How much is the thickness of the uterus normal?

Endometrial thickness varies from one menstrual cycle to the next. In the first half of the menstrual cycle, endometrial thickness ranges from 0.3 cm to 0.8 cm. After ovulation, endometrial proliferation thickens. At the same time, progesterone acts. In the second half of the menstrual cycle, endometrial thickness can reach 0.8 cm to 1.2 cm. In the case of 1.2cm thickness, it is normal to be able to menstruate in time. If the thickness of endometrium reaches 1.2cm and menstruation is delayed, it belongs to abnormal thickening of endometrium. It is necessary to do curettage surgery and send endometrium for pathological examination.
