The hymen is a thin piece of mucosal tissue that surrounds or partially covers the external vaginal opening. It forms part of the vulva, or external genitalia, and is similar in structure to the vagina.BOOK, Perlman, Sally E., Nakajyma, Steven T., Hertweck, S. Paige, Clinical protocols in pediatric and adolescent gynecology, 2004, Parthenon, 131, 978-1-84214-199-1, The hymen does not seem to have a specific physiological function and has few, if any, nerve endings.BOOK,weblink Virgin: The Untouched History, Blank, Hanne, Bloomsbury USA, 2008, 978-1-59691-011-9, 35, In children, a common appearance of the hymen is crescent-shaped, although many shapes are possible.During puberty, estrogen causes the hymen to change in appearance and become very elastic. Normal variations of the post-pubertal hymen range from thin and stretchy to thick and somewhat rigid; or it may instead be completely absent.The hymen may rip or tear the first time penetrative intercourse happens, which may cause temporary bleeding or slight discomfort, but sources differ on how common tearing and bleeding after first intercourse is.JOURNAL, Rogers, Deborah J, Stark, Margaret, 1998-08-08, The hymen is not necessarily torn after sexual intercourse, BMJ : British Medical Journal, 317, 7155, 414, 0959-8138, 1113684, 9694770, 10.1136/bmj.317.7155.414, JOURNAL, Emma Curtis, Camille San Lazaro, 1999-02-27, Appearance of the hymen in adolescents is not well documented, BMJ : British Medical Journal, en, 318, 7183, 605, We agree with Rogers and Stark that so called rupture and bleeding of the hymen is not to be routinely expected after first sexual intercourse., 1115047, 10037658, 10.1136/bmj.318.7183.605, The state of the hymen is not a reliable indicator of virginity, although it continues to be considered so in certain cultures, and virginity testing may be done. Minor injuries to the hymen may healJOURNAL, Hegazy, Abdelmonem, Al-Rukban, Mohammed, 2012-01-01, Hymen: Facts and conceptions,weblink TheHealth, en, 3, 4, 2219-8083, Possible explanations for the lack of genital trauma include... acute injuries occur but heal completely., without visible signs of previous injury. A torn hymen may be surgically restored in a procedure called hymenorrhaphy.

Development and histology

The genital tract develops during embryogenesis, from the third week of gestation to the second trimester, and the hymen is formed following the vagina. At week seven, the urorectal septum forms and separates the rectum from the urogenital sinus. At week nine, the Müllerian ducts move downwards to reach the urogenital sinus, forming the uterovaginal canal and inserting into the urogenital sinus. At week twelve, the Müllerian ducts fuse to create a primitive uterovaginal canal called unaleria. At month five, the vaginal canalization is complete and the fetal hymen is formed from the proliferation of the sinovaginal bulbs (where Müllerian ducts meet the urogenital sinus), and normally becomes perforate before or shortly after birth.BOOK, Healey, Andrew, Mann, Gurdeep S., Blair, Joanne C., Garden, Anne S., Imaging of Gynecological Disorders in Infants and Children, Springer, 2012, 21–30, Embryology of the female reproductive tract, 978-3-540-85602-3, 10.1007/978-3-540-85602-3, Medical Radiology, The hymen has no nerve innervation. In newborn babies, still under the influence of the mother's hormones, the hymen is thick, pale pink, and redundant (folds in on itself and may protrude). For the first two to four years of life, the infant produces hormones that continue this effect.McCann, J; Rosas, A. and Boos, S.

File:Carunculae myrtiformes.png|Arrows point to carunculae myrtiformes ("remnants") of the hymen in a post-pubertal individual.The hymen can stretch or tear as a result of various behaviors, by tampon or menstrual cup use, pelvic examinations with a speculum, regular physical activity, sexual intercourse, insertion of multiple fingers or items into the vagina, and activities such as gymnastics (doing 'the splits'), or horseback riding. Remnants of the hymen are called carunculae myrtiformes.BOOK, Knight, Bernard, Simpson's Forensic Medicine, 11th, 1997, Arnold, London, 114, 978-0-7131-4452-9, A glass or plastic rod of 6 mm diameter having a globe on one end with varying diameter from 10 to 25 mm, called a Glaister Keen rod, is used for close examination of the hymen or the degree of its rupture. In forensic medicine, it is recommended by health authorities that a physician who must swab near this area of a prepubescent girl avoid the hymen and swab the outer vulval vestibule instead. In cases of suspected rape or child sexual abuse, a detailed examination of the hymen may be performed, but the condition of the hymen alone is often inconclusive.

