AB Semen quality and levels of non-essential metals such as strontium (Sr), aluminum (Al), lead (Pb), nickel (Ni), and vanadium (V)were measured. Metals were determined by ICP-OES (inductively coupled plasma – optical emission spectrometry) in semensamples from 102 men who were recruited in a Reproduction Unit in the Canary Islands. The presence of each metal was asfollows: Sr: 56.9%, Al: 73.5%, Pb: 45.1%, Ni: 15.7%, and V: 79.4%of the samples. No significant differences were found in therelationship between the spermiogram, the sperm motility, and the concentration of spermatozoa levels of non-essential metals. Itis noteworthy that Ni levels tend to be lower in patients with oligozoospermia (t (46.4) = 1.84; p = 0.070). Between lifestyle andnon-essential metals, there was a significant relationship between the level of occupational exposure to metals and Ni (χ2(2) =13.91; p = 0.001). We did not find significant differences in non-essential seminal metal content and smoking status but, therewere differences between drinkers and the concentration ofV in semen (t (100) = −1.99; p = 0.050). The occupational exposure tometals and place of residence have effects on Al and V levels in semen. Regarding obesity, significant differences were found inPb levels (t (18.0) = 2.34; p = 0.031). Obese patients have a lower Pb level, and the percentage of progressive sperm motility waslower in obese men (t (98) = 2.14; p = 0.035). The detection of metals in semen opens a new field in the study of male infertilitywith the possibility of performing treatments aimed at correcting these possible anomalies.
