Sorry, this is not a question. It is fact. Because I am pissed off!!!! at dermatologists for not saying it. I personally believe it is a DHT is the problem.
On http://www.propeciahelp.com/forum/viewtopic.php?f=3&t=3922 is an example of a guy who got crushed by Accutane. Personally I used Accutane (or roaccutane as it is called in Australia) for 1 month at 2 pills a day (15mg each i think), though i was sloppy and only averaged one. I went off it due to rashes and athletics, which it was affecting, and it was only after i stopped i noticed I COULD NOT get an erection. It didn't bother me at first, because I didn't masturbate that often, but after a few weeks I got worried and started looking into it, because I did want to have sex someday. At this stage I wasn't sure what it was, and eventually I came across other people who had suffered for years!! Just look it up on google. http://www.acne.org/messageboard/index.php/topic/260200-accutane-side-effects-are-we-missing-the-point/
This is another person who made the link i made, and typed DHT ACCUTANE on google. DHT (Dihydrotestosterone) is a hormone like testosterone, and funnily enough side effects for accutane and Dihydrotestosterone deficiency are familiar. http://en.wikipedia.org/wiki/Dihydrotestosterone
That was November last year. About 1 month after I stopped the Accutane I had an errection since I stopped accutane (I am not sure that while you are on it it affects you, maybe maybe not, i guess because you lips are bleeding and nose is bleeding so obviously you don't notice maybe???), and since then I think I have made an at least 50% recovery, but because I never really tried back then, because I thought I could always do it later, I don't know. There is this guy with the website called Kevin Pezzi, who had tonnes of interesting information, including information about Accutane, but he's also a douche because you have to buy it.
http://www.kevinpezzi.com/blog/why_I_wrote_The_Science_of_Sex.php explains his story, as he's also had roaccutane... I haven't bought it, and it's probably half bullshit, but Accutane certainly does have that effect on you, and he claims to be "even better than before" which is probably too good to be true.

Anyway, the gist of it is BE VERY CAREFULLLL with roaccutane. I couldn't find anybody else writing this question so I answered it myself. If any of you have any questions I will add additional details. I wasn't aware of the risks. I think if you can find a drug that increases DHT (Pezzi's wonder drug???) Then you could recover. I recovered naturally but I am young and very active, and only took one month of the 9 they prescribed (I would probably be permanently impotent if I had done that, because I reacted badly) Then again, many people have no problem, especially low dosage (10mg a day).

IF YOU EVER HAVE IT GET YOUR DHT MEASURED!! If this isn't proven soon they will just make more money and ruin more people's lives!! Please help me and inform people who have acne NOT to have this medication, or if they do they should have it on the bare minimum per day. I will unblock my history so you don't think I am dodgy, and if this contradicts anything I have said in the past, you can call Bul**hit. I am only a 16 year old who has done some research and connected the dots, and who had suffered because of roaccutane. Thanks for reading, you won't regret it

If you have questions I will answer using additioanl details. I am happy to hear any people who disagree, or have more questions to ask about it.
Sex offenders can get castrated, lol. But this is serious. Accutane is a shit drug. even if it affects "only" 1 in 10 that is still too high
