The anterior position of the uterus usually does not become posterior. Although the uterus has a certain degree of mobility in the pelvic cavity, its activities are bounded by the uterine ligament and its range of activities is limited, so it is difficult to change the uterus from anterior to posterior position. The position of the uterus has no effect on normal sexual life, but relatively speaking, a posterior uterus is less likely to conceive. After pregnancy, the uterus gradually increases into the pelvic cavity, the center of gravity of the uterus will change, and the position of the uterus will also change, possibly from an anterior uterus to a posterior uterus, or the original posterior uterus to an anterior uterus, which is a normal physiological change and does not require intervention, and will return to the original normal uterine position after delivery. This is a normal physiological change and does not require intervention.
