What are the children born from IVF? IVF, like a naturally pregnant child, is healthy and smart, and it will not be said that IVF has a higher risk of defects. There are also data showing that children born in test-tube babies have better intelligence and behavioral ability than normal children at the age of two or three. Don't talk about this. In fact, children's defects and health problems are more related to their parents.
The incidence of cerebral palsy in IVF is twice that of normal pregnant women, mainly because the women who are IVF are generally older, mostly over 30 years old. These couples generally have their own problems, sperm and eggs are not very good, so the chances of children having problems are higher. How many esophageal babies are healthy?
In theory, IVF can transplant multiple embryos, and then it can achieve the goal of twins or multiple births. However, the twins formed by transplanting multiple embryos are not exactly the same, that is to say, the twins grow up in the same way as ordinary brothers and sisters, not identical twins. In addition, it is necessary to make a comprehensive judgment according to the age of an individual. If it is an elderly woman, it is not recommended to transplant multiple embryos in principle, otherwise it may lead to multiple births, and subsequent fetal reduction surgery may be needed, and the risk will be higher. In addition, it is uncertain how many embryos IVF has succeeded. If only one or two embryos succeed, it is basically difficult to be twins.
Can IVF choose men and women? IVF is not allowed to choose men and women, and national laws explicitly prohibit fetal sex selection. Now that we have reached a highly civilized modern society, any couple should no longer prefer sons to daughters. Choosing men and women is against the laws of nature and society. If the ratio between men and women is unbalanced, it will have a very bad impact on society. But there is a special situation where men and women can be chosen, such as genetic diseases. Some diseases will be passed on to boys, and some diseases will only be passed on to girls. If you have this disease, you are allowed to choose between men and women.
However, in China, illegal sex selection of fetus is prohibited by law, and IVF technology is not allowed to be used for sex selection at will. Therefore, artificial insemination is optional, but general hospitals will not choose the sex of the fetus according to the wishes of both husband and wife.
First of all, it is necessary to make a detailed gynecological examination of infertile women after artificial insemination, to check whether the internal and external genitalia are normal, whether the endometrial biopsy gland secretion is good, and whether the bilateral fallopian tubes are unobstructed. If all these are normal, you have the conditions to accept artificial insemination.
Then we need to predict the ovulation date to choose the best fertilization time. The commonly used methods to estimate ovulation date are: measuring basal body temperature and cervical mucus 4-5 days before ovulation, and the woman estimates that before ovulation, the sperm donor or husband masturbates and takes out semen, which needs to be tested. If the results show that the semen density and activity are normal, after the semen is liquefied, inject it into the vagina, around the cervix and in the cervical canal with a syringe or catheter, and the woman will stay in bed for 2-3 hours to prevent the semen from being discharged, or continuously measure it near the ovulation day.
