AIMS: Male hypogonadism is highly prevalent among patients undergoing dialysis and carries significant clinical implications, although is often overlooked. Testosterone deficiency in this population is associated with adverse clinical outcomes, mainly because of cardiovascular disease, protein energy wasting and infection complication. Therefore, identify these patients is a high clinical priority. METHODS: This is a cross-sectional study that enrolled adult men on maintenance hemodiafiltration in four dialysis centers. Hypogonadism was defined by two consecutive measurements of serum total testosterone levels. Free testosterone was calculated based on serum albumin and sex hormone-binding globulin. Symptoms of androgen deficiency were evaluated using androgen deficiency in aging males (ADAM) questionnaire. The presence of comorbidities and laboratory markers was also evaluated. RESULTS: Hypogonadism was identified in 59 out of 121 patients (48.7%). Patients with hypogonadism were older (62 ± 15 vs. 57 ± 15 years, p < 0.001) and had higher prolactin levels (22 [13-36] vs. 14 [10-18] ng/mL, p = 0.002). No other significant difference was observed in demographic, clinical, or laboratory features between patients with and without hypogonadism. Among the 16 patients who received testosterone supplementation, 66.7% showed improvement in ADAM scores, with the median score decreasing from 3 (2-4) to 1 (0-2) (p = 0.003). CONCLUSION: More than one-third of men undergoing hemodiafil...
