Orchiectomy is not a cure for sexual addiction
. This is a radical procedure that can lead to a tremendous amount of irreversible physical and mental after effects and I doubt you will find a competent surgeon who is willing to perform this procedure for this indication. Remember that even removing one testicle (unilateral Orchiectomy) will be unlike to drop your blood testosterone
levels sufficiently to see a diminshment in your sex drive. On the other hand, there are medications that can be given to try to block androgens
at the level of the brain and thereby reduce sex drive. You are far better to consult an endocrinologist
regarding these treatment strategies. Best of luck and health to you. I hope you find a way to treat your complex problem effectively.
