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.

For example, during the fertile years of a woman's reproductive cycle, females tend to have a larger cervix in comparison to postmenopausal females; likewise, females who have produced offspring have a larger sized cervix than females who have not produced offspring.

The fetus begins to lose the support of the cervix when contractions begin. With cervical dilation reaching 10 cm to accommodate the head of the fetus, the head moves from the uterus to the vagina. [82] [88] The elasticity of the vagina allows it to stretch to many times its normal diameter in order to deliver the child. [89]
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.
A Cochrane review in 2017 found that there was too little evidence to show whether X-ray pelvimetry is beneficial and safe when the baby is in cephalic presentation.

The average American woman will reach menopause at age 52, but onset age can range from about 45 to 58, per the Office on Women’s Health in the U.S. Department of Health and Human Services.
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.
“A double cervix or double uterus is way under 1%, maybe three per 1,000 women might have that,” Dr. Richard Davis, who specializes in high-risk pregnancies, explained.
