Prostate & Male Urological Disorders

Diagram showing testosterone converted to dihydrotestosterone by 5α-reductase, which is inhibited by finasteride and dutasteride; dihydrotestosterone binds an androgen receptor in a prostatic cell to promote cell growth.

5-Alpha-Reductase Inhibitors

Diagram showing sexual stimulation releasing nitric oxide, activating guanylate cyclase and increasing cGMP; PDE type-5 inhibitors block PDE5, leading to arterial smooth muscle relaxation and increased penile blood flow.

Phosphodiesterase Type-5 Inhibitors

Diagram showing alpha-1 blockers preventing noradrenaline and adrenaline from activating alpha-1 receptors, leading to smooth-muscle relaxation and widening of the urethra.
