What is spontaneous miscarriage?
A miscarriage is terminated when the pregnancy is less than 28 weeks or the fetus weighs less than 1000g. If the pregnancy is terminated by artificial factors such as surgery or medication, it is considered an induced abortion; while a miscarriage caused by natural factors is called a spontaneous abortion.
What should I do if I have had 1 spontaneous abortion in the past?
There is a 20% chance of spontaneous abortion for normal couples. Couples with only one history of spontaneous abortion do not need to be nervous, but are advised to use contraception for 6 months and prepare for pregnancy again after a preconception health check. If you are pregnant, it is better to have an early check-up and if necessary, to have a fertility treatment.
What should I do if I have had 2-3 spontaneous miscarriages in the past?
Those who have had 2 or more consecutive spontaneous miscarriages are called habitual miscarriages or recurrent miscarriages. In this case, both spouses should be examined for the cause of spontaneous miscarriage and treated for the cause to avoid another miscarriage.
What is recurrent miscarriage?
Recurrent miscarriage is traditionally defined as three or more consecutive spontaneous abortions. However, several recent studies have pointed out that the risk of recurrent miscarriage after 2 consecutive miscarriages is similar to the risk of recurrent miscarriage after 3 consecutive miscarriages. Therefore, couples with 2 or more consecutive spontaneous miscarriages should be evaluated to determine the cause of the miscarriage.
What causes recurrent miscarriage?
There are many factors that can cause recurrent miscarriage, including anatomic, endocrine, heritage, infectious, and immunological factors. Others include male factor, maternal combined medical disease, poor lifestyle habits and environmental factors. If the cause cannot be detected by current medical methods, it is called recurrent miscarriage of unknown origin.
How to treat and prevent recurrent miscarriage?
If the cause of recurrent miscarriage is found, pregnancy can be treated for the cause; if there is no clear cause, recurrent miscarriage of unknown origin can be treated with lymphocyte immunotherapy by the husband before pregnancy. If pregnancy is planned, it is recommended to monitor ovulation by vaginal ultrasound, estimate the time of ovulation and guide intercourse, and start treatment such as luteal support immediately after ovulation.
What are the causes of recurrent miscarriage screening?
1, anatomical abnormalities of the reproductive tract: ultrasound, hysterosalpingography or hysteroscopy to exclude endometrial polyps, submucosal fibroids, saddle-shaped uterus, longitudinal uterus, and double uterus;
2.Endocrine examination: sex hormone six, luteal progesterone, thyroid function, oral glucose tolerance and insulin release test;
3, genetic examination: karyotype examination of both spouses, karyotype examination of aborted embryos;
4.Infection factor examination: virus (toxoplasmosis, rubella, herpes) examination, cervical chlamydia, gonococcal examination;
5.Immunity factor examination: blood group of both spouses (ABO and RH blood group), reproductive immune antibody (anti-endometrial antibody, anti-cardiolipin antibody, anti-sperm antibody, etc.);
6, the male partner semen routine and malformation rate check, if necessary, check the male partner sperm DNA integrity.
Is spontaneous abortion related to age?
The rate of miscarriage is 14% at the age of 25, but rises to 44.5% at the age of 35 and up to 50% at the age of 45. This is because: as we age, the likelihood of chromosomal aberrations in the egg cells increases, followed by an increase in the rate of chromosomal abnormalities in the embryo, leading to natural elimination.
