Abstract

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.

摘要

对普通人群中男性（包括生育能力正常和不育的男性）精浆中的铅和镉浓度进行了测量。精液样本被分类为少精子症（精子浓度<20×10⁶/ml）、弱精子症（活动精子<50%）、少弱精子症（两种标准的组合）和无精子症（无精子）。在不育男性中观察到铅和镉水平升高，并且在少弱精子症男性中，镉和铅的精液浓度与精子活力和精子浓度呈显著负相关。
