Poor semen quality in men possibly due to chemicals

No surprise common chemicals in everyday products (e.g., parabens) may contribute to infertility:

(Reuters Health) - Men who have been exposed to common chemicals known as parabens have lower testosterone levels and more sperm that are abnormally shaped and slow moving, according to a study that suggests these ingredients may contribute to infertility.
Researchers examined lab tests done on 315 male patients of a fertility clinic in Poland to pinpoint issues they were having with reproduction. All of the men provided samples of urine, saliva, blood and semen for analysis.
Compared to men who had low concentrations of parabens in their urine, men with high concentrations of the chemicals also had a larger proportion of sperm with the abnormal morphology that’s associated with infertility, the study found.
Higher levels of parabens in the urine were also associated with DNA damage in the sperm and with decreased sperm motility, which may contribute to infertility.
