There were used the ultrasound estimation of cervical echogenity (grey scale) with simultaneous histogramms in 6 standard zones with equal squares, each of them was placed in central parts of external os, middle third of cervix and region of internal os. Received information after computer analysis allowed to get objective information about tissue echogenity in examined zones. In parallel the metric characteristics of cervix and its estimation by means of Bishop scale were done. It was established that echographic structure of cervical tissue reflects morpholological changes and maturity. This method gives a possibility to differ as minimum three echotypes of cervix hyper-, poly-, and hypoechogenic, in accordance with conception of поп-mature, maturing and mature cervix. It was confirmed by labor and delivery outcomes analysis. The metric characterisics and Bishop scale do not give objective characteristics of cervical maturity
