Types
What Are the main Different Types of Hymen
Imperforate Hymen
A condition in which the hymen fails to open up and therefore completely covers the opening to the vagina, blocking menstrual blood and secretions from flowing out. An imperforate hymen may be noted at birth, but more commonly is diagnosed during puberty. An adolescent girl with an imperforate hymen typically presents with no menstrual period and abdominal or pelvic pain. This is due to the vagina being filled with menstrual blood that cannot exit. The patient may also have urinary symptoms - such as urinary frequency, urinary urgency, or feelings of incomplete voiding.
Microperforate Hymen
A condition in which the hymen has a very small opening. Menstrual blood and vaginal secretions can flow out of the vagina, but the patient may have difficulty or inability to use tampons or have vaginal intercourse. In some cases, a teen with a microperforate hymen may not realize that she has a very small opening. If she is able to place a tampon into her vagina, she may not be able to remove it when it becomes filled with blood.
Cribiform Hymen
A condition in which the hymen has several very small openings. Menstrual blood and vaginal secretions can flow out of the vagina, but the patient will be unable to use tampons or have vaginal intercourse.
Septate Hymen
A septate hymen occurs when the hymen has a band of extra tissue in the middle that causes two small vaginal openings instead of one. Menstrual blood and vaginal secretions can flow out of the vagina, but the patient may have difficulty or inability to use tampons or have vaginal intercourse. In some cases, a teen with a septate hymen may not realize that she has extra tissue. If she is able to place a tampon into her vagina, she may not be able to remove it when it becomes filled with blood
Dilatable hymen
It does not tear during intercourse, and therefore there is no blood after intercourse, as it is very flexible.
