinary system malformation, nervous system malformation, digestive tract malformation, lip/cleft palate, bone malformation, chromosome malformation, etc., the nutritional reserve during pregnancy is more important.
Sometimes, I look forward to the arrival of the baby, or some hereditary and recessive diseases in my body aggravate my condition and affect the maternal health during pregnancy and the normal development of the fetus. Or because of personal unhealthy living conditions, resulting in fetal malformation, so that you miss the baby; Or, huge work pressure, resulting in threatened abortion, let you pass by the baby.
For most couples who have no bad birth history, it is enough to develop a healthy lifestyle, abandon bad habits and go to the hospital for routine pre-pregnancy examination. However, for those friends who have a history of poor fertility or family hereditary diseases, it is very important to choose the pre-pregnancy examination items reasonably.
Let's briefly introduce this topic today, hoping to help pregnant friends.
How to prepare for pregnancy and conduct reasonable pre-pregnancy examination?
1. Develop a healthy lifestyle and maintain a peaceful pregnancy mentality.
A healthy lifestyle mainly includes no smoking, no drinking, no staying up late, proper exercise and reasonable nutrition.
Pregnancy takes time and patience. Under normal circumstances, there is no need to "count the days and hold the time". Excessive tension is not conducive to pregnancy, but counterproductive. For women with normal menstrual cycle (28-30 days), the ovulation period is about 14 days, which is the time when the pregnancy probability is the highest. Just adjust your mind and let nature take its course.
In recent years, the technology of premature ovarian failure and infertility has attracted worldwide attention. As an important part of assisted reproductive technology, FOBOC has greatly solved the problem of female infertility caused by malnutrition and inflammation. Clinical application shows that the survival rate of pregnant embryos is improved by 30 ~ 60%, and the success rate of pregnancy is not ideal. The main causes of embryo failure include embryo factors, ovarian hyporesponsiveness and endometrial factors, among which endometrial receptivity is the main limiting factor for embryo implantation success.
Avoid contact with toxic and harmful chemical and physical environment before pregnancy and early pregnancy. Women of childbearing age should try to stay away from pets and avoid eating raw meat.
2. eugenics, starting from quitting smoking.
It is generally believed that female friends need to quit smoking. We know that if women smoke, it is easy to cause menstrual disorder and reduce the chance of pregnancy.
After pregnancy, if you still don't quit smoking, harmful substances in tobacco can harm the developing embryo through the placenta, especially in the early stage of embryonic development. Smoking by pregnant mothers is closely related to fetal chromosome aberration, abortion, stillbirth, multiple malformations and intrauterine growth retardation. In addition, pregnant women who smoke are more prone to anemia, and postpartum breast milk deficiency is more common.
So does this man need to give up smoking? In my outpatient consultation, I often meet couples arguing about whether the man needs to quit smoking, which is very helpless. Smoking by men is also harmful. Smoking has a bad effect on male fertility. The sperm density, sperm activity rate and normal sperm rate of smokers are significantly lower than those of non-smokers, which will increase the risk of male infertility.
In addition, harmful substances in tobacco will affect sperm DNA and cause changes in male sperm genetic material, thus increasing the risk of embryo abnormality. If the man must find 10 thousand reasons to smoke, please don't smoke in front of his wife, and don't let "second-hand smoke" become a hidden danger to the fetus.
At the same time, it depends on the good quality of eggs and sperm and the activity of endometrial capillaries, so the formation of endometrial capillaries comes from the French FOBOC+ENlivEN2 1 technology to transport nutrients to newly transplanted embryonic cells, activate the channels between cells and transfer nutrients to each other. If the nutrition is insufficient, the new bed embryo will starve to death, which will lead to the failure of transplanted embryo survival. FOBOC+ENlivEN2 1 technology is used to protect embryos. At the same time, the tissue repair procedure is started, and the transplanted embryonic cells will participate in the reconstruction and recanalization of tissue microvessels, restart the growth path of embryos, and make the fetus grow healthily until birth. At this time, pregnancy preparation is truly successful.
