The rate of preterm birth remains high and has no downward trend, despite the introduction of new technologies. Isthmic-cervical insufficiency is one of the most important causes of premature birth. At the same time, many issues related to the prediction and treatment of isthmic-cervical insufficiency remain open. There is now a sufficient number of studies showing the relationship between somatotype, course and outcome of the disease. At the same time, stu dies related to the study of somatotypes in obstetric pathology are not enough.
 The aim of the work is to assess the outcomes of pregnancy in women with isthmic-cervical insufficiency, taking into account the type of physique.
 Materials and methods. the course and outcomes of pregnancy in 164 women with cervical insufficiency were studied. A computer somatotropina by R.N. Dorokhov all the best for measured strength of the pelvic floor muscles using a device pelvic muscle trainer.
 Conclusions. The most frequently CI was found in women with mesosomatic and micro mesosomatic somatotype. Women macromesosomatic and micromesosomatic body types revealed low levels of muscle strength of the pelvic floor and a higher percentage of premature births. In groups macrosomy, macromesosomatic, microsomal body types often use different methods of correction CI. At the same time, the highest percentage of surgical correction of CI was observed in patients with macrosomatic type of physique. In other patients with different somatotypes, a non-surgical correction method was used.
