What is the normal size of the uterus?

The uterus is a very important reproductive organ for women and is the place where life is conceived. Therefore, being able to maintain the normal condition of the uterus can prevent women from developing abnormal health conditions. For this reason, many women are very concerned about the size of the uterus and want to know what the normal size of the uterus is. So, what is the normal size of the uterus? Let’s take a closer look below.

The size of the uterus is 5.5-7.5cm in longitudinal diameter, 3.0-4.0cm in anterior-posterior diameter, 4.5-5.5cm in transverse diameter, and 2.5-3.0cm in cervical length. The uterus of an adult woman is about 7-8 cm long, 4-5 cm wide at the bottom, 2-3 cm thick, and weighs about 40-50 grams.

The normal range of uterine size varies at different times of the menstrual cycle:

The normal thickness of the uterus is different. If the endometrium is thick, menstruation is likely to be very painful and the fertilized egg will not be easy to implant. Generally speaking, the normal thickness of the endometrium is 0.2-1.0 cm. During menstruation, the functional layer of the endometrium is shed, leaving the basal layer. The normal thickness of the endometrium during the proliferative phase, which is the 6th to 14th day of menstruation, is about 1-3mm. The secretory phase is from the 15th to 28th day of menstruation, and the thickness of the endometrium is about 5-7mm.

Changes in the uterus after pregnancy:

After pregnancy, the uterus undergoes some changes to adapt to the growth and development of the fetus. Before pregnancy, the uterus is only the size of a small duck pear, weighing 50 grams and with a volume of approximately 7 cm * 4.5 cm * 3.5 cm. By full-term pregnancy, the uterus weighs 1,000 grams, which has increased 20 times, and can accommodate 5,000 ml of contents including the fetus and amniotic fluid. The full-term uterus is 35 cm long, 25 cm wide and about 22 cm thick.

The above is an introduction to the normal size of the uterus. I hope it will be helpful for women to understand. Many diseases in women's bodies are directly related to problems with the uterus. When related diseases occur, we must look for the cause from the uterus, and then take effective measures to treat it, strive to resolve the uterine problems as soon as possible to avoid more serious consequences.
