- - - - Neuropeptide from hypothalamus and tonic center
        
        Acts on anterior pituitary to released LH & FSH
    - - Glycoprotein released from anterior
        pituitary in response to GnRH
        
        Targets the testis and ovaries
        
        stimulates testosterone production
        
        stimulates ovulation, formation of CL, & progesterone secretion
    - - Glycoprotein released from the anterior pituitary in response to GnRH
        
        Targets sertoli cells in testes and granulosal cells in the ovaries
        
        follicle development and estradiol synthesis
        
        sertoli cell function
