Where is the hymen located?

Patient's question:

No

Doctor's answer:

The hymen is a thin, hollow membrane covering the external opening of the female vagina, about 1-2 millimeters thick. The front and back surfaces of the membrane are moist mucous membranes, with connective tissue, small blood vessels, and nerve endings between the two layers of mucous membranes. There is a small opening in the middle called the hymen opening.
