The hymen (also called maidenhead) is tissue that surrounds or partially covers the external vaginal opening. The hymen has no known use. People used to believe that the hymen always tears after having sexual intercourse for the first time, and that you could if a woman was virgin by looking at her hymen and seeing if it was torn. However, it turns out that it is impossible to tell if someone is a virgin by looking at their hymen. Some women are also born without a hymen.
There are several different types of hymen. In about 1 in 2,000 females, the hymen does not develop at all. The hymen may also not have a hole in it; this is called an "imperforate hymen". In this case a hole will need to be surgically cut into it to allow menstrual fluid (period blood) out.
Other types are:
- forming a ring around the vagina
- folding in on itself
- has one or more bands going across the opening
- has several holes

The stages of growthEdit
In young babies, the hymen is thick and pink. This is because the mother is giving the baby hormones through breast feeding which keeps it thick. In adolescent girls, the hymen becomes thin, smooth and delicate because she has stopped taking in hormones. The hymen becomes very sensitive and can easily cause pain if touched. From puberty, the hymen gets thicker again and becomes pale pink. This is because of the hormone estrogen.
