Heavy Metal Levels in Males With Idiopathic Hypogonadotropic Hypogonadism.

INTRODUCTION: The toxic effects of heavy metals on biological systems are being investigated with increasing interest day by day. Our purpose was to investigate heavy metals such as aluminum (Al), cadmium (Cd), arsenic (As), lead (Pb), and nickel (Ni) in males with idiopathic hypogonadotropic hypogonadism (IHH) and to determine whether there is a relationship between heavy metals and testosterone levels.

METHODS: Twenty-six male patients with IHH aged 18-50 and 22 healthy males aged 21-50 admitted to the Outpatient Department of Endocrinology for follow-up were enrolled. BMIs were calculated by measuring the height and weight of all participants. Al, Cd, As, Pb, and Ni levels were measured and compared between groups. Testosterone levels were measured to investigate whether there was a correlation with heavy metal levels.

RESULTS: Al, Cd, As, Pb, and Ni levels were statistically higher in the patient group compared to the control group (p<0.001). A moderately strong significant negative correlation was detected between the patients' testosterone and As levels (p=0.001, r=-0.609, R2 =0.371). Decreased As and Cd levels were observed as the patients' ages increased (p=0.013, r=-0.471).

CONCLUSION: Heavy metals might play potential roles in IHH. We hope that investigating heavy metal levels in IHH and adding toxicity-preventive treatments to hormonal therapies will be beneficial in the multifaceted management of the disease in clinical practice.
