Relating to gender reassignment surgery.

SB 899 prohibits physicians in Oregon from performing irreversible gender reassignment surgeries on minors under 18 years old. The bill specifically bans procedures like hysterectomy, orchiectomy, vaginoplasty, and certain genital surgeries for biological males or females. Exceptions apply for medical conditions such as disorders of sex development, treatment of complications from prior procedures, or life-threatening physical injuries requiring immediate surgery. The law directly affects minors seeking these surgeries, their healthcare providers, and medical facilities, while defining "biological sex" based on reproductive anatomy at birth.
