MCQ: erectile dysfunction

A 55-year-old married patient complains of erectile dysfunction. The man has Parkinson disease that is well controlled with L-dopa and he is able to work full time. He also has a part-time job that causes him to work late most evenings. The patient also relates that he drinks two martinis each evening, smokes two packs of cigarettes a day, and sometimes uses cocaine. His sexual dysfunction is most likely to be associated with his
(A) work schedule
(B) cocaine use
(C) L-dopa use
(D) alcohol drinking
(E) cigarette smoking

 

alcolol use

 

y not cocaine ?

 

cocaine use ,do causes erectile dysfuntion and it is common also,but i think it is temporary,moreover,cacaine abuse also increase sex drive somehow....... m i right ? however ,in the case ,it is mentioned ,occasional cacaine use and two martinis every evening,and thts too much ...... so i went for alcohol abuse . What do u say ?

 

yes u r ryt that Cocaine users often report heightened libido, but cocaine abuse can also cause erectile dysfunction and impotence.
yes alcohol do interfere with sexual drive and also causes erectile dysfunction, but tobacco use does the same.
L-dopa improves the dysfuction
but here in this question, 2 packs a day smoking i think is a right answer.

 

cocaine

 

why cocaine, summara? explain !

 

smoking .. coz 2 packs daily

 

hi,
(B) cocaine use
(D) alcohol drinking
(E) cigarette smoking

 

I guess alcohol

 

I think two packs cigarette is the right answer ,,,,,i have few reason ,there are many people taking cocaine,Alcohol and martini,these things always cause libido,and l dopa is used to treat the disease of Parkinson's which is a disease in which degeneration of dopaminergic neuron of pars compacts of substantia Nigra occurs resulting in low level dopamine causes muscle tremor,slowness of movement ,gait muscle weakness etc

Wel erection is under the control of parasympathetic activity and emission is under the sympathetic , so with the use of cocaine patient will have less erection you can say no erection because cocaine is sympathomimetic . this guy is using it occasionally not usually so this one is ruled out..
Considering smoking as a risk factor for erectile dysfunction is some what controversial but in a long run it can indirectly affect the penile erection through different mechanism such as heart dysfunction, vascular complaiance and decrease oxygenation through chronic lung diseases.
L dopa I think it improves erection in pd patients. first hormonaly by decreasing prolactin release (tubulo infundibular pathway) second dopamine itself is a vasodilator.
Chronic Alcoholism is definitely the most common cause of erectile dysfuntion.
by the way workplace stress can also cause Erectile dysfunction because of tiredness but its not as common as Alcoho
although many options in the scenario can cause Erectile dysfuntion but in this situation i think Alcohol is the suitable answer
So i will go for Alcohol. option D
