why is gold forbidden for men in islam? an original study

background and objectives according to islamic doctrines, the use of gold for men has been banned. in general, any advised subject in islam is useful for the body and what has definitely forbidden for a man is definitely harmful for him although its reasons have not been exactly specified. however, muslims believe that there is certainly a sound reason behind this prohibition. this issue was studied in vitro on fertile men in the city of babol by means of gold nano particles. materials and methods: a total seminal fluid from 20 healthy individual volunteers from the city of babol whose fertility had been approved was examined for the gold content through atomic absorption at the wavelength of 242.8nm with hollow gold cathode lamp. prior to analyzing all the collected samples, they were put into a mixture of thick citrate and per chloric acids at a ratio of 1 to 6. findings: in the samples studied, the amount of gold in the semen was found to be in the range of 0.32 to 1.92 µg/ml with a mean value 0.89 µg/ml and the standard deviation of 0.61µg/ml. conclusion: in the present study, the existing gold in the full seminal fluid was estimated after complete digestion. (oxidation of organic materials; so the amount of  identified gold and the  plasma levels of semen were separated like  sperm). therefore, the hypothesis of the presence of gold in sperm seems to be true. due to the scarcity of articles in this regard and the previous studies, it seems that more studies are needed in order to shed light on the role of the gold on men's fertility. from the viewpoint of islam, this study proved the presence of gold in seminal fluid. in addition, the decrease in sperm movement after the influx of gold shows the forbiddance of old for men.
