Causes of miscarriage

The main causes of miscarriage are associated with problems in the hormonal sphere of women, metabolic features and immune disorders.

In addition, infectious diseases, the anatomical abnormalities of the reproductive organs and various congenital diseases play an important role in the mechanism of the development of this pathology. Often, the reasons lie in the unhealthy image of a woman and her bad habits, as well as in bad ecology, which can lead to impaired development of the fetus.

At the same time, specialists admit that in almost half of cases of spontaneous termination of pregnancy, the true causes of miscarriage can not be clarified.

Paternal causes of miscarriage

Paternal causes of miscarriage are less important than maternal ones, except for chromosomal pathology. Nevertheless, according to many researchers, the husbands of women with habitual miscarriage have a high percentage of spermatogenesis disorders: oligospermia, polyspermia, teratospermia and leukocytospermia.

Extragenital diseases of the mother and premature termination of pregnancy

Extragenital diseases of the mother are one of the frequent causes of premature termination of pregnancy. The group of high risk for miscarriage is primarily women with diseases of the cardiovascular system, hypertension, chronic kidney disease, liver, intestines.

Factors of abortion

Among the factors of abortion, complications of pregnancy take a big place: gestations of the second half of pregnancy, anomalies of placenta attachment, premature detachment of the placenta, improper position of the fetus.

Pathology of the uterus as a reason for habitual miscarriage

A major role in the etiology of habitual miscarriage is played by malformations of the uterus, especially in the termination of pregnancy of the second and third trimesters. The incidence of malformations of the uterus in the population is only 0.5-0.6%.

Violation of the system of hemostasis and miscarriage of pregnancy

The state of the hemostatic system determines the course and outcome of pregnancy for the mother and fetus. In recent years, there has been a significant number of publications pointing to the great role of thrombophilic complications in habitual miscarriage, fetal death, placental abruption, eclampsia development, intrauterine growth retardation.

Antiphospholipid syndrome and miscarriage

Antiphospholipid syndrome is the most common cause of thrombophilic complications and associated habitual pregnancy loss. There are primary antiphospholipid syndrome and secondary - if there is also an autoimmune disease (most often it is systemic lupus erythematosus).

Immunological causes of miscarriage

For several decades, with the emergence of new methodological possibilities in immunology, the problem of immunological relationships between the mother and the fetus is given the closest attention.

Bacterial causes of miscarriage

In recent years, work has appeared that shows the role of disturbances in the normal microflora of the genital tract in the premature termination of pregnancy.

Coxsackie-viral infection and miscarriage

The high risk of vertical transmission of enteroviruses, mainly Coxsackie viruses, was established in the presence of spontaneous miscarriages, stillbirths and complications such as the threat of termination of pregnancy.

Herpes and habitual miscarriage of pregnancy

Genital herpes is one of the most frequent human infections. Most researchers believe that the true frequency of the herpes simplex virus in women is not known, since the share of assimptomatic forms and virus carrying is high.
