Hyperestrogenism and low serum testosterone-17β-estradiol ratio are associated with non-bacterial male accessory gland inflammation.

This study evaluated the serum concentrations of the main sex hormones in selected patients with non-bacterial male accessory gland infection (MAGI). The results suggest that the mean serum concentrations of 17β-estradiol (method : chemiluminescence) in these patients are significantly higher compared to the controls (55.0 ± 15.0 vs. 26.5 ± 12.0 pg/mL; P <0.05) and the percentage of patients with MAGI and associated hyperestrogenism (according to the laboratory range used in this study) was significantly higher (25.00% vs. 3.00%; P <0.05). Moreover, the percentage of patients with non-bacterial MAGI and associated testosterone deficiency (serum total testosterone <2.49 ng/mL) was significantly higher (18.00% vs. 2.00%; P <0.05). Finally, patients with non-bacterial MAGI showed a significantly lower total testosterone-17β-estradiol ratio compared to the controls (72.7 vs. 173.0; P <0.05). The results of this study, with some limitations (in particular the method applied for the determination of serum concentrations of 17β-estradiol) represent in our opinion, a topic worthy of further investigation for a correct endocrinological characterization of these patients, useful for clinical practice.
