>>13108324>Effect of duration of fluoride exposure on the reproductive system in male rabbitshttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC3017333/The present study demonstrates that fluoride hampers the reproductive functions of male rabbits and is proportional to the duration of fluoride exposure.

>Effect of fluoridated water on intelligence in 10-12-year-old school childrenhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC5285601/A significant inverse relationship was found between the fluoride concentration in drinking water and IQ (r value = −0.204; P < 0.000). It was observed that IQ level was negatively correlated with fluoride concentration in drinking water.
>Prenatal Fluoride Exposure and Cognitive Outcomes in Children at 4 and 6–12 Years of Age in Mexicohttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC5915186/Higher prenatal fluoride exposure, in the general range of exposures reported for other general population samples of pregnant women and nonpregnant adults, was associated with lower scores on tests of cognitive function in the offspring at age 4 and 6–12 y.
>Developmental Fluoride Neurotoxicity: A Systematic Review and Meta-Analysishttps://ehp.niehs.nih.gov/doi/10.1289/ehp.1104912Children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas. The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment.
>Fluoride deposition in the aged human pineal gland.https://www.ncbi.nlm.nih.gov/pubmed/11275672The purpose was to discover whether fluoride (F) accumulates in the aged human pineal gland. There was a positive correlation between pineal F and pineal calcium (Ca) (r = 0.73, p<0.02) but no correlation between pineal F and bone F. By old age, the pineal gland has readily accumulated F and its F/Ca ratio is higher than bone.
