Oregon Revised Statutes Procedure in Criminal Matters Generally § 137.525

(1) If a person pleads guilty or no contest to, or is found guilty of, a crime described in ORS 163.305 to 163.467, and if the court contemplates sentencing the person to probation, the court, before entering judgment, may order that the person undergo an examination by a psychiatrist or other physician found qualified and appointed by the court to determine whether available medical treatment would be likely to reduce such biological, emotional or psychological impulses, including any paraphilia, which may be the cause of the criminal conduct and, if so, whether the person is a suitable candidate medically for such treatment. Such medical treatments may include the taking of prescribed medication.

(2) If the examining psychiatrist or other physician reports that available medical treatment would be likely to reduce the biological, emotional or psychological impulses that were a probable cause of the criminal conduct, and that the person is a suitable candidate medically for such treatment, the court may include as a condition of probation that the person participate in a prescribed program of medicine and accept medical treatment at the person's own expense under the care of the psychiatrist or other physician appointed by the court and that the person faithfully participate in the prescribed program of medical treatment during the course of the probation.

(3) A sentence of probation under this section shall not be imposed except upon the written consent of the convicted person. Probation under this section may be revoked upon any failure of the convicted person to cooperate in the treatment program, including, but not limited to, any failure to meet with the treating physician as directed by the physician or to take medication or otherwise to participate in the prescribed program of medical treatment during the course of the probation.
