Stop drunk posting!
And yes, Youtube allows medical videos contained nudity. It's the typical American hypocrisy where nudity is EVIL and BAD and SINFUL unless it's a doctor going second base on his patient or, aparantly, a bunch of girls touching eachother's boobs in search for lumps. Took a vid on the beach while on holliday? Sorry, Youtube will delete it even if there's just half a second of topless girl bathing in the sun.
I think it's more worth taking a look at how Youtube has become lame in other ways. The amount of content getting deleted left and right is really disheartening and while most of the content DOES have copyrighted material, the idea behind the deleting is ridiculous. Spending hours creating a video review of a movie which contains some short clips, only for Youtube to delete it after a day is not going to make anyone happy.
