For example, if an endometrial biopsy contains changes consistent with postovulatory days (POD) 2, 3 and 4, the pathologist should report the diagnosis as ' POD 4 or 18-day secretory endometrium'.Endometrial biopsies are not to be taken at the onset of bleeding in the following two conditions: if luteal phase defect (LPD) is suspected clinically and is desired to be confirmed histologically, when the biopsy should be taken between POD 7 (21st) and POD 9 (23rd) cycle days to demonstrate a 3–4 day delay in endometrial maturation; or if there are asynchrony of gland/stromal development and dissimilar maturation in different regions of the endometrial specimen.

Timing The best way to prove or disprove that ovulation has taken place is to take an endometrial sample on cycle day 22 or later, preferably at the onset of uterine bleeding.

By obtaining samples at the time of early uterine bleeding, the pathologist will be able to determine whether the bleeding is caused by the breakdown of postovulatory, secretory endometrium; by focal necrosis of the endometrium associated with anovulation; by other pathologic states; or by hormone administration.

Morphologically, the endometrium is one of the most dynamic target tissues in women.

Its cyclic structural changes mirror changes in metabolic functions, and both are regulated by ovarian estradiol and progesterone. Schematic representation of steroid hormone-morphologic interactions during the endometrial cycle.

Such a condition, also called irregular shedding, is presumably associated with a persistent corpus luteum from a recent or remote intrauterine or ectopic pregnancy and with relatively increased blood progesterone levels.
