The fetal abortion is a form of spontaneous miscarriage, which can be manifested by ultrasound examination: fetal buds or fetuses in the gestational sac are irregular, no fetal heartbeat, or an empty sac. In recent years, with the accelerated urbanization, air pollution, food safety situation is serious, life pressure increases, more and more patients with fetal abortion, some couples even experienced three or four times fetal abortion, this part of the couple next pregnancy is often “all the time”, “like walking on thin ice These couples are often “scared” and “on thin ice” after their next pregnancy, and are under unimaginable mental stress. When we feel horrible about something, the reason may be that we don’t know the truth. The causes of fetal abortion can be divided into three types: female causes; male causes; and both male and female causes. In reality we pay more attention to the female factor, but less attention to the male cause. In general, we think that as long as the wife can get pregnant, the husband must be fine, and once the wife gets pregnant, the husband’s “responsibility” ends. It is easy to imagine that there are many, many people who think this way. People who grew up in the countryside know that once the crop in the ground grows badly, farmers will not only suspect the purchase of fake fertilizer, but also suspect that the seeds may be false, the “responsibility” of good seeds not only grow from the ground, and must grow well, how the crop grows seeds are to be “responsible for The “responsibility” of good seeds is not only to grow from the ground, but also to grow well, and the seeds are responsible for how the crop grows. The reason for this is that the male factor should never be overlooked and semen routine is an important test. The cycle of sperm is about three months, six months before the examination is normal, may be six months after the pregnancy again when the semen is not normal.
