Testosterone improves spatial cognitive dysfunction via androgen non-genomic effeet in Tfm mice

The non-genomic actions of androgen on cognitive function have been extensively studied.However,the underlying mechanisms remain controversial.In this study,we used testicular feminized(Tfm)mouse as a cell research model,which had androgen receptor deficiency and low circulating testosterone level,to investigate whether testosterone improves spatial cognitive dysfunction via its androgen non-genomic actions.We found that testosterone supplementation can improve the spatial cognitive function,hippocampal neuron danage and dendritic spine density in Tfm mice,but no statistical difference was found in fear memory function.
