Wombs for WisdomTM
Dear Womb Curious!
Thank you for inquiring about the medical data sources I
use for my art.
you are seeking a science-only
based model, I encourage you to own one! They are
are some of the sources I've used to inform my art:
“In the non-pregnant state, the uterus is about 3 inches long, 2 inches wide, and 1 inch thick,
and weighs 4 ounces. During menstruation, the uterus can weigh as much as 8 ounces.”

between the urinary bladder and the rectum, the uterus is
the size and shape of an inverted pear.
In a female who has never been pregnant it is about 7.5 cm (3 in.) long, 5 cm (2 in.) wide, and 2.5 cm (1 in.)
thick. It is larger in females who have recently been pregnant and smaller (atrophied) when female sex
hormones levels are low, as occurs while taking birth control pills (see page 943) or after menopause (see page 946).”

is one of the earliest signs of puberty and generally precedes
menarche by 1 or 2 years. In 60 percent of girls,
the uterus reaches adult size by the 15th year. By this time a difference in proportion of length of the cervix to that of the fundus
becomes evident. In the newborn and prepuberal uterus, the relation of cervix to corpus is approximately 1 to 1.
However, in the adult this ratio becomes 1 to 2.”
the uterus is about 3 in. long. The size at the top measures
2.5 by 2 in. It narrows to a diameter of 1 in, measured
at the cervix. Recurrent pregnancies leave the uterus larger than in the nulliparous woman. After the menopause, shrinking and
atrophy progress. The senile uterus, with thinned out myometrium, often retrogresses to the size of the preadolescent stage.”

11.) National Uterine Fibroid Foundation. “The Uterus”.
‘normal’ uterus is typically the size and shape of an upside
and weighs somewhere around 6 ounces.
Its dimensional size is about 8-10 cm by 6 cm
(roughly 3-4 inches by 2 ½ inches).”
Gray (1821-1865). Anatomy of the Human Body. 1918. “3d.3. The Uterus”
“During menstruation the organ is enlarged, more vascular, and its surfaces rounder;
the external orifice is rounded, its labia swollen,
and the lining membrane of the body thickened, softer,
and of a darker color.”
“After parturition the uterus nearly
regains its usual size, weighing about 42 gm.;
but its cavity is larger than in the virgin state,
its vessels are tortuous, and its muscular layers are more defined;
the external orifice is more marked, and its edges present one or more fissures.”
