Does the endometrium thicken during ovulation?

Patient's question:

No

Doctor's answer:

The normal thickness of the endometrium is 8—12 mm. A few days before the menstrual period, the endometrium thickens. During ovulation, it should be no less than 0.8 cm to have a chance of pregnancy. If it is greater than 1.4 cm, pregnancy is also impossible.
