Comparison of infertility rates in communities from boron-rich and boron-poor territories

As a part of a large-scale work aimed at studying the health effects of boron (B) in residents of a country with the world’s largest supply, developmental effects of B are presented. Spontaneous abortions, stillbirths, and congenital malformations in addition to early infant mortality were questioned in the field by home visits. Although the number of families so far ascertained is rather small, the rates related to spontaneous abortions and stillbirths from high B exposure vs low B exposure subpopulations revealed no differences of significance, providing no evidence that B affects human development adversely.
