Patient's question:
What is the normal thickness of the endometrium at different periods? Thank you!First follow-up question: How can luteal phase deficiency be identified? What tests should be done? When is the best time to get tested?
Second follow-up question: Measuring basal body temperature is troublesome. To determine if luteal phase function is insufficient, can a blood test for progesterone be used instead? When is the best time to take a blood test for accuracy?
Third follow-up question: I took a blood test on the 3rd day of my period, and the results showed only elevated testosterone levels, with everything else normal. However, I don’t know on which day to test for a more accurate assessment of luteal phase deficiency.
Doctor's answer:
Generally, the thickness of the normal endometrium varies between 5-10mm. The thickness of the endometrium also differs at different periods:1. In the proliferative phase, the endometrium is about 9-10mm thick.
2. In the secretory phase, the thickness of the endometrium is approximately 5-6mm.
3. During the menstrual phase, the thickness of the endometrium can reach 8-10mm.
