Question: what is the average size of a woman's cervix?
Answer: The cervix is the lower narrower portion of the uterus. The cervix or cervix uteri (Latin, 'neck of the uterus') is the lower part of the uterus in the human female reproductive system. The cervix is usually 2 to 3 cm long (~1 inch) and roughly cylindrical in shape, which changes during pregnancy.
