Presence of gold in semen.

6. We have established Atomic Absorption Spectrophotometry as the most suitable method for estimation of gold in semen. For this, some samples were estimated by using Neutron Activation, Polarography and Atomic Absorption Spectrophotometry (7). Gold is present in sea water where life ong1nated. So its presence in present forms of life is not surprising. The total amount of gold present in an adult human body is <1mg (2). This amount is more than what is present in same weight of sea water (13). We also know that certain substances are more concentrated in semen than in blood. The metal zinc is the best example (LK Kothari, personal communication; 5,9). The gold may be entering the semen through· caput epididymis and testis as supported by our studies employing mass emission spectroscope (8) and histochemistry techniques (12). In the latter studies, gold was not detected in vital organs, but was seen in kidney and liver only after the treatment with gold.
