What is the thickness of the endometrium during ovulation?

The thickness of the endometrium during ovulation is about eight to nine millimeters. In fact, the thickness of the endometrium is different at different stages. When the menstruation just ends, the thickness is only one or two millimeters, and it is the thickest before the menstruation.

1. Menstruation has just ended and the endometrium is very thin, with a thickness of only 1-2mm, or only the endometrial line can be seen.

2. The endometrium during the follicular phase is approximately 6-7mm.

3. During ovulation, the thickness of the endometrium is 8-9mm. At this time, the dominant follicle is mature and the egg can break out of the follicle at any time.

4. Shortly after ovulation, the endometrium is about 10-12mm thick, which is the time when the fertilized egg implants. This thickness is just suitable for the implantation of the fertilized egg.

5. The thickness of the endometrium before menstruation is 14-16mm. Many patients believe that endometrial thickness is related to infertility. In fact, endometrial thickness is not the only factor leading to infertility. Changes in estrogen levels in the body directly affect changes in the thickness of a woman's endometrium, and monitoring the thickness of the endometrium through ultrasound can reflect the estrogen levels in the body. A thin single-line echo on ultrasound indicates low estrogen levels, while a woman's endometrium that is thicker than 14 mm indicates overstimulation by estrogen.

6. If the ovarian hormones are disordered, it can easily lead to abnormal thickening of the endometrium in women, which is called endometrial hyperplasia. It is caused by excessive amounts of itself irritating the endometrium. The clinical manifestations are irregular, heavy, abnormal uterine bleeding. Patients may experience continuous bleeding after a long period of amenorrhea, which may be suspected of miscarriage clinically. It may also manifest as shortened cycles and prolonged menstruation, with bleeding time lasting up to one month. The cyclical changes in endometrial thickness are regulated by secreted hormones and are closely related to the cyclical changes in the ovaries. The thickness of the endometrium changes continuously with the female menstrual cycle. Therefore, the thickness of the endometrium cannot be determined based on a single value. The reference values ​​of endometrial thickness are different in different physiological cycles, so the analysis should be based on the specific situation.
