What are the two factors that bring about involution of the uterus?

Uterine Involution

Involution is thought to be driven by uterine muscular contractions, turnover of the extracellular matrix, necrosis and sloughing of the uterine caruncles, and regeneration of the endometrium (Gier & Marion 1968).

When does thymus undergo involution?
