Component in soy products causes reproductive problems in laboratory mice

... pups in each litter, and fewer pregnancies. Mice receiving the highest level of genistein, 50 mg/kg per day, had a high percentage of egg cells that remain in clusters, unable to separate and therefore develop abnormally. The researchers explain that oocytes that remain in clusters are less likely to become...

The major antipsychotic drugs are believed to "dial down" the dopamine machinery by blocking receptors for dopamine on the surface of neurons. Also, amphetamines, which release dopamine, are known to aggravate schizophrenic symptoms. The re...
