What are the most common causes of early miscarriage?

Pregnancy is a behavior that women care about very much, because pregnancy is a necessary process for adding new members to the family and an important choice for giving birth to offspring. However, due to various reasons, modern women have made pregnancy a very dangerous process. For example, the problem of miscarriage has brought great trouble to women. Let's take a look at the most common causes of early miscarriage.

In the early stages of pregnancy, the fertilized egg (embryo) fails to implant in the uterus and is in the early stages of development. The placenta has not yet fully developed and the connection between the placenta and the uterine wall is not yet stable. If you have sexual intercourse at this time, the uterus will be vibrated, which can easily cause the placenta to fall off and cause miscarriage.

If you have sex in the early stages of pregnancy, it is very likely that the prostaglandins contained in the semen will cause the uterus to contract and the cervix to relax, which, combined with the stimulation during sexual intercourse, can lead to miscarriage.

Reproductive organ diseases, systemic diseases in women during pregnancy. Women suffer trauma during pregnancy and experience rapid mood changes. Male sperm quality problems, such as developmental abnormalities, deformities, and chromosomal abnormalities in both men and women.

Termination of pregnancy before 28 weeks of gestation and when the fetal weight is less than 1000g is called abortion. Among them, spontaneous abortion refers to abortion caused by non-human purposes. It is a miscarriage caused by natural factors. 31% of spontaneous abortions occur after embryo implantation, of which more than 80% are early abortions.

According to the different stages of miscarriage development, it can be divided into threatened abortion, inevitable abortion, incomplete abortion and complete abortion. There are also three special situations: missed abortion, habitual abortion, and abortion complicated by infection. Termination before 12 weeks of pregnancy is called early abortion, and termination between 12 weeks and less than 28 weeks of pregnancy is called late abortion. Abortion can be divided into spontaneous abortion and induced abortion, among which spontaneous abortion is mostly early abortion.
