概括的真好！谢谢

 I will be very careful when you are applying endometrial dating soly based on histopathology, since recent studies have shown that histopathologic endometrial dating is not accurate and not reliable. Therefore, in daily pathology practice, if the patient is not coming for infertility, it is not necessory to give endometrial dating.

I quote the abstract of Dr. Murray's recent publication below for your reference.

A critical analysis of the accuracy, reproducibility, and clinical utility of histologic endometrial dating in fertile women.

OBJECTIVE: To refine or redefine the traditional histologic criteria used to date the secretory phase endometrium. DESIGN: Randomized, observational study. SETTING: Academic clinical research center. PATIENT(S): One hundred and thirty healthy, regularly cycling, fertile volunteers, aged 18 to 35 years. INTERVENTION(S): Patients were randomized to undergo endometrial sampling and measurement of serum estradiol and progesterone 1 to 14 days after the midcycle urinary luteinizing hormone surge. Three gynecologic histopathologists objectively scored each tissue specimen for 32 distinct histologic features and dated the endometrium using traditional histologic criteria. MAIN OUTCOME MEASURE(S): The 32 features were evaluated for [1] temporally dependent variation, [2] the amplitude of variations in score observed across the secretory phase, and [3] interobserver variability. Additionally, traditional dating criteria were analyzed. RESULT(S): The traditional endometrial histologic dating criteria are much less temporally distinct and discriminating than originally described, due to considerable intersubject, intrasubject, and interobserver variability. Neither traditional dating criteria nor any combination of the best performing histologic features identified by our objective and systematic analyses could reliably distinguish any specific cycle day or narrow interval of days. CONCLUSION(S): Histologic endometrial dating does not have the accuracy or the precision necessary to provide a valid method for the diagnosis of luteal phase deficiency or to otherwise guide the clinical management of women with reproductive failure.

 谢谢杨斌老师！杨老师在16楼提醒大家：

仅依据组织学进行子宫内膜按日分期并不准确可靠。日常工作中，如果不是不孕症患者，不要进行按日分期。