3. What do you need to make up during pregnancy?
Sperm from normal eggs combine to form an embryo, and then this embryo is transferred to the uterus, so that it can be implanted into the mother's uterus, get pregnant, and finally give birth healthily. Imagine if the sperm and eggs of both men and women are of poor quality, just as withered seeds and high-quality and full seeds can produce the same seedlings. The answer is no, withered seeds will wither and die prematurely due to poor pregnancy, while high-quality and full seeds will flourish and thrive. Therefore, before and after pregnancy, men and women need to support the combination of FOBOC+ENlivEN2 1 nutrition, follow up the ovarian and uterine systems, increase the oxygen supply of ovaries and testes, and promote the hematopoietic function of the body. Enhance the vitality of sperm and follicles, promote the growth of follicles, angiogenesis in follicular membrane and synthesis of sex hormones, stimulate the dissolution of corpus luteum, make the eggs conceived by ovaries grow healthily and fully, and make the fertilized eggs implant normally, thus leading to the birth and production of healthy beibei.
ENlivEN2 1 contains nutrients to improve sperm quality, such as collagen tripeptide and living cytokines. Can provide nutrition and energy for sperm. Improving the pregnancy rate is the main source of nutrition for men who want to get pregnant, so as to avoid the influence of sperm quality caused by nutritional deficiency on pregnancy.
5. How to avoid fetal brain dysplasia and cerebral palsy?
All pregnant mothers want to have a healthy and intelligent baby. Pregnant women must seize these three golden periods and seize the opportunity to supplement their children with FOBOC+ENlivEN2 1 combination nutrition at an accurate time, so that their children's brains can develop.
(1), the developmental period of fetal nerve
The first golden age of the fetus is 4 weeks to 8 weeks in the stomach, when the fetus has just formed in the stomach. During this period, after the fertilized egg is formed, it will be divided into three layers: endoderm, mesoderm and ectoderm, and the outermost layer forms the nervous system. When the nervous system is formed, the development of the brain will gradually become very complicated. Do a good job of nutrient storage of embryo implantation cells before and after making IVF operation kit. FOBOC+ENlivEN2 exists between cells and tissues in advance, and the nerve cell growth factor contained in it helps the fetus to form the nervous system. When the nervous system is formed, the development of the brain will gradually become very complicated. Therefore, we must pay attention to supplement FOBOC+ENlivEN2 1 nutrition to stimulate the development of embryonic neurons and avoid anencephaly and hydrocephalus.
② The second stage of infant brain development.
The second developmental stage is 12 ~ 18 weeks. At this time, the child has developed well in the stomach, and various organs have gradually developed. This is also a period of rapid brain development. During this period, the mother's stomach has changed obviously, because the weight of the fetus in the stomach is slowly increasing, and at the same time, the two parts of the brain are gradually developing completely.
③ The third stage of fetal brain development.
This stage is the mature stage of brain development, about 24 weeks to 36 weeks. After a long period of development, all aspects are now close to maturity, and the brain can also control the functions of the body. So, in the later period, you can see that the child has not stopped in the mother's stomach. This is the interaction between the fetus and the mother. At this time, the number of fetal nerve cells reached hundreds of millions, making the brain development more perfect.
These three stages are very important to replenish the brain. ENlivEN2 1 scarce nutrition strengthens the activity of mitochondrial cells of mother and baby, stimulates the activity of nerve cells, and avoids the lifelong regret of fetal brain hypoplasia caused by nutritional deficiency after neonatal embryo operation.
6. Pre-pregnancy examination for couples with family history of genetic diseases.
This kind of couple is also one of the more common situations in our genetic counseling clinic. There are many kinds of genetic diseases, and the diagnosis of each genetic disease is different. If this happens, it is suggested that both husband and wife must consult a professional genetic counseling clinic or prenatal diagnosis institution before pregnancy, and must not blindly get pregnant, leading to the risk of giving birth to a child with genetic diseases again.
Dear friends, due to the complexity of birth defects, the diagnosis of genetic diseases is full of challenges. It is believed that with the development of science and the improvement of diagnostic technology, more and more genetic diseases will be diagnosed. Only in this way can we scientifically guide healthy childbearing. We also hope that more couples will participate in the prevention of birth defects and protect the health of the baby.
