23

saw palmetto is better for what stage BPH

mild to moderate

24

MOA PDE 5 inhibitors

selective inhibition of PDE-5 increase intracavernosal cGMP levels and causes relaxation of the nonvascular smooth muscle of corpora cavernosa

adverse effects PDE 5 inhibitors

visual changes and hearing loss

28

will PDE5 inhibitors work in men with loss of potency due to a cord injury

no

29

why does an erection require relaxation of nonvascular smooth muscle

permits inflow of blood which P causes the erection
