Wonder why there is an approximate ratio of four boys to ever girl who gets Autism? The following quote might shed light on one possibility.

"Neurons that were pre-incubated with estrogen demonstrated substantial protection against thimerosal-induces neuronal death. In contract, the addition of testosterone caused a very large increase in thimerosal-induced death. A low nano-molar level of thimerosal that gave less than 5 percent neuron death in three hours could result in 100 percent cell death by the addition of one micromolar level of testosterone."¹
