In the case of an undeveloped pregnancy, a genetic factor can play a role (if the embryo is formed with an excessive number of chromosomes). The causes of such a chromosomal abnormality can be chronic mother stress, smoking, drug use, adverse ecology, etc. When a genetically inferior embryo is formed, according to the laws of natural selection the mother's organism tries to get rid of it - and there is an undeveloped pregnancy.
Intrauterine death of the embryo can be caused by infection, either acute or chronic, viral or bacterial. Infection of the fruit egg occurs for three reasons:
- with a chronic inflammatory process of the mucous membrane of the uterine cavity;
- for bacterial vaginosis, fungal vaginal infection and other inflammations;
- Even with normal ORZ, germs with blood flow can penetrate the placental barrier.
If infection occurs in the early stages of pregnancy, the embryo stops developing and dies.
There are endocrine factors affecting an undeveloped pregnancy. This is an increased number of male sex hormones or a hormone that stimulates milk production, a violation of thyroid function, obesity or lack of body weight. With any endocrine pathology, there is a deficiency in the ovary of a substance that produces a hormone that prepares the body of a woman for the onset of pregnancy. With its deficiency, the embryo does not receive enough nutrients from the mother's blood and dies.
Diagnosis of an undeveloped pregnancy is possible with a dynamic observation of the growth of the uterus. Clarification of the diagnosis is carried out using ultrasound. Clear manifestations such as pain and discharge may not be. If the diagnosis is confirmed, then hospitalization and termination of pregnancy is necessary, since there is a danger to a woman's life because of possible infectious complications and bleeding. When scraping, it is advisable to take samples of the embryo tissue for examination in order to clarify the cause of the undeveloped pregnancy and, if necessary, to conduct anti-inflammatory therapy. In the future it will be necessary to prepare for subsequent pregnancies, which can be planned no earlier than 6 months after scraping.
