Anterior and posterior uterine positions have nothing to do with vaginal depth. 1. Anterior and posterior uterine positions: both uterine positions are normal, and another normal position is the flat uterine position; none of these three uterine positions affects the normal vaginal depth; the exit cervix of the uterus is deep in the vagina, dividing the bottom of the vagina into four fornices; the body of the uterus and the vagina do not lie in a single space, and so have no effect on the depth of the vagina. 2. Vaginal depth: the vagina is connected to the lower part of the cervix on the upper part of the vagina and the vulva part on the lower part; the cervix protrudes from the top of the vagina and divides the vagina into four fornices in the anterior and posterior regions; the posterior fornices are deeper, the length of the posterior wall of the vagina is around 7-10cm, and the length of the anterior wall of the vagina is around 6-8cm. Uterus anterior posterior and vaginal depth if found abnormal, need to go to the hospital in a timely manner to clarify the diagnosis, by the doctor according to the specific circumstances, the formulation of individualized diagnostic and treatment plan for standardized treatment.
