Fluoride Affects Sperm Quality at Concentrations Found in Human Blood Following Use of Topical Fluoride Gels In 2002 and again in 2006, researchers from Poland reported that exposing ram semen to 0.38 parts per million (20 umol/L) of fluoride for 5 hours was sufficient to “cause a statistically significant decrease in the motility of spermatoza and the number of intact acrosomes.” (Zakrzewska 2002). As the authors noted, these changes would “undoubtedly affect the physiological function of the sperm.” Prior to the Polish team’s findings, researchers from Texas found that infusing testis with higher, but still relatively modest, levels of fluoride (4.75 ppm) “unequivocally” inhibited the synthesis of testosterone.
