Abstract
The relationship between duration of exposure to fluoridated public water supplies and measures of child health and behaviour was studied for a birth cohort of Christchurch children. This study showed no association between exposure to fluoridated water and a large range of measures of child health and behaviour taken during the period from birth to seven years, even when the possible effects of family social background were taken into account statistically.

Impact of 12-week ingestion of sodium fluoride on aggression, sexual behavior, and fertility in adult male rats
Ingestion of sodium fluoride at 100 and 300 ppm in drinking water for 12 weeks by adult male Sprague-Dawley rats was investigated for effects on territorial aggression, sexual behavior, and fertility. Body weight and absolute and relative testes weights were not affected, but the average weights of epididymis, ventral prostate,

Chronic aluminum fluoride administration. I. Behavioral observations
This study examined the behavioral effects of chronic ingestion of various monofluoroaluminum complexes (AlF3) in drinking water. Forty young adult male Long-Evans rats were divided into four groups of 10 rats each. The groups received different concentrations of AlF3 in the drinking water from three sample solutions having a total

Water treatment with silicofluorides and lead toxicity
Toxic metals like lead, manganese, copper and cadmium damage neurons and deregulate neurotransmitters like serotonin and dopamine (which are essential to normal impulse control and learning). Earlier studies show that - controlling for socio-economic and demographic factors - environmental pollution with lead is a highly significant risk factor in predicting

Perinatal exposure to sodium fluoride with emphasis on territorial aggression, sexual behaviour and fertility in male rats.
Territorial aggression, sexual behaviour and fertility parameters were evaluated at adulthood of male rats previously exposed to different concentrations of sodium fluoride (Na-F) at their gestation, lactation and postweaning period till maturation. Sixty weanling male Wistar rats were received Na-F via their dams from second trimester of their pregnancy onward

Neurobehavioural effects of developmental toxicity
Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review

Fluoride's Direct Effects on Brain: Animal Studies
The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.

Fluoride's Effect on Fetal Brain
The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

Fluoride & IQ: 68 Studies
As of February 2021, a total of 76 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 68 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies have found that fluoride exposure impairs the learning and/or

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out
