This is something you must talk over with your doctor, preferably a psychiatrist versed in autism and related disorders. I'd also suggest a counselor versed in both autism and teenage issues.

All teens feel the urge to physically lash out when upset... and people with autism do not have the constraints that are taught to others sensitive to social "feel." It takes you, working with professionals who know your son and your family dynamics, to come up with a plan to help him find a way to handle normal teenage moods in a positive manner.

My son does require medication to control his moods... but then he is not "just" on the autism spectrum. He also has schizoaffective disorder, and his neuro-chemistry is off-kilter. He takes meds for that, just like a diabetic takes meds because of insulin production being off-kilter.

Finding a counselor versed in teen autism can help a lot.

My children are not teenagers, but I would recommend considering the change in hormone levels normal for puberty. In one of Temple Grandin's books, she wrote a whole chapter about how her hormonal changes made a huge difference her her coping skills at different stages in her life cycles. I would assume it is the same for males.
