Furthermore, selective inhibitors of PDE11 have not been reported. However, recent studies with a PDE11 knockout mouse model have been interpreted to suggest that PDE11 may be important for sperm development and function. Ejaculated sperm from knockout mice displayed slightly lower sperm concentration and decreased viability compared with controls, and the sperm had a lower rate of forward progression (Wayman et al., 2005). However, the animals were fertile. Moreover, it is still not clear whether PDE11 is expressed in reproductive tissue of the mouse.
