DEL BALZO, Diego Damián et al. Relationship between plasma oestradiol, fasting glucose, and triglycerides in males with metabolic syndrome. Rev. argent. endocrinol. metab. [online]. 2016, vol.53, n.3, pp.90-95. ISSN 1851-3034.

Introduction: Oestradiol circulates in low concentrations (8-40 pg/ml) in males, with its functions still not being entirely clear. In this context, there is a need to determine the effects it has on males. Apart from studying the potential role oestradiol has on male reproduction in recent years, efforts have been made to determine the relationship between oestradiol levels and metabolic syndrome components. Nevertheless, the existing bibliography does not clarify whether oestradiol plays a protective or detrimental role in this condition. Objectives: The present work aimed to analyse the relationship between serum oestradiol levels and metabolic syndrome components in overweight men from Mendoza. Methodology: The sample consisted of 40 overweight or obese males, aged 53-74, with metabolic syndrome, and living in the city of Mendoza. Based on a health routine check-up, they were evaluated by determining the levels of oestradiol, testosterone, fasting blood glucose, insulin, HOMA index, lipid profile, and uric acid. Nutritional status was assessed using anthropometric measurements: weight, height, circumferences, and skinfold thickness. Statistical analysis was carried out using Pearson or Spearman correlation according to the normality of variables and the Student t test for independent samples. A minimum level of significance of P<.05 was used. Results: Oestradiol levels negatively correlated with triglyceride values (r = -0.401; P=.013) and fasting blood glucose (r= -0.333; P=.041). Furthermore, those with normal triglycerides (triglyceride values <150 mg/dl) showed higher oestradiol levels compared to those with high triglycerides (P=.02). Conclusions: Oestradiol levels show an inverse relationship as regards triglycerides and fasting blood glucose in men with metabolic syndrome.
