The uterus (from Latin uterus, pl.: uteri or uteruses) or womb (/ w uː m /) is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more fertilized eggs until birth. [1]
The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
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.
A second study by the same group showed significant variations in size and shape between the vaginas of women of different ethnic groups. [4] Both studies showed a wide range of vaginal shapes, described by the researchers as "Parallel sided, conical, heart, [...] slug" [3] and "pumpkin seed" [4] shapes. Barnhart et al., however, were not able ...
During development, the outer parts of the two ducts fuse, forming a single urogenital canal that will become the vagina, cervix and uterus. [14] The cervix grows in size at a smaller rate than the body of the uterus, so the relative size of the cervix over time decreases, decreasing from being much larger than the body of the uterus in fetal ...
In 2019, a woman living in Bangladesh with a double uterus gave birth to three babies — first, a baby from one uterus, and then, 26 days later, twins from her second uterus.
“Patient height, weight, uterine size and anatomy all play a role,” Thiel explained. “Also the position of the baby and the position of the uterus itself can change how a pregnancy is carried.
In females, the uterus, fallopian tubes, ovaries and upper vagina occupy the area between the other viscera. [1] [2] The rectum is located at the back of the pelvis, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. The pelvic cavity also contains major arteries, veins, muscles, and nerves.
