IPA: /ɔːˈtɒdʒənəs/
KK: /ɔːˈtʌdʒənəs/
Relating to something that originates from within the same individual or is self-generated, often used in medical contexts.
The doctor recommended an autogenous vaccine to boost the patient's immune system.
Autogenous is formed from "auto-" (meaning self) and "genes" (from Greek "genes", meaning born of or produced by). The word describes something that is produced or generated by itself.
Think of 'self' ('auto-') and 'produced' ('genes') to remember that autogenous means something that is generated by itself.
