Female sexual receptivity in mice and rats is mediated by the progestin receptors. Mani et al. found that antisense nucleotides to DARPP-32, a dopamine- and cAMP-regulated protein, as well as DARPP-32 knockout mice, demonstrated decreased sexual receptivity in response to stimulation of progestin receptors or dopamine receptors. The data suggest that the dopamine and progestin pathways converge at the level of DARPP-32 to regulate sexual receptivity.
