Lead and cadmium concentration in the seminal plasma of men in the general population: correlation with sperm quality.
The concentration of lead and cadmium in the seminal plasma of men in the general population, including fertile and infertile subjects, was measured. Semen samples were categorised as demonstrating oligospermia (sperm concentration < 20 x 10(6)/ml), asthenospermia (<50% motilesperm), oligoasthenospermia (a combination of the two criteria), and azoospermia (no sperm). An increase in lead and cadmium levels was observed in infertile men and there was a significant negative correlation of cadmium and lead semen concentration with sperm motility and sperm concentration in oligoasthenospermic men.
