Lack of food is a known trigger of embryonic diapause, but it has not been clear how nutrient depletion in the mother's diet is sensed by the embryo. "Seasonal starvation is one of the universal ...

It's challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That's why many mammalian embryos can postpone their growth to get through periods of environmental ...

Several animals can pause pregnancy, a strategy called embryonic diapause. This adaptation allows embryos to remain dormant until conditions improve for survival. Kangaroos and bears are among the ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the uterine wall—pausing pregnancy until she senses that her fat reserves are ...

The embryos of many species can stop developing when starved of nutrients, only to restart the process once these are restored – and scientists may have figured out how they do it. In the early stages ...

At some point in our evolution, we lost the ability to activate a reproductive mechanism called embryonic diapause, which slows development, usually during the blastocyst stage. And so, unlike mammals ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily slow ...

During diapause, the embryo remains free-floating and pregnancy is extended. This dormant state can be maintained for weeks or months before development is resumed, when conditions are favorable.
