Hypogonadism and subnormal total testosterone levels in men with type 2 diabetes mellitus
College of Physicians and Surgeons Pakistan
Objective: To determine the frequency of testosterone deficiency syndrome (TDS) in men with type 2 (DM). Study Design: A cross-sectional study. Place and Duration of Study: The Gbagada General Hospital, Gbagada Lagos, Nigeria, from December 2009 to May 2010. Methodology: A total of 203 men with type 2 DM aged 30-86 years were evaluated for TDS by a combination of positive ADAM (androgen deficiency in the ageing male) scores and subnormal total testosterone levels. Mild testosterone deficiency referred to total testosterone (TT) levels of 8-12 nmol/L with symptoms of hypogonadism and severe testosterone deficiency referred to TT levels < 8 nmol/L with or without hypogonadal symptoms. Results: Mild and severe TDS were present in 18.3% and 17% respectively of the study subjects. Commonly occurring clinical parameters of the TDS were erectile dysfunction and loss of libido which were documented in 63% and 60% respectively in the study subjects. The majority of clinical features of the TDS were comparable in men with and without the TDS. Conclusion: About a third of men with type 2 DM had the TDS. The majority of the symptoms of hypogonadism are largely non-specific and their occurrence is comparable in men with and without low testosterone levels; thus, underscoring the need to have testosterone levels determined in men presenting with such symptoms.
