Embryonic diapause is a state of stopping the development of the embryo that can occur in many species of animals, including some mammals, amphibians, fish, and insects. These animals suspend pregnancy in order to survive in difficult environmental conditions, such as lack of food, droughts, frosts or other adverse factors. Diapause allows them to survive in harsh conditions and to continue development again when conditions become more favorable.

In order to maintain diapause, organisms make various biochemical adaptations. First of all, the rate of metabolism and the activity of internal organs and the coagulation of blood and ovarian hormones decrease. The increased amount of glycogen or lipoprotein stored in the cells intended for diapause provides the source of energy needed to maintain it. Physiological moods for regulating body temperature sometimes play an equally important role in prolonging this phase. Stopping reproduction may have a protective function or help reduce environmental stress for the mother or offspring.
The animals that can stop pregnancies include: skunk, badgers, lizards, rats, voles and voles, roe deer, frost hedgehogs.

Which animals can hold a pregnancy (embryonic diapause)? Some mammal species, such as bears, raccoons, foxes, coyotes, wolves and echidnas, are able to suspend pregnancy (embryonic diapause) in response to changing environmental conditions such as lack of food or adverse climatic conditions. Pregnancy can also be artificially induced in mice, rodents, and some mammal species for research purposes.
