Neural pathways for different types of erections:
|Chronic medical conditions||

|Exercise||Extensive bicycling and prolonged pressure on pudendal and cavernosal nerves increase the risk of ED. Regular Regular Insulin aerobic exercise not associated with nerve compression Nerve Compression Brachial Plexus Injuries decreases the risk of ED.|
|Penile conditions||Peyronie disease Peyronie Disease Penile Anomalies and Conditions|
|Medications||Mechanism of action||Side effects|
||PDE5 inhibitors → increase intracavernosal cGMP cGMP Guanosine cyclic 3. Phosphodiesterase Inhibitors → increase intracavernosal NO||
|Alprostadil Alprostadil Coarctation of the Aorta||PGE1 agonist → increase cAMP cAMP An adenine nucleotide containing one phosphate group which is esterified to both the 3′- and 5′-positions of the sugar moiety. It is a second messenger and a key intracellular regulator, functioning as a mediator of activity for a number of hormones, including epinephrine, glucagon, and acth. Phosphodiesterase Inhibitors, decrease Ca CA Condylomata acuminata are a clinical manifestation of genital HPV infection.
