A few years ago, I was pregnant for more than a month and then had an automatic abortion. However, after a series of maintenance and treatment, everything is very good now. Today I would like to share with you what causes threatened abortion, which you all want to know.

What causes threatened abortion

First, chromosomal abnormalities, including husband and wife chromosomal abnormalities and embryo chromosomal abnormalities. The common chromosomal abnormalities in couples are balanced translocation, Robertsonian translocation and so on. Triploid was the most common chromosome abnormality, followed by polyploid, x-monomer, autosomal monomer, balanced translocation, deletion, chimerism, inversion and overlap. The incidence of chromosomal abnormalities in couples with recurrent abortion was 4%, while that in normal population was 0. The ratio of mother to father is 3:1. The main cause of single spontaneous abortion was chromosome abnormality. With the increase of abortion times, the incidence of chromosome abnormality decreased.

(1) corpus luteum dysfunction accounts for 23% - 60%, the basal body temperature is biphasic, but the high temperature phase is less than 11 days, or the temperature difference between high and low is less than 0. Endometrial biopsy showed that the secretory reaction was at least 2 days behind. Progesterone in luteal phase was lower than 15ng / ml, which caused adverse decidual reaction. The diagnosis could be included only if the luteal function test in 2-3 cycles was insufficient. Luteal insufficiency affected the implantation of pregnant eggs. 2) High concentrations of luteinizing hormone, hyperandrogen and hyperinsulinemia in polycystic ovary syndrome reduce egg quality and endometrial receptivity, which can easily lead to abortion.

Third: genital tract infection, bacterial vaginosis in patients with late pregnancy abortion and premature birth increased, Chlamydia trachomatis, Ureaplasma urealyticum caused by Endometritis or cervicitis can cause abortion.
