What is pseudodecidua?

Answer 1

Pseudodecidua is a term used to describe a condition where the endometrial lining of the uterus undergoes changes similar to those seen in true decidua, but without an actual pregnancy. This can occur in response to hormonal influences, such as during the menstrual cycle or due to certain pathological conditions. Unlike true decidua, which forms during pregnancy and is essential for embryo implantation and development, pseudodecidua does not support fetal growth. It may be observed in cases of ectopic pregnancies or in the context of hormone treatment.
