Two guys have a bit of "locker room" type talk about "Are you going to tap that?" etc. Lewd comments.

One of the female patients is fully nude for about 30 sec to 1 min in the last quarter of the movie. This is non-sexual in nature. The patients are told that there is to be no sexual activity while on the trial and one patient asks if masturbation is included. There is no other sexual content in the movie.

A very brief view of a man nude from the back including his buttocks.

There are several violent attacks and quite a bit of blood/gore.
