Innate defenses against environmental particulate exposures can become deficient when physiological background of the organism is unbalanced. Even those exposures considered innocuous may then become harmful. For example, one of the important inherent risks of pregnancy is increased inflammatory responsiveness

Under estrogen deficiency, blastocysts cannot initiate implantation and enter dormancy. Dormant blastocysts live longer in utero than normal blastocysts, and autophagy has been suggested as a mechanism underlying the sustained survival of dormant blastocysts during delayed implantation. Autophagy is a
