Is fetal heart rate of 160 normal?

If the test result is a fetal heart rate of 160, the fetal heart rate is a little fast, but the degree is not very serious. In fact, a fetal heart rate of 160 is still within the normal range, but it has reached the peak of the normal range, so it should be taken seriously at this time. Next, follow the doctor's instructions and perform fetal heart monitoring regularly. If the fetal heart rate is found to be higher than 160, relevant examinations are required. After understanding the cause, timely symptomatic treatment is required.

Is fetal heart rate of 160 normal?

The fetal heart rate has nothing to do with the sex of the fetus.

Generally, the heart rate of more than 5 prenatal examinations is around 140 beats/minute. Especially those below 140 beats/minute are usually boys, and around 150 beats/minute, especially those above 150 beats/minute, are girls, which account for the majority. The later the pregnancy is (after 7 and a half months), the more obvious the gender difference can be distinguished. Of course, this does not mean that an occasional prenatal examination of the fetal heart rate can prove the gender. The examination report must be repeated many times and stay within a certain range. Then the general gender can be distinguished with an accuracy.

Why can't we use one or two fetal heart rate measurements to determine the gender of the baby? Because sometimes a female fetus happens to fall asleep when the doctor listens to the fetal heart rate, and the fetal heart rate will be lower than normal. Sometimes a male fetus happens to be moving in the mother's belly when the doctor measures the fetal heart rate, so the fetal heart rate will be higher than normal, even exceeding 145 beats/minute. Therefore, multiple prenatal examination reports of the expectant mother are required to roughly determine the gender of the baby.

When is the sex of the fetus determined?

Generally speaking, the gender of the fetus can only be roughly identified based on the different shapes of its external genitalia when it is separated from the mother's body. Those who have a "little penis" are boys, and those who don't have one are naturally girls. In fact, the true difference between men and women is determined the moment the sperm and egg combine to become a fertilized egg.

The embryo has to go through a long 10 months (about 40 weeks) of differentiation and development in the mother's body before it can come into the world. Under normal circumstances, when the embryo develops to 8-10 weeks, the male fetus will develop testicles and begin to secrete androgens, which cause the fetus's external reproductive organs to develop and change in the male direction. A fetus without testicles will naturally develop its external genitalia in the female direction due to the lack of androgen.

Related information shows that the sex of the fetus depends on whether the sperm that combines with the egg carries the X or Y gene. However, during one ejaculation, there can be hundreds of millions of sperms. Whether the sperm carrying X or Y combines with the egg is completely accidental and a matter of chance, and is not controlled by the parents' will.
