Involution is a process in which the process of realization or progress of something stops. It could be considered that involution is the antonine or opposite of evolution. The term is used in three essential fields of society, administrative, health and scientific. In the administrative field, there are many procedures that involve the implementation of mechanisms linked by a chain of command or operations, this guarantees the proper functioning of the realization of the final product, but when a link in this chain stops or desynchronizes, the factory stops, in this aspect, the involution is of the blocking type, since it stops the process, however it does not retract. When the problem item resolves, the process is returned to its course.

In terms of health, an involutionary process implies that the studies, treatments and operations that have been performed on a patient do not generate the expected effects, even worsening the symptoms, here if there is involution that delays the chain of objectives. When we hear “The patient has not progressed satisfactorily in the fight against the disease” there is a regression in the patient’s health. The mechanism of reproduction of a woman is surprising, when the fetus leaves the womb, it begins to retract, to return to its normal size, this symptom is called uterine involution. The term is also applied to the reduction of bumps on the body.

In the scientific field, when studies of the matter are carried out, and the results are negative or do not follow the expected course, they are considered involutional.
