Difference between Proliferative and Secretory Endometrium

Differences between Proliferative and secretory endometrium include:

Criteria	Proliferative Endometrium	Secretory Endometrium
Timing	Occurs in the first half of the menstrual cycle, before ovulation	Occurs in the second half of the menstrual cycle, after ovulation
Hormonal dominance	High levels of estrogen observed	High levels of progesterone observed
Endometrial Thickness	Endometrial thickness is around 2-3 mm	Endometrial thickness is around 5 mm
Cellular Changes	Primary follicle changes to Graafian follicle	Ruptured Graafian follicle changes into corpus luteum
Functional Significance	Prepares the endometrium for potential embryo implantation.	Creates a suitable environment for a potential embryo, therefore supporting the early stages of pregnancy
Duration	Typically lasts around 7 to 14 days	Lasts about 14 days but can vary
