Definition
- Adjective: Lacking gonads; being without the reproductive glands (testes or ovaries).
Usage
The adjective "agonadal" is a specialized medical and biological term. It is used to describe an organism, typically an animal or a human, that is born without gonads or has had them removed. It is not used in everyday conversation. * It is most accurately applied as a descriptor preceding a noun (e.g., an agonadal condition) or following a linking verb (e.g., The patient is agonadal). * It is a neutral, clinical term and does not inherently describe the cause (congenital absence vs. surgical removal).
Examples
- The rare genetic condition resulted in the fetus being agonadal.
- Studies on agonadal mice help researchers understand hormone-dependent development.
- After the radical surgery, the patient was permanently agonadal.
Advanced Usage
