What is the normal size of the uterus?

Like other organs, the size of the uterus also has normal values. However, the size of a woman's uterus can change at different stages of life. Even some abnormal diseases in women are caused by problems with the size of the uterus. Many women become infertile because their uterus is too small. Therefore, it is very necessary to understand the condition of the uterus. So, what is the normal size of the uterus?

The uterus is a complex structure located at the top of a woman's vagina. The structures of the uterus from outside to inside are the serosa, muscularis, and mucosa. The uterine wall is divided into three layers from outside to inside: the exometrium, myometrium and endometrium.

What is the normal range of uterine size?

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.

The above is an introduction to the normal size of the uterus. I hope it will help you understand. After understanding the normal range of the uterus, in daily life, if you find that the size of the uterus is abnormal, it is best to go to a regular hospital for examination. The key is to be afraid that it will cause a greater impact on women's health, so timely treatment is still very necessary.
