Presence of several elements in normal and pathological human semen samples and its origin.

Spectroscopic analysis of seventeen normal and pathological semen samples was done to reveal the different elements present in it. The sensitivity of the instrument was 1 micrograms/g. The observed elements include sodium, potassium, magnesium, calcium, phosphorus, iron, manganese, zinc, copper, boron, silicon, thallium, vanadium, aluminium, mercury and gold. This is the richest source of gold reported in biological materials. An attempt was done to locate the origin of these elements. Thus gold is released from caput epididymis.
