Follistatin - | FSHActivin - | FSHMIS (Mullerian Inhibiting Substance) - 8th weak of IULEstrogen - from androgen by aromataseIt has FSH, testosterone (receptors) sensitivity. They do not secrete testosteroneSecretory functionsAndrogen binding Protein (.ABP} - binds with DHT, testosterone & transport to epididymisH- Y antigen - development of gonadsAlso produce Plasminogen activatorBlood Testis Barrier (BTB)Paracrine effect on leydig cell
