[1] [5] A 2003 study by the group of Pendergrass et al. also using castings as a measurement method, measured vaginal surface areas ranging from 66 to 107 cm 2 (10.2 to 16.6 sq in) with a mean of 87 cm 2 (13.5 sq in) and a standard deviation of 7.8 cm 2 (1.21 sq in) [6]
Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry ...
In humans, the uterus is located within the pelvic region immediately behind and almost overlying the bladder, and in front of the sigmoid colon. The human uterus is pear-shaped and about 7.6 cm (3.0 in) long, 4.5 cm (1.8 in) broad (side to side), and 3.0 cm (1.2 in) thick. [2] [3] A typical adult uterus weighs about 60 grams.
Around 2–3 centimetres (0.8–1.2 in) in length, [3] it is the lower narrower part of the uterus continuous above with the broader upper part—or body—of the uterus. [4] The lower end of the cervix bulges through the anterior wall of the vagina, and is referred to as the vaginal portion of cervix (or ectocervix) while the rest of the ...
Up to 30% of women have a tilted uterus. Here's what causes it. Up to 30% of women have a tilted uterus, according to the International Society for Sexual Medicine.
The length of the vagina varies among women of child-bearing age. Because of the presence of the cervix in the front wall of the vagina, there is a difference in length between the front wall, approximately 7.5 cm (2.5 to 3 in) long, and the back wall, approximately 9 cm (3.5 in) long.
The pelvic exam during pregnancy is similar to the exam for non-pregnant women; however, more attention is given to the uterus and cervix. The size of the uterus is assessed at the initial visit, and the growth of the uterus is assessed at subsequent visits. In the first trimester the uterine size can be assessed on bimanual examination.
