Embryo resorption refers to a biological process in which the body naturally absorbs and eliminates the tissues of a developing fetus or embryo. This phenomenon commonly occurs in mammals, particularly in certain species, such as rodents, pigs, and rabbits.
During the early stages of pregnancy, if the developing embryo or fetus is determined to be nonviable or suffering from genetic abnormalities, the mother's body initiates the process of embryo resorption as a protective mechanism. The exact mechanisms behind embryo resorption are still not fully understood, but it is believed to involve a complex interplay of hormonal changes, immune system responses, and tissue remodeling.
Embryo resorption typically occurs without any visible external signs, making it a relatively secretive process. The process can be influenced by various factors, including maternal health, nutrition, stress, and genetic factors.
In some cases, embryo resorption might pose challenges to animal husbandry or reproductive research, as it can affect litter size and fertility. Understanding the underlying mechanisms and factors that contribute to embryo resorption is important for improving assisted reproductive techniques, animal breeding programs, and fertility treatments in both humans and animals.
Overall, embryo resorption is a natural process that enables the maternal body to remove nonviable embryos or fetuses, helping to ensure the survival and health of both the mother and potential offspring.
