Position of the Womb

Categories: Obstetrics or Midwifery

At four months the top of the womb has risen above
the pelvic brim bone in front; at five months, it is midway between the

bone (pubic) and the navel; at six months, it is at the navel; at seven

months, it is four fingers breadths above the navel; at eight months, it

is midway between the navel and the bottom of the breast bone; at nine

months, it is to the breast bone; from the middle to the end of the ninth

month, the top of the womb sinks to about the position occupied at the

eighth month.



Twins occur about once in ninety to one hundred and twenty, triplets once

in one thousand eight hundred and seventy-five, and quadruplets once in

three hundred and seventy-one thousand one hundred and twenty-six

pregnancies. The causes are unknown. Twin conception is more common in

women who have borne children, and more so in the elderly than in the

young, first bearing women (primiparae).
