Mechanism and action
Addyi: Sexual desire is modulated by complex central nervous system pathways involving serotonin (generally inhibitory) and dopamine and norepinephrine (generally excitatory). Propecia: DHT, produced from testosterone by 5-alpha-reductase, drives miniaturisation of scalp hair follicles in genetically susceptible men, gradually shortening anagen growth phases until follicles produce only fine vellus hair…
