What Is an Imperforate Hymen?
The hymen refers to the thin membrane that covers a girl’s vaginal entrance. It is usually in the form of a half-moon, with enough room for menstrual blood to flow out of the opening of the vagina. However, this is not the case for an imperforate hymen.
In anatomical terms, imperforate translates to the absence of an opening that is supposed to be found in the body. As the name suggests, the membrane extension blocks the vaginal canal, leaving it with no available space to accommodate menstrual blood flow.
There are some cases wherein the hymen is slightly imperforate, which means that there is a small opening to the vagina. But extra tissue prevents it from being entirely accessible. The amount of blockage can vary depending from case to case.
An imperforate hymen is a congenital condition (from birth) that any girl at any age can have.
