Semen quality in welders exposed to radiant heat.

摘要: Several studies suggest that welding is detrimental to the male reproductive system. Welding fume and radiant heat are of interest as possible causal factors. This study investigates semen quality sex hormone concentrations among 17 manual metal arc alloyed steel welders with a moderate exposure (globe temperature ranging from 31.1 degrees 44.8 C), but without substantial toxicants. During skin in groin increased on average by 1.4 C (SE +/- 0.72 C). Sperm count motile sperm were non-significantly reduced comparison two different reference groups. Within group proportion normal shape declined significantly after six weeks break exposure. concentration had same pattern intraindividual change relation heat, changes not statistically significant. No consistent hormones found. The investigated more exposed than general. results experienced reversible decrease quality, most likely caused (about five hours day through several weeks). It remains be established if even lower levels general population has any impact fertility.
