Will having sex cause miscarriage?

If a female friend successfully becomes pregnant, it is best not to have sex, because sex may affect the normal development of the fetus, especially in the early and late stages of pregnancy. In the early stages of pregnancy, having sex can easily cause miscarriage, but having sex in the middle stages of pregnancy will not cause fetal arrest, and it is also a stage that will not affect the development of the fetus. Therefore, it is recommended that couples do not have sex during pregnancy to avoid miscarriage.

Will having sex in early pregnancy cause the fetus to stop growing?

When you are 8 weeks pregnant, you are already more than two months pregnant, and this is still the early stage of pregnancy. The early stages of pregnancy are when the fetus is most likely to have problems, and there are many possible problems, such as miscarriage, fetal arrest, etc.

Clinically, the common causes of fetal arrest in three months of pregnancy are as follows.

1. Chromosomal abnormality: Whether it is sperm or egg, as long as the chromosomes carrying genetic material are abnormal, even if a fertilized egg is formed, the embryo will not develop normally. Therefore, if there is a history of genetic disease in the family, a medical diagnosis and pre-pregnancy physical examination should be conducted before pregnancy.

2. Uterine abnormality: The overall environment in the uterus is not good, which will affect the development of the embryo. Data show that miscarriages caused by uterine defects account for about 10%-15% of clinical cases, and fetal arrest accounts for about 10%.

3. Placental factors: Placental abruption, placenta previa, etc. can all lead to insufficient oxygen supply to the placenta, causing fetal hypoxia and fetal arrest.

4. The pregnant woman herself has chronic diseases: Pregnant women have serious chronic diseases, such as diabetes, hypertension, heart disease, viral hepatitis, etc., and long-term medication will affect the life and health of the fetus.

Causes of fetal arrest

1. Luteal insufficiency

The corpus luteum of the ovary secretes estrogen and progesterone to maintain pregnancy. The placenta replaces the function of the corpus luteum after 10 weeks of pregnancy, and the corpus luteum maintains the pregnancy until 3-4 months of pregnancy before beginning to shrink. Progesterone is the progestogen that maintains pregnancy, and luteal insufficiency can easily lead to fetal arrest.

2. Abnormal fertilized egg

If one of the parents' sperm or egg is defective, an abnormal fertilized egg will be formed. Abnormally fertilized eggs do not develop maturely in the uterus, and most of them will end up in early fetal arrest, which is a natural reproductive selection.

3. Maternal disease

Adverse factors that affect fetal development, such as reproductive organ diseases and severe uterine malformations, can also cause fetal arrest. Some fetal arrests are caused by acute or chronic diseases such as influenza, hepatitis, and severe anemia. Edema is likely to occur in the 6th month, leading to gestational hypertension. Pregnancy-induced hypertension can cause fetal hypoxia and suffocation.

4. Premature rupture of membranes

If the fetal membrane ruptures before delivery, vaginal discharge will occur. After the fetal membrane ruptures, the fetus loses the protection of the amniotic membrane, the chance of infection increases, and the umbilical cord is prone to falling off, causing fetal death. Sexual intercourse is strictly prohibited in the 10th month of pregnancy to avoid premature rupture of membranes and premature birth.

4. Environmental factors

In the early stages of pregnancy, chemical components of various detergents are absorbed through the skin and accumulate in the body, which can induce fetal arrest. The early embryo is very sensitive to radiation, toxic chemicals and viral infections and should be avoided. Harmful substances such as nicotine can cause sperm to become underdeveloped, deformed or defective, and increase the incidence of fetal growth retardation. Noise can cause endocrine disorders in pregnant women, induce uterine contractions and cause miscarriage.