Anatomic variations

(File:Hymen en.svg|thumb|Various types of hymen (the dark areas represent the vaginal opening))Normal variations of the hymen range from thin and stretchy to thick and somewhat rigid; or it may also be completely absent.BOOK,weblink Evaluation of the Sexually Abused Child: A Medical Textbook and Photographic Atlas, 2000, Oxford University Press, 9780195074253, Heger, Astrid H., 2nd, New York, 61–65, English, Emans, S. Jean, An imperforate hymen occurs in 1-2 out of 1,000 infants.BOOK,weblink Blueprints Obstetrics and Gynecology, Callahan, Tamara L., Caughey, Aaron B., 2009, Lippincott Williams & Wilkins, 9780781782494, en, JOURNAL, Lardenoije, Céline, Aardenburg, Robert, Mertens, Helen, 2009-05-26, Imperforate hymen: a cause of abdominal pain in female adolescents, BMJ Case Reports, 2009, bcr0820080722, 10.1136/bcr.08.2008.0722, 1757-790X, 3029536, 21686660, The only variation that may require medical intervention is the imperforate hymen, which either completely prevents the passage of menstrual fluid or slows it significantly. In either case, surgical intervention may be needed to allow menstrual fluid to pass or intercourse to take place at all.Prepubescent girls' hymenal openings come in many shapes, depending on hormonal and activity level, the most common being crescentic (posterior rim): no tissue at the 12 o'clock position; crescent-shaped band of tissue from 1–2 to 10–11 o'clock, at its widest around 6 o'clock. From puberty onwards, depending on estrogen and activity levels, the hymenal tissue may be thicker, and the opening is often fimbriated or erratically shaped. In younger children, a torn hymen will typically heal very quickly. In adolescents, the hymenal opening can naturally extend and variation in shape and appearance increases.Variations of the female reproductive tract can result from agenesis or hypoplasia, canalization defects, lateral fusion and failure of resorption, resulting in various complications.WEB,weblink Imperforate Hymen, 2009-02-02, Different normal variants in hymenal configuration are described, varying from the common annular, to crescentic, to navicular ("boatlike" with an anteriorly displaced hymenal orifice). Hymenal variations are rarely clinically significant before menarche. In the case of a navicular configuration, urinary complaints (e.g., dribbling, retention, urinary tract infections) may result. Sometimes, a cribriform (fenestrated), septate, or navicular configuration to the hymen can be associated with retention of vaginal secretions and prolongation of the common condition of a mixed bacterial vulvovaginitis., WebMD,

  • Septate: the hymenal opening has one or more bands of tissue extending across the opening.


Historically, it was believed that first sexual intercourse was necessarily traumatic to the hymen and always resulted in the hymen being "broken" or torn, causing bleeding. However, research on women in Western populations has found that bleeding during first consensual intercourse does not always happen or is less common than not bleeding.NEWS,weblink Over het zwaard en de schede; bloedverlies en pijn bij de eerste coïtus Een onderzoek bij vrouwen uit diverse culturen, Loeber, Olga, 2008, Tijdschrift voor Seksuologie, 2018-09-07, 32, 129–137, nl-nl, In one cross-cultural study, slightly more than half of all women self-reported bleeding during first intercourse, with significantly different levels of pain and bleeding reported depending on their region of origin.JOURNAL, Amy, Jean-Jacques, January 2008, Certificates of virginity and reconstruction of the hymen, The European Journal of Contraception & Reproductive Health Care, en, 13, 2, 111–113, 10.1080/13625180802106045, 18465471, 1362-5187, In several studies of adolescent female rape victims, where patients were examined at a hospital following sexual assault, half or fewer of virgin victims had any injury to the hymen.JOURNAL, White, C., & McLean, I., 2006-05-01, Adolescent complainants of sexual assault; injury patterns in virgin and non-virgin groups, Journal of Clinical Forensic Medicine, en, 13, 4, 172–180, 10.1016/j.jcfm.2006.02.006, 16564196, 1353-1131, Hymen injury was noted in 40 (50.6%) participants of the virgin group, but only 11 (12.4%) of the non-virgin group, JOURNAL, Adams, Joyce A., Girardin, Barbara, Faugno, Diana, May 2000, Signs of genital trauma in adolescent rape victims examined acutely,weblink Journal of Pediatric and Adolescent Gynecology, English, 13, 2, 88, 10.1016/S1083-3188(00)00015-2, 1083-3188, JOURNAL, 2001-11-01, Adolescent Sexual Assault: Documentation of Acute Injuries Using Photo-colposcopy, Journal of Pediatric and Adolescent Gynecology, en, 14, 4, 175–180, 10.1016/S1083-3188(01)00126-7, 1083-3188, The incidence of hymenal tears in self-described virgins was higher than in nonvirgins (19% vs. 3%, P .008);, Adams, Joyce A., Girardin, Barbara, Faugno, Diana, Tears of the hymen occurred in less than a quarter of cases. However, virgins were significantly more likely to have injuries to the hymen than non-virgins.In a study of adolescents who had previously had consensual sex, approximately half showed evidence of trauma to the hymen.JOURNAL, Adams, Joyce A., Botash, Ann S., Kellogg, Nancy, March 2004, Differences in hymenal morphology between adolescent girls with and without a history of consensual sexual intercourse, Archives of Pediatrics & Adolescent Medicine, 158, 3, 280–285, 10.1001/archpedi.158.3.280, 1072-4710, 14993089, Subjects who admitted having past intercourse still had non disrupted, intact hymens in 52% of cases., WEB,weblink New York Times Is Wrong about Hymens--But They Are Not Alone, Psychology Today, en-GB, 2018-09-08, Trauma to the hymen may also occur in adult non-virgins following consensual sex, although it is rare.JOURNAL, Slaughter, Laura, Brown, Carl R.V., Crowley, Sharon, Peck, Roxy, March 1997, Patterns of genital injury in female sexual assault victims, American Journal of Obstetrics and Gynecology, 176, 3, 609–616, 10.1016/s0002-9378(97)70556-8, 9077615, 0002-9378, Trauma to the hymen may heal without any visible sign of injury.

