The Relationship Between Cadmium Levels and Testosterone Levels in a Sample of Aleppo City Residents

Abstract

This study aimed to determine the blood concentration levels of cadmium in a sample of residents of Aleppo and to correlate them with their testosterone concentration levels. The experiment was conducted using 75 participants divided into 3 groups, averaging 25 participants per group: a group of people who work with electrical generators, a group of smokers, and a control group. The results showed higher average cadmium concentration levels in all groups, including the control group, compared with the normal levels of cadmium concentration in the body. The average concentration levels per group were 88.48 µg/l, 82.32 µg/l, and 19.84 µg/l, respectively. The results also showed lower mean testosterone concentrations in both the group of people who work with electrical generators (5.53 ng/ml) and the group of smokers (4.43 ng/ml) when compared with the control group (7.59 ng/ml). Using the Pearson correlation coefficient, a correlation was found between cadmium concentrations and testosterone concentrations (P = 0.05).
