The incidence and aggravating factors of male hypogonadism in type 2 diabetes

Abstract

BACKGROUND: Male hypogonadism is associated with type 2 diabetes mellitus (T2DM), therefore, it is of interest to study its frequency. The clinical symptoms of hypogonadism are not specific, and laboratory diagnostics is the basis for its detection. The optimal method for this diagnostics is isotope dilution liquid chromatography/tandem mass spectrometry, which was used in our study. AIMS: Assessment of the incidence and aggravating factors of male hypogonadism in type 2 diabetesMATERIALS AND METHODS: A full-design, cross-sectional, screening, single-center, non-interventional study included men with T2DM, who were he was treated in Endocrinology Research Centre, Moscow. The study was conducted from October 2021 to January 2022. Medical history assessment, physical examination with determination of body mass index (BMI), measurement estimation of total testosterone by isotope dilution liquid chromatography/tandem mass spectrometry, glycated hemoglobin (HbA1c) and lipid profiles were performed. The groups were compared using the Mann-Whitney U-test for quantitative indicators and χ² with Yates’ correction for qualitative ones. Differences were considered statistically significant with p0,05.RESULTS: Hypogonadism was detected in 355 (70.3%) men with T2DM. Patients with hypogonadism had statistically significantly higher BMI, worse glycemic control, lower HDL levels, and higher triglycerides than eugonadal men. An additional comparative analysis among non-obese individuals showed the presence of statistically significant differences in the level of HbA1c (higher in hypogonadal men) and HDL (lower in hypogonadal men). An analysis of hypogonadal patients depending on the presence of obesity showed statistically significant differences between groups in the level of total testosterone (lower in obese men) and triglycerides (higher in obese men).CONCLUSIONS: The prevalence of male hypogonadism in type 2 diabetes was 70,3%. Its development was associated with obesity and poor glycemic control.
