High Exposure to Boron in Drinking Water and Sperm Parameters in Chilean Young People

Our aim was to describe sperm parameters in residents from Northern Chile. We evaluated in 101 volunteers (18 and 30 years old) urinary and drinking water Boron levels using Inductively Coupled Plasma Mass Spectrometry; semen parameters were measured with standardized methods. Each individual was ca...

We evaluated in 101 volunteers (18 and 30 years old) urinary and drinking water Boron levels using Inductively Coupled Plasma Mass Spectrometry; semen parameters were measured with standardized methods. Each individual was categorized in 3 levels of exposure: low (B levels in urine 2.94 mgL-1 or tap water 3.0 mgL-1), medium (urinary B between 2.95-7.4 mgL-1 and B in tap water with 3.0-7.0 mgL-1) and high (urinary B > 7.4 mgL-1 or tap water > 7.0 mgL-1). We found no significant differences among groups by pH, sperm concentration (45.1; 48.2 and 38 million/mL), motility 1th hour (38.1; 40.0 and 45.5 %) and vitality 1th hour (88.6; 88.0 and 76.9 %) respectively.
