Decidualization
Decidualization
Decidualization (pronunciation: /dɪˌsɪdʒuːəlaɪˈzeɪʃən/) is a process that occurs in the endometrium of the uterus during the menstrual cycle in preparation for implantation of an embryo.
Etymology
The term "decidualization" is derived from the Latin word decidua, meaning "falling off", which refers to the shedding of the endometrial lining during menstruation.
Process
During decidualization, the stromal cells in the endometrium undergo a transformation into a specialized type of cell known as a decidual cell. This process is triggered by the hormone progesterone, which is produced by the corpus luteum after ovulation. The decidual cells provide a supportive environment for the potential implantation and growth of an embryo.
