Hymen
The hymen is a thin piece of mucosal tissue that surrounds or partially covers the vaginal opening. A small percentage of females 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. The word is from the Greek ''ὑμήν'' meaning a thin skin or 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. Normal variations of the post-pubertal hymen range from thin and stretchy to thick and somewhat rigid. Very rarely, it may be completely absent. 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. His ...

Hymenorrhaphy
Hymenorrhaphy or "hymen reconstruction surgery" is the surgical alteration of the hymen, with the goal of producing bleeding on intercourse and a tight vaginal introitus, falsely believed to indicate virginity. The term comes from the Greek words ''hymen'' meaning "membrane", and ''raphḗ'' meaning " suture". It is also known as ''hymenoplasty'', although strictly this term would also include hymenotomy. The normal aim is to cause bleeding during post-nuptial intercourse, which in some cultures is wrongly considered proof of virginity. Roughly half of women having vaginal intercourse for the first time do not bleed; a small study found that of 19 women who underwent hymenorrhaphy and attended follow-up, 17 did not have bleeding at the next intercourse. It is also based on the false belief that there are "intact" and "broken" hymens, distinct in appearance or feel. It is not possible to determine whether someone is a virgin by the appearance of their hymen or the tightness of ...

Imperforate Hymen
An imperforate hymen is a congenital disorder where a hymen without an opening completely obstructs the vagina. It is caused by a failure of the hymen to perforate during fetal development. It is most often diagnosed in adolescent girls when menstrual blood accumulates in the vagina and sometimes also in the uterus. It is treated by surgical incision of the hymen. Signs and symptoms Affected newborns may present with acute urinary retention. In adolescent females, the most common symptoms of an imperforate hymen are cyclic pelvic pain and amenorrhea; other symptoms associated with hematocolpos include urinary retention, constipation, low back pain, nausea, and diarrhea. Other vaginal anomalies can have similar symptoms to an imperforate hymen. Vaginal atresia and a transverse vaginal septum require differentiation. A strong urge to defecate has been observed in a few women. Complications If untreated or unrecognized before puberty, an imperforate hymen can lead to peritonitis ...

Virginity
Virginity is a social construct that denotes the state of a person who has never engaged in sexual intercourse. As it is not an objective term with an operational definition, social definitions of what constitutes virginity, or the lack thereof, vary. Heterosexuals may or may not consider loss of virginity to occur only through penile–vaginal penetration, while people of other sexual orientations often include oral sex, anal sex, or manual sex in their definitions of virginity loss. The term "virgin" encompasses a range of definitions, as found in traditional, modern, and ethical concepts. Religious rituals for regaining virginity exist in many cultures. Some men and women who practice celibacy after losing their virginity consider themselves born-again virgins. There are cultural and religious traditions that place special value and significance on this state, predominantly towards unmarried females, associated with notions of personal purity, honour, and worth. Like c ...

Virginity Test
A virginity test is the pseudoscientific practice and process of determining whether a woman or girl is a virgin; i.e., to determine that she has never engaged in, or been subjected to, vaginal intercourse. The test typically involves a check for the presence of an intact hymen, typically on the flawed assumption that it can only be, and will always be torn as a result of vaginal intercourse. Virginity testing is most common in Asia and the Middle East, as well as Northern and Southern Africa and in Europe. Virginity testing is widely considered controversial because of its implications for the tested women and girls as it is viewed as unethical, and because such tests are widely considered to be unscientific. In cases of suspected rape, child sexual abuse, or other forms of sexual assault, a detailed examination of the hymen may be performed, but the condition of the hymen alone is often inconclusive. In October 2018, the UN Human Rights Council, UN Women and the World Health Or ...

Menstrual Cup
A menstrual cup is a feminine hygiene, menstrual hygiene device which is inserted into the vagina during menstruation. Its purpose is to collect menstrual fluid (blood from the uterine lining mixed with other fluids)Menstrual cupsare made of elastomers (silicone rubbers, latex rubbers, or thermoplastic rubbers). A properly fitting menstrual cup seals against the vaginal walls, so tilting and handstand, inverting the body will not cause it to leak. It is impermeable and collects menstrual fluid, unlike tampons and menstrual pads, which absorb it.Elizabeth Gunther Stewart, Paula Spencer: ''The V Book: A Doctor's Guide to Complete Vulvovaginal Health'', Bantam Books, 2002, Seiten 96 und 97, . Menstrual cups come in two types. The older type is bell-shaped, often with a stem, and has walls more than 2mm thick. The second type has a springy rim, and attached to the rim, a bowl with thin, flexible walls. Bell-shaped cups sit over the cervix, like cervical caps, but they are generally ...

