Prenatal exposure of male mice to androgen increases neuron number in the hypogastric ganglion

Abstract

There is a sexual dimorphism in the hypogastric ganglion innervating the internal genitalia of mice. We now report that prenatal exposure of male mice to testosterone propionate brings about a significant increase of neuronal number in the hypogastric ganglion. This suggests that sexually dimorphic nature of the hypograstric ganglion depends on the prenatal hormone environment.
