The need to find out the sex of a child before birth can be due to both objective reasons and simple curiosity. On the Internet, magazines and books, you can find many methods for determining the sex of a baby using information about parents, date of conception, and much more. But these methods, unfortunately, are not highly reliable. If the desire to determine the sex of the child is great, you can resort to the help of medicine.
A simple and non-invasive method is an ultrasound examination of the fetus. If you want to use it, ask your obstetrician-gynecologist who monitors the pregnancy to prescribe this procedure for you. But do not hope that the result will be absolutely accurate. Sometimes it happens that the doctor does not manage to get an image of the desired part of the fetus at all. Mistakes are also common, especially in early pregnancy. By the way, it is believed that the sex of the child by ultrasound cannot be determined until the 12th obstetric week. Accordingly, this method is not suitable for early gender diagnosis.
If there is a serious need to find out the sex of the fetus in the early stages of pregnancy, a genetic analysis of its cells can be performed. To do this, select a laboratory that provides procedures such as amniocentesis, cordocentesis, or chorionic villus sampling. All of them are a collection of material from the membranes of the fetus, which have the same genotype as that of the child. In the future, the resulting cells are sent to the laboratory to determine the chromosomes responsible for the sex. The material is extracted using a special needle, piercing the mother's abdomen and the shell of the fetus, which increases the risk of miscarriage. Therefore, such a procedure should be done only if you have had genetic diseases related to gender in your family.
In addition, it is possible to determine the sex of the child by analyzing the blood of the expectant mother. This method is based on the presence of a small number of fetal cells in the maternal bloodstream. If the analysis reveals a Y chromosome, it can be argued that the fetus is male. The procedure can be performed from the 7th week of pregnancy. The researchers believe that the accuracy of the analysis can be close to 100%, but the method has not yet been widely applied.
