Abstract
People swim either for leisure or as professionals/occupation. Some stay in water (mostly marine water) for several minutes to hours each day. This may have an effect that may be ignored based on the understanding that the skin barrier prevents entry of foreign materials into the body. This research tends to find the effects of immersion of lower limb in marine water on testosterone secretion in adult male subjects. 33 male students from Nnamdi Azikiwe University College of Health Sciences were recruited for the study. Ethical clearance was obtained from the faculty ethical committee. The volunteers were divided into three groups (A[marine water], B[fresh water], C[distilled water]) and were asked to immerse their lower limb in different water type according to their group for one hour every day for fifteen days. Blood samples were collected (before and after immersion) from the volunteers intravenously on 1st, 5th, 10th and 15th day. The levels of testosterone were measured by ELISA methods. The mean difference of data collected before and after immersion was established. Data obtained were compared with control group using student T-test method, P<0.05. Those exposed to marine water showed a negative response in plasma testosterone concentration. There are significant difference in plasma testosterone level between group A and group C on Day0 and group A and group C on Day10. According to the result, it could be suggested that immersion of lower limb in marine water could attenuate testosterone secretion in adult males; the mechanism of action for this effect is poorly understood.
