Xiao Zhong and Xiao Zhu are my neighbors and have just been married for a year. Recently, the young couple seemed very happy. Xiao Zhong quietly told me that his wife was three months pregnant. When you are about to become a parent, you are naturally very happy and happy. However, two days ago, Xiao Zhong accompanied his wife to the hospital to see me, with a sad look on his face. It turned out that his wife had noticed a small amount of light coffee-like vaginal bleeding in the past two days. Although she was not particularly uncomfortable, she was worried that something might be wrong with the child in her belly. So, I asked Xiao Zhu to have an obstetrics and gynecology B-ultrasound examination first. It was found that the size of the gestational sac in her uterus was significantly smaller than the normal gestational size, and the gestational sac had been deformed and irregular. The heart tube pulse of the embryo was found, and B-ultrasound diagnosed it as threatened abortion. When the B-ultrasound doctor told them that it might be difficult to save the child, Xiao Zhu couldn't help crying sadly.

Looking at the sad and sobbing Xiao Zhu and the worried Xiao Zhong, I comforted them and said, "Actually, you don't have to be too sad, because miscarriage is not necessarily a bad thing." After hearing this, they At the same time, he turned his face towards me with a puzzled expression. So, I explained to them both. I told them that since you are still young, it is entirely possible for you to become pregnant again in the future. The wisest solution for you is to go to the obstetrics and gynecology department for dilation and curettage. You would rather terminate the pregnancy than just preserve the fetus. This is because a situation like Xiao Zhu’s is a natural miscarriage, which has many causes. Abnormal development of the pregnant egg or embryo may be the main factor. According to surveys, more than 70% of embryos that are spontaneously aborted within the first three months of pregnancy have abnormal morphology. Abnormalities in pregnant eggs may be caused by defects in sperm and eggs, including abnormalities in the number and structure of their chromosomes. In other words, the vast majority of sick fetuses are eliminated naturally through abortion. So in a sense, abortion is a natural selection of survival of the fittest.

If active fetal protection measures are taken for such spontaneously aborted embryos, it is possible to give birth to a malformed fetus or a child with delayed intellectual development in the future. From a eugenic perspective, this approach is not advisable, especially For young couples. Progesterone injections are often given for miscarriage treatment in order to inhibit uterine atrophy, promote decidua growth, and facilitate embryonic development. However, there are reports that using progesterone in early pregnancy can increase the risk of heart defects in the fetus, especially for female babies. It can also cause virilization of the genitals and pseudohermaphroditism. Therefore, tocolytics may also be teratogenic.

After listening to my explanation, Xiao Zhu stopped sobbing and regained his composure. The couple finally decided to go to the obstetrics and gynecology department for a dilation and curettage two days later.
