| Abstract: | In 20,915 normal married women, the position
of their uterine cervices was measured by the
distance from the cervix to the hymen ring and
also from the cervix to the plane of tlie ischial
spine. Figures shOw that taking the ischial spine
as the landmark, the normal level should be
below it with the lowest location 2.5 cm below
the ischial spine. Mean cervix ring conjugate
is 4.92±0.88 cm with straining. Therefore, it is
reasonable to take the standard cervical position
as more than 4 cm above the vaginal orifice or
3.5 cm from the hymen ring.
Statistical analysis reveals that in uterine
atrophy among old menopausal and lactating
women, the uterine position is virtually higher
a.nd the position of the retroposed uterus is
lower. The descent of the uterus is more mark-
ed in the retroposed uterus during straining. The
cervical location is lower in multiparas with in-
creasing in number of delivery and so multipara
is an important cause of uterine prolapse. |