The final ‘width’ of a hymenal rim was dependent on the initial depth of the laceration. No scar tissue formation was observed in either group of girls., Trauma to the hymen is hypothesized to occur as a result of various other behaviors, such as tampon or menstrual cup use, pelvic examinations with a speculum, masturbation, gymnastics, or horseback riding, although the true prevalence of trauma as a result of these activities is unclear.JOURNAL, 1998-06-08, Can tampon use cause hymen changes in girls who have not had sexual intercourse?

There was also no relation to prior gynecologic examination., Emans, S.Jean, Woods, Elizabeth R., Allred, Elizabeth N., Grace, Estherann,

Cultural significance

The hymen is often attributed important cultural significance in certain communities because of its association with a woman's virginity.WEB,weblink The Hymen, University of California, Santa Barbara, 2009-02-09, The hymen oftentimes, though not always, rips or tears the first time a female engages in penetrative intercourse, which may cause some temporary bleeding and slight discomfort., In those cultures, an intact hymen is highly valued at marriage in the belief that this is a proof of virginity.NEWS,weblink Muslim women in France regain virginity in clinics, Reuters, 'Many of my patients are caught between two worlds,' said Abecassis. They have had sex already but are expected to be virgins at marriage according to a custom that he called 'cultural and traditional, with enormous family pressure'., April 30, 2007, Some women undergo hymenorrhaphy to restore their hymen for this reason.NEWS, In Europe, Debate Over Islam and Virginity,weblink 'In my culture, not to be a virgin is to be dirt,' said the student, perched on a hospital bed as she awaited surgery on Thursday. 'Right now, virginity is more important to me than life.', The New York Times, June 11, 2008, 2008-06-13, Elaine, Sciolino, Souad, Mekhennet, In October 2018, the UN Human Rights, UN Women and the World Health Organization (WHO) stated that virginity testing must end as it is a painful, humiliating and traumatic practice, constituting violence against women.WEB,weblink United Nations agencies call for ban on virginity testing, 17 October 2018, World Health Organization, 22 October 2018,

Womb fury

In the 16th and 17th centuries, medical researchers mistakenly saw the presence or absence of the hymen as founding evidence of physical diseases such as "womb-fury", i.e., (female) hysteria. If not cured, womb-fury would, according to doctors practicing at the time, result in death.Berrios GE, Rivière L. (2006) 'Madness from the womb'. History of Psychiatry. 17:223-35.The linkage between the hymen and social elements of control has been taken up in Marie Loughlin's book Hymeneutics: Interpreting Virginity on the Early Modern Stage published in 1997

Other animals

Due to similar reproductive system development, many mammals have hymens, including chimpanzees, elephants, manatees, whales, horses and llamas.BOOK, Blank, Hanne, Hanne Blank,weblink Virgin: The Untouched History, 2007, Bloomsbury Publishing, 23, 978-1-59691-010-2, 2013-11-09, BOOK, Blackledge, Catherine, The Story of V, 2004, Rutgers University Press, Hymens, or vaginal closure membranes or vaginal constrictions, as they are often referred to, are found in a number of mammals, including llamas, ...,weblink 978-0-8135-3455-8,
