There is no way to determine the sex of the fetus in the blood test report. The sex of the fetus is determined by the genotype of the sex chromosomes. The maternity checkups of pregnant women usually check routine blood tests, progesterone, human chorionic gonadotropin, liver function and so on, which are not able to determine the sex of the fetus. It should be noted that at present, China’s laws clearly stipulate that it is illegal to test the sex of a fetus under non-medically necessary circumstances. Regardless of whether the fetus is a boy or a girl, pregnant women need to undergo regular obstetrical examinations in order to monitor the physical condition of the pregnant woman and the development of the fetus at all times, and to ensure that the fetus grows up as healthy as possible.
