Features of somatometric and genitometric parameters of young men of the republic sakha (yakutia)

The study of the relationship of a number of somatometric parameters with the characteristics of the reproductive functions of men is an urgent problem of modern andrology and reproductive medicine. The purpose of the study was to establish the reference values of genitometric parameters in young men living in the Republic of Sakha (Yakutia) and the features of their relationship with somatometric parameters as conjugate predictors of reproductive functions. The survey involved adult boys of indigenous nationality aged 18-20 years, permanently residing in the Republic of Sakha (Yakutia), a total of 74 people. Anthropometric measurements included measurements of total body size and weight, body composition by bio-impedancemetry. Ultrasound examination of the scrotum was performed on a portable ultrasound sonograph «Mindray M7» using a linear transducer with a frequency of 7,5 MHz. Ultrasound scanning of testicles was made in three projections, of testicles appendages - in two projections. Testicular volume in ml was calculated using Brown's (1981) formula. Statistically significant differences in anthropometry and bio-impedancemetry data in two groups of young men with normal and elevated body mass index values are shown. The average value of the body mass index of young men was 22,09±0,82. Normal body weight was determined in 78,2% of young men, overweight - in 21,8%, cases of obesity and underweight were not detected. The most variable are the length of the right testicle (4,29±0,14 cm), the most stable and independently varying are the latitudinal dimensions of the testicles (the thickness of the left testicle was 2,18±0,05 cm). Bilateral differences in the size of the testicles were established, the parameters of the right testicle significantly exceed those of the left testicle. A statistically significant correlation is inherent in the average volume of the testicles with the phase angle, moderate - with indicators of active cell mass and skeletal muscle mass. The data obtained can be used as reference values in clinical practice to assess development and compliance with age norms and in the diagnosis of disorders of physical development and the reproductive system.
