Anatomical terminology

The hymen is a thin piece of mucosal tissue that surrounds or partially covers the vaginal introitus. A small percentage are born with hymens that are imperforate and completely obstruct the vaginal canal. It forms part of the vulva and is similar in structure to the vagina.[1][2] The term comes straight from the Greek, for 'membrane'.

In children, a common appearance of the hymen is crescent-shaped, although many shapes are possible. Each shape in the natural range has a Latinate name. During puberty, estrogen causes the hymen to change in appearance and become very elastic.[3][4] Normal variations of the post-pubertal hymen range from thin and stretchy to thick and somewhat rigid.[1] Very rarely, it may be completely absent.[5]

The hymen can rip or tear during first penetrative intercourse, which usually results in pain and, sometimes, mild temporary bleeding or spotting. Minor injuries to the hymen may heal on their own, and not require surgical intervention.[6] Historically, it was believed that first penetration was necessarily traumatic, but now sources differ on how common tearing or bleeding are as a result of first intercourse.[7][8][9] Therefore, the state of the hymen is not a reliable indicator of virginity,[2][10] though "virginity testing" remains a common practice in some cultures, sometimes accompanied by hymen reconstruction surgery to give the appearance of virginity.

  7. ^ "The Hymen". University of California, Santa Barbara. Retrieved September 19, 2020. While some females bleed the first time they have penetrative intercourse, not every female does. This depends on many factors, such as how much hymenal tissue a female has, whether her hymen has already been stretched or torn, or how thick and elastic it is.

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.
