Abstract
Habitual pregnancy miscarriage is one of the serious problems of reproductive health in the modern world. Habitual miscarriage is defined as the spontaneous termination of two or more pregnancies before the fetus reaches viability from conception to 24 weeks of pregnancy. However, some differences of opinion are determined among specialists in habitual miscarriage. Some experts in their clinical practice for habitual miscarriages use the definition of three or more consecutive miscarriages. Habitual miscarriage occurrence varies from 0.5 to 2.3%, but the exact prevalence is very difficult to estimate, which depends on the used definition. The pathogenesis of habitual miscarriage is determined based on the age of the mother and the gestational age of the fetus. Habitual miscarriage can be caused by chromosomal errors, autoimmune disorders, endometrial dysfunction, endocrinopathies, hormonal and metabolic disorders, infections, and uterine anatomical defects. Currently available treatments target suspected risk factors for miscarriage, although the effectiveness of many medical interventions appears to be controversial.
This study aimed to evaluate the effectiveness of treatments for habitual miscarriage of various origins, such as antiphospholipid syndrome, subclinical hypothyroidism, and idiopathic habitual miscarriage.