Vagina
In mammals and other animals, the vagina (: vaginas or vaginae) is the elastic, muscular sex organ, reproductive organ of the female genital tract. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The #Vaginal opening and hymen, vaginal introitus is normally partly covered by a thin layer of mucous membrane, mucosal tissue called the hymen. The vagina allows for Copulation (zoology), copulation and birth. It also channels Menstruation (mammal), menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, en ...

Along with pleasure and bonding, women's sexual behavior with other people ca ...

Tampon
A tampon is a menstrual product designed to absorb blood and vaginal secretions by insertion into the vagina during menstruation. Unlike a pad, it is placed internally, inside of the vaginal canal. Once inserted correctly, a tampon is held in place by the vagina and expands as it soaks up menstrual blood. As tampons also absorb the vagina's natural lubrication and bacteria in addition to menstrual blood, they can increase the risk of toxic shock syndrome by changing the normal pH of the vagina and increasing the risk of infections from the bacterium ''Staphylococcus aureus''. TSS is a rare but life-threatening infection that requires immediate medical attention. The majority of tampons sold are made of blends of rayon and cotton, along with synthetic fibers. Some tampons are made out of organic cotton. Tampons are available in several absorbency ratings. Several countries regulate tampons as medical devices. In the United States, they are considered to be a Class II medic ...

Vulva
In mammals, the vulva (: vulvas or vulvae) comprises mostly external, visible structures of the female sex organ, genitalia leading into the interior of the female reproductive tract. For humans, it includes the mons pubis, labia majora, labia minora, clitoris, vulval vestibule, vestibule, urinary meatus, vaginal introitus, hymen, and openings of the vestibular glands (Bartholin's gland, Bartholin's and Skene's gland, Skene's). The folds of the outer and inner labia provide a double layer of protection for the vagina (which leads to the uterus). Pelvic floor muscles support the structures of the vulva. Other muscles of the urogenital triangle also give support. Blood supply to the vulva comes from the three pudendal arteries. The internal pudendal veins give drainage. Lymphatic vessel#Afferent vessels, Afferent lymph vessels carry lymph away from the vulva to the inguinal lymph nodes. The nerves that supply the vulva are the pudendal nerve, perineal nerve, ilioinguinal nerve ...

Pelvic Examination
A pelvic examination is the physical examination of the external and internal female pelvic organs. It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract, such as pain, bleeding, discharge, urinary incontinence, or trauma (e.g. sexual assault). It can also be used to assess a woman's anatomy in preparation for procedures. The exam can be done awake in the clinic and emergency department, or under anesthesia in the operating room. The most commonly performed components of the exam are 1) the external exam, to evaluate the vulva 2) the internal exam with palpation (commonly called the ''bimanual exam'') to examine the uterus, ovaries, and structures adjacent to the uterus (adnexae) and 3) the internal exam using a speculum to visualize the vaginal walls and cervix. During the pelvic exam, sample of cells and fluids may be collected to screen for sexually transmitted infections or cancer (the Pap test). Some clinici ...

Development Of The Reproductive System
The development of the reproductive system is the part of embryonic growth that results in the sex organs and contributes to sexual differentiation. Due to its large overlap with development of the urinary system, the two systems are typically described together as the genitourinary system. The reproductive organs develop from the intermediate mesoderm and are preceded by more primitive structures that are superseded before birth. These embryonic structures are the mesonephric ducts (also known as ''Wolffian ducts'') and the paramesonephric ducts, (also known as ''Müllerian ducts''). The mesonephric duct gives rise to the male seminal vesicles, epididymides and vasa deferentia. The paramesonephric duct gives rise to the female fallopian tubes, uterus, cervix, and upper part of the vagina. Mesonephric ducts The mesonephric duct originates from a part of the pronephric duct. Origin In the outer part of the intermediate mesoderm, immediately under the ectoderm, in the re ...
