8 mm thickness is normal.

Endometrium 8mm is generally normal, belongs to the endometrial thickness near ovulation. Each person's endometrial thickness has a certain difference, even if it is the same patient, the thickness of the endometrium will change with the menstrual cycle within a large range. For example, just after menstruation is clean, that is, after the endometrium has just been stripped, the endometrium is generally very thin, and will gradually thicken to 8~12mm during ovulation. If the endometrium is too thick or too thin during ovulation, it may affect embryo implantation and affect the chance of pregnancy. Some patients need to do endocrine tests, so they need to do treatment.
