30秒でわかる単語
- Inner lining of the uterus
- Sheds during menstruation
- Crucial for pregnancy
Overview
The endometrium is a specialized tissue found in the female reproductive system. It is the innermost lining of the uterus and functions as the “soil” for a fertilized egg to implant and grow. Its structure and thickness change dynamically throughout the menstrual cycle in response to hormones like estrogen and progesterone. If fertilization does not take place, the functional layer of the endometrium breaks down and is expelled from the body during menstruation (a period).
Usage Patterns
This term is primarily used in medical, biological, and health contexts. It is a formal, scientific noun and is rarely used in casual conversation unless discussing specific health conditions like endometriosis or fertility issues.
- Written: Common in medical textbooks, health reports, and articles about women's health.
- Spoken: Used by doctors (gynecologists), researchers, and patients discussing reproductive health.
Common Contexts
- 1Medical Diagnoses: When discussing conditions like endometriosis (where tissue similar to the endometrium grows outside the uterus) or endometrial cancer.
- 1Fertility and Pregnancy: In discussions about the thickness of the uterine lining required for successful embryo implantation, particularly in IVF treatments.
- 1Menstrual Health: When explaining the biological process of menstruation to students or patients.

How to Use It

Use 'endometrium' when discussing the specific tissue layer. For general discussions about the organ, 'uterus' or 'womb' is preferred. Adjective form is 'endometrial' (e.g., endometrial ablation).
よくある間違い
Learners often confuse 'endometrium' with 'endometriosis'. 'Endometrium' is the tissue itself, while 'endometriosis' is the medical condition involving that tissue.
