Owing to hypoplasia or premature degeneration of corpus luteum, inadequate progesterone secretion, or delayed or stagnated endometrial development in secretory phase caused by decreased endometrial responsiveness to progesterone, or asynchrony of matrix and gland development, which affects the implantation of pregnant eggs.

2. Chromosome abnormalities

If the chromosome abnormalities of both spouses or one or the other of the embryos lead to the abnormal development of the embryos, spontaneous abortion often occurs, because some embryos have abnormal chromosomes of their parents. Chromosome abnormalities should be judged according to the types of abnormalities, and prenatal diagnosis should be made to ensure good birth and fertility.

I. Early symptoms

1. A little vaginal bleeding

Women with early symptoms of habitual abortion and general abortion are the same, their vaginal bleeding may continue for several days, or may continue for several weeks, but the blood volume is generally less. If female friends have more blood, it means that women will have abortion, and can not avoid the occurrence of abortion.

When a female friend discharges a part of the pregnancy in the uterus, it is called incomplete abortion that part of the pregnancy remains in the uterus; if the pregnancy in the uterus is totally excreted from the female body, then it is called complete abortion. When this happens, women should go to the hospital in time to do the corresponding uterine clearance, so as to avoid the pregnancy in the body triggering the female. Sexual infection occurs.

2. Late symptoms of habitual abortion

Increased vaginal bleeding and abdominal pain: when the cervix is examined, dilatation can be found, or the foetal sac is blocked at the cervical orifice, then habitual abortion will inevitably occur.
