Patient's question:
Can non-invasive methods determine the gender? My first child is a girl, so this time I want a boy. I don't know how to interpret the results.Doctor's answer:
Non-invasive deoxyribonucleic acid can detect the sex of the fetus. The fetal free deoxyribonucleic acid is mainly extracted from the mother's venous blood. Although this method can detect the sex of the fetus, it is important to pay attention to the time limit. Generally, non-invasive deoxyribonucleic acid testing is performed between the 12th and 20th weeks of pregnancy. Although non-invasive deoxyribonucleic acid can monitor the sex of the fetus, comprehensive hospitals will not reveal the sex of the fetus to the pregnant woman. Non-invasive deoxyribonucleic acid is best checked on an empty stomach, but generally, appropriate diet will not affect the test results. The sex of the fetus is determined by the male gene, and the quality of male sperm has a great impact on the offspring.
