Calendar-based methods are various methods of estimating a woman's likelihood of fertility, based on a record of the length of previous menstrual cycles. Various methods are known as the Knaus–Ogino method and the rhythm method. The standard days method is also considered a calendar-based method, because when using it, a woman tracks the days of her menstrual cycle without observing her physical fertility signs. The standard days method is based on a fixed formula taking into consideration the timing of ovulation, the functional life of the sperm and the ovum, and the resulting likelihood of pregnancy on particular days of the menstrual cycle. These methods may be used to achieve pregnancy by timing unprotected intercourse for days identified as fertile, or to avoid pregnancy by avoiding unprotected intercourse during fertile days.
Menstruation is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels and is a sign that pregnancy has not occurred.
The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that make pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the uterus (womb) to receive a fertilized egg. These cycles are concurrent and coordinated, normally last between 21 and 35 days in adult women, with a median length of 28 days, and continue for about 30–45 years.
Menarche is the first menstrual cycle, or first menstrual bleeding, in female humans. From both social and medical perspectives, it is often considered the central event of female puberty, as it signals the possibility of fertility.
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. However, in addition to menstrual blood, the tampon also absorbs the vagina's natural lubrication and bacteria, which can change the normal pH, increasing the risk of infections from the bacterium Staphylococcus aureus, which can lead to toxic shock syndrome (TSS). TSS is a rare but life-threatening infection that requires immediate medical attention.
Niddah, in traditional Judaism, describes a woman who has experienced a uterine discharge of blood, or a woman who has menstruated and not yet completed the associated requirement of immersion in a mikveh.
A sanitary napkin, sanitary towel, sanitary pad, menstrual pad, or pad is an absorbent item worn by women in their underwear when menstruating, bleeding after giving birth, recovering from gynecologic surgery, experiencing a miscarriage or abortion, or in any other situation where it is necessary to absorb a flow of blood from the vagina. A menstrual pad is a type of menstrual hygiene product that is worn externally, unlike tampons and menstrual cups, which are worn inside the vagina. Pads are generally changed by being stripped off the pants and panties, taking out the old pad, sticking the new one on the inside of the panties and pulling them back on. Pads are recommended to be changed every 3–4 hours to avoid certain bacteria that can fester in blood, this time also may differ depending on the kind worn, flow, and the time it is worn.
Menstrual synchrony, also called the McClintock effect, is an alleged process whereby women who begin living together in close proximity experience their menstrual cycle onsets becoming more synchronized together in time than when previously living apart. "For example, the distribution of onsets of seven female lifeguards was scattered at the beginning of the summer, but after 3 months spent together, the onset of all seven cycles fell within a 4-day period."
A menstrual disorder is characterized as any abnormal condition with regards to a person's menstrual cycle. There are many different types of menstrual disorders that vary with signs and symptoms, including pain during menstruation, heavy bleeding, or absence of menstruation. Normal variations can occur in menstrual patterns but generally menstrual disorders can also include periods that come sooner than 21 days apart, more than 3 months apart, or last more than 10 days in duration. Variations of the menstrual cycle are mainly caused by the immaturity of the hypothalamic-pituitary-ovarian (HPO) axis, and early detection and management is required in order to minimize the possibility of complications regarding future reproductive ability.
Cloth menstrual pads are cloth pads worn in the underwear to collect menstrual fluid. They are a type of reusable menstrual hygiene product, and are an alternative to disposable sanitary napkins or to menstrual cups. Because they can be reused, they are generally less expensive than disposable pads over time, and reduce the amount of waste produced.
Culture and menstruation is about cultural aspects surrounding how societies view menstruation. A menstrual taboo is any social taboo concerned with menstruation. In some societies it involves menstruation being perceived as unclean or embarrassing, inhibiting even the mention of menstruation whether in public or in private. Many traditional religions consider menstruation ritually unclean, although anthropologists point out that the concepts 'sacred' and 'unclean' may be intimately connected.
Martha Kent McClintock is an American psychologist best known for her research on human pheromones and her theory of menstrual synchrony.
Clelia Duel Mosher was a physician, hygienist and women's health advocate who disapproved of Victorian stereotypes about the physical incapacities of women.
Kathleen O'Grady is a Canadian author and academic. She has published two children's books, but is more widely known as a feminist scholar who investigates women's health issues through a cultural lens and whose work addresses the under-researched intersection between feminism and the study of religion. She is also a past Editor of Network, the national, bilingual health magazine for Canadian women, and has published several books addressing feminist theory and methodology.
Nancy Fugate Woods is emerita professor in Biobehavioral Nursing and Health Informatics at the University of Washington. She previously served as the dean of the University of Washington's nursing program and as the president of the American Academy of Nursing.
The ḥaiḍ is the religious state of menstruation in Islam. Menstruation relates to various purity related restrictions in Islamic sexual jurisprudence.
A menstruation hut is a place of seclusion or isolation used by certain cultures with strong menstrual taboos. The same or a similar structure may be used for childbirth and postpartum confinement, based on beliefs around ritual impurity. These huts are usually built near the family home, have small doors, and are often dilapidated, with poor sanitation and ventilation, and no windows. The Nepali version, the Chhaupadi, is probably the best-known example, but cultural attitudes towards menstruation around the world mean that these huts exist, or existed until recently, in other places as well. The use of menstrual huts continues to be the cause of death, from exposure, dehydration, snake bite, smoke inhalation, and so on. The use of these huts is illegal in some places.
Sharra L. Vostral is a Professor of History and Science and Technology at the College of Liberal Arts at Purdue University. She has written two books about menstruation and history: Under Wraps: A History of Menstrual Hygiene Technology and Toxic Shock: A Social History.
Menstrual hygiene management (MHM) or menstrual health and hygiene (MHH) refers to access to menstrual hygiene products to absorb or collect the flow of blood during menstruation, privacy to change the materials, and access to facilities to dispose of used menstrual management materials. It can also include the "broader systemic factors that link menstruation with health, well-being, gender equality, education, equity, empowerment, and rights". Menstrual hygiene management can be particularly challenging for girls and women in developing countries, where clean water and toilet facilities are often inadequate. Menstrual waste is largely ignored in schools in developing countries, despite it being a significant problem. Menstruation can be a barrier to education for many girls, as a lack of effective sanitary products restricts girls' involvement in educational and social activities.
In Islam, the Istihadha represents a disturbance of the menstrual cycle of the woman which makes it difficult for her to perform some religious rituals (ibadah).
