| 摘要 |
The invention provides genetically modified non-human mammals and genetically modified animal cells containing a functionally disrupted PDE11A gene. Also provided by the invention are methods of screening for agents that modulate PDE11A to modulate spermatogenesis, methods of treating mammals to modulate spermatogenesis, and methods of modulating cAMP and cGMP signal transduction in cells that express PDE11A. The invention also provides agents and methods relating to the effect of PDE11A modulation (i.e. PDE11A inhibition or stimulation) on ex vivo spermatozoa capacitation and PDE11A stimulation on in vivo spermatozoa capacitation. The invention also relates to the effect of PDE11A modulation on male pro-fertility and female sexual dysfunction (FSD), specifically female sexual arousal disorder (FSAD), female orgasmic disorder (FOD), hypoactive sexual desire disorder (HSDD) or sexual pain disorders.
