After the expectant mother knows that she is pregnant, the most important thing to know is whether it is a male treasure or a female treasure in her stomach, and there are several relatively safe and reliable methods for determining the sex of the fetus in medicine.
How does the doctor determine the sex of the fetus?
1. Determine the sex of the fetus by ultrasound examination
At 14 weeks of pregnancy, the sexual organs have been able to fully distinguish the sex of the fetus, at this time the doctor can see the shape of the external genitalia of the fetus by giving the pregnant woman a B ultrasound examination, so as to distinguish the baby's sex, the accuracy of the female treasure detection is 85%, and the accuracy of the male treasure detection is 95%.
2. Use saline to rinse the uterus to determine the sex of the fetus
This method can be implemented when the expectant mother is 9 weeks pregnant, the accuracy can reach 98%, but this method can only detect the sex of the fetus, and it is not possible to know whether the fetus's chromosomes are abnormal, and the expectant mother cannot have sex within a week before doing this test, otherwise it will affect the accuracy.
3. The sex of the fetus is determined by villous sampling
Expectant mothers can do this test at 8 to 10 weeks of pregnancy, the accuracy can reach 98%, the main purpose of this test is to check whether there are abnormalities in chromosomes, non-special requirements, doctors generally do not recommend pregnant women to do this test.
Of course, in addition to the above three methods, medicine can also detect the sex of the fetus through amniocentesis and villus retrieval, but these two tests have a common impact, that is, they may miscarry in pregnant women, although the probability is very small, only 1% to 5% of the probability, so the medical community does not approve of doing these two tests only for the purpose of measuring the sex of the fetus.
Another method is blood test: by taking the mother's blood, using genetic engineering technology, to determine the sex of the fetus, there will be no danger to the fetus, but according to clinical data and evidence, the proportion of fetal sex errors is quite high, this test can also be said not to be a reliable test.
At present, the detection of fetal sex through medical means is prohibited by national civilization, but there are also provisions that doctors cannot tell anyone about the sex of the fetus except for the diagnosis of the cause of diseases inherited by certain sexes.
In the following cases, the doctor will voluntarily inform the sex of the fetus
1, some diseases will only be inherited to the male treasure, such as: red and green blindness is generally more likely to inherit boys, husband and wife have color blindness or color blind carriers, it is recommended not to have boys. The doctor will also inform the pregnant woman of the sex of the fetus, and the baby's departure will be left to the mother-to-be.
2, expectant fathers with fava bean disease more than 90% will be inherited to the male treasure, fava bean disease after the onset of anemia, yellowing of the skin, liver and spleen enlargement, urine soy sauce color, etc., if not treated in time, can cause liver, kidney, or heart failure, or even death.
Doctors will also take the initiative to inform the sex of the fetus, it is recommended to keep the female treasure, if the mother-to-be carries the gene of fava bean disease, the genetic probability of giving birth to the boy is quite large, it is best to choose the baby girl.
3, the next generation of hemophilia patients is quite likely to be inherited, hemophilia is a very dangerous blood disease, even if it is a slight trauma may cause the patient's blood flow is not stopped, can not coagulate, the risk factor is high, hemophilia patients will take medical measures to determine the sex of the fetus after pregnancy, it is recommended to keep the female treasure.
4. If there is breast cancer, cervical cancer, and ovarian cancer in the immediate family, the probability of future diseases after giving birth to a daughter will be several times higher than that of ordinary people, so these situations should be explained to the doctor, and it is recommended that the family boy in this situation is more appropriate.
5. As long as one of the spouses has congenital heart disease patients inherited to their children, the possibility of congenital heart disease patients should consult a doctor if they want to have children, and follow the doctor's advice before deciding.
Pregnant with a life responsibility is very large, before pregnancy should be relevant consultation, especially the above situation of the couple must be carefully considered, after the actual explanation of the situation, the doctor will be based on the actual situation, the use of medical means to control the sex of the fetus.
Folk have a lot of male and female judgment methods, such as looking at the mother's belly as the standard, the tip of the stomach for the male treasure, the belly round for the female treasure, and some to the taste of the expectant mother, like to eat sour food is the male treasure, like to eat spicy food when the female treasure, in fact, these statements have no scientific basis.
