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.

Herpes and habitual non-pregnancy

Genital herpes is one of the most common human infections. Most researchers believe that the true incidence of herpes simplex virus in women is unknown, as the proportion of asymptomatic forms and virus carriage is high.

Cytomegalovirus infection with habitual non-pregnancy

Intrauterine infection with cytomegalovirus infection is the most common among other infections and occurs in 0.4-2.3% (on average 1%) of all newborns, although this figure varies significantly among different populations.

Infectious causes of non-pregnancy

The question of the etiological role of infection is widely discussed in the literature. Some researchers believe that infection is one of the most significant causes of miscarriage, both sporadic and habitual, while others believe that infection may play a role in sporadic miscarriage, but not in habitual miscarriage.

Hyperprolactinemia as a cause of pregnancy failure

According to many researchers, hyperprolactinemia causes infertility precisely because of its effect on steroidogenesis and excess androgens, but if pregnancy occurs, its course, as a rule, proceeds without significant complications.

Hyperandrogenism as a cause of pregnancy failure

Among the hormonal disorders that lead to miscarriage, hyperandrogenism occupies a very important place - a pathological condition caused by changes in the secretion and metabolism of androgens.

Endocrine causes of non-pregnancy

Just 20 years ago, we believed that the most common cause of miscarriage was endocrine disorders in the mother’s body, and the most common cause was ovarian hypofunction.

Genetic causes of miscarriage

In connection with the use of genetic research methods, significant opportunities have emerged for expanding our understanding of the genesis of spontaneous abortions.

Socio-biological factors of non-pregnancy

Socio-biological factors significantly influence the course of pregnancy and therefore can be associated with miscarriage. Many researchers associate miscarriage with place of residence.

Causes of non-pregnancy: genetic, endocrine

There is currently no comprehensive classification of the causes of miscarriage. Apparently, this is due to the fact that it is difficult to bring together into a single system all the variety of reasons leading to termination of pregnancy.
