Involution is the medical term meaning shrinkage of a gland with age, as with the normal developmental involution of the thymus.

During pregnancy, the uterus stretches to accommodate the growth of the fetus. Involution occurs postpartum and is when the uterus contracts to return to its preprgnant size.

Agrarian involution refers to a state where a society becomes stuck or stagnant in its agricultural practices without fully progressing or developing. This can result in increased societal complexity without corresponding technological advancements or increased productivity in agriculture. Agrarian involution can lead to social, economic, and political challenges within a society.
