Abstract: FIELD: medicine. 
     SUBSTANCE: method involves distinguishing four degrees in sexual development delay. Minimum sexual development delay degree is characterized by the following parameters. Uterus width and thickness corresponds to age-specific norm. Median uterine M-echo is recorded. Uterus neck is differentiated from uterus body with angle between them being well distinguished. All ovarian dimensions correspond to norm. Light sexual development delay degree is characterized as follows. All uterine dimensions are two years smaller, when compared to age-specific norm. Median uterine M-echo is recorded. Uterus neck is differentiated from the uterus body. Ovary length and thickness correspond to age-specific norm. Moderate sexual development delay degree is characterized as follows. All uterine dimensions are three-four years smaller, when compared to age-specific norm. Median uterine M-echo and reduced ovary length and thickness are recorded. Severe sexual development delay degree is characterized as follows. All uterine dimensions are six-eight years smaller, when compared to age-specific norm. No uterus neck is differentiation from the uterus body is available. No median uterine M-echo is recorded. Ratio coefficient of length and anteroposterior dimension of uterine body to length and anteroposterior dimension of uterus neck is additionally determined in each sexual development delay degree case. Uterine blood vessel lumen, ovary echostructure as number, diameter of minimum and maximum follicles in them are determined in energetic Doppler mapping mode. Uterus length having 1-2 years delay when compared to norm, ratio coefficient of uterus and neck dimensions being equal to 1.5-1.7, uterine blood vessel lumen being equal to 5-6 mm, follicle number being in norm, diameter of minimum and maximum follicles having 1-2 years delay when compared to age-specific norm, minimum sexual development delay degree is diagnosed (IA). Uterine blood vessel lumen being equal to 4-5 mm, coefficient of uterus and neck dimensions being equal to 1.3-1.5, follicle number being in norm, ovary width having 1-2 years delay when compared to norm, minimum follicles having 2 years delay when compared to age-specific norm, maximum follicles having 2-3 years delay, light sexual development delay degree is diagnosed (IB). All uterine dimensions being three-four years smaller, when compared to age-specific norm, uterus neck being differentiated from uterus body with angle between them being poorly distinguished, uterine blood vessel lumen being equal to 2-3 mm, ratio coefficient of uterus and neck dimensions being equal to 1.2-1.5, reduced follicle number having 1-2 years delay when compared to age-specific norm, ovary width having 2-3 years delay when compared to norm, minimum follicles diameter having 2 years delay when compared to age-specific norm, maximum follicles diameter having 2-3 years delay, moderate sexual development delay degree is diagnosed (II). Uterine blood vessel lumen diameter being equal to 1 mm, ovaries dimensions delay being of 2-3 years with lacking follicular apparatus in them, severe sexual development delay degree is diagnosed (III). 
     EFFECT: high accuracy and self-descriptiveness of the method.
