What is the reason for no fetal heartbeat at 50 days of pregnancy?

Pregnancy is the time when a family is most worried, and at this time everything needs to be done properly. Many pregnant women need to be checked at a certain time period. One of the situations that occurs at 50 days is that the fetus has no fetal heartbeat. So the following will introduce the reason why there is no fetal heartbeat at 50 days of pregnancy. The editor will explain it to you below, and I hope you can understand this situation.

1. Endocrine disorders: During the early development of the embryo, three important hormone levels are required: estrogen, progesterone, and human chorionic gonadotropin. As for the mother, if her own endogenous hormones are insufficient, she cannot meet the needs of the embryo, which may cause embryonic arrest and miscarriage.

2. Poor luteal function: Luteal insufficiency can cause delayed endometrial development and a short luteal phase, thereby affecting the implantation of the fertilized egg or early pregnancy miscarriage.

3. Uterine abnormalities: unicornuate uterus, didelphys, septate uterus and bicornuate uterus; intrauterine adhesions; uterine fibroids and endometriosis;

4. Chromosomal factors: Genetics is one of the male factors that cause habitual miscarriage. Among them, chromosomal abnormalities and balanced translocations in men can cause their wives to have miscarriages.

5. Sperm factor: poor quality. It is possible to get pregnant with abnormal sperm, but the pregnancy is likely to result in miscarriage.

How long does it take for a fetal heartbeat to appear during pregnancy?

The fetal heart rate is the heartbeat of the fetus. After pregnancy, the gestational sac, fetal bud and fetal heart rate will grow in a certain period of time. This is also a way to detect the healthy development of the fetus.

Generally speaking, the fetal heart rate can be measured by instruments as early as the 10th week of pregnancy. Currently, the more commonly used high-sensitivity Doppler instrument can hear the heartbeat like the sound of horse hooves when the fetus is 10 or 12 weeks old. However, some hospitals may use a regular stethoscope, in which case the fetal heartbeat cannot be tracked until 17-18 weeks.

There is also a situation where, in the early stages of pregnancy, due to the position of the fetus or other interfering factors, such as excessive maternal fat, the fetal heartbeat cannot be heard even with extremely sophisticated instruments.

The above content has introduced to you the reasons why there is no fetal heartbeat at 50 days of pregnancy, so you can know the reason. This is a wake-up call for women who have just become pregnant. They must do a better job of avoiding these problems to be responsible for themselves and their fetuses.
