MarriageMarriage, also called matrimony or wedlock, is a culturally and often legally recognized union between people called spouses. It establishes rights and obligations between them, as well as between them and their children (if any), and between them and their in-laws. It is nearly a cultural universal, but the definition of marriage varies between cultures and religions, and over time. Typically, it is an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned.
Youth suffrageYouth suffrage is the right of youth to vote and forms part of the broader universal suffrage and youth rights movements. Most democracies have lowered the voting age to between 16 and 18, while some advocates for children's suffrage hope to remove age restrictions entirely. Suffrage The "one man, one vote" democratic ideal supports giving voting rights to as many people as possible in order for the wisdom of a more representative electorate to create better outcomes for society.
Violence against menViolence against men is a term for violent acts that are disproportionately or exclusively committed against men or boys. Men are over-represented as both victims and perpetrators of violence. Studies of social attitudes show violence is perceived as more or less serious depending on the gender of victim and perpetrator. People are less likely to report a man hitting another man to the police than a man hitting a woman. Male law enforcement officers show a greater reluctance to file charges or reports when a man is the victim of domestic violence.
OvulationOvulation is the release of eggs from the ovaries. In women, this event occurs when the ovarian follicles rupture and release the secondary oocyte ovarian cells. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm. In addition, the uterine lining (endometrium) is thickened to be able to receive a fertilized egg. If no conception occurs, the uterine lining as well as the egg will be shed during menstruation. Ovulation occurs about midway through the menstrual cycle, after the follicular phase.
Menstrual cycleThe 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 makes 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 an embryo. These cycles are concurrent and coordinated, normally last between 21 and 35 days, with a median length of 28 days, and continue for about 30–45 years.
Civil marriageA civil marriage is a marriage performed, recorded, and recognized by a government official. Such a marriage may be performed by a religious body and recognized by the state, or it may be entirely secular. Every country maintaining a population registry of its residents keeps track of marital status, and all UN Member countries except Iran, Somalia, South Sudan, Sudan, and Tonga have signed or ratified either the United Nations Convention on Consent to Marriage, Minimum Age for Marriage, and Registration of Marriages (1962) or the United Nations Convention on the Elimination of All Forms of Discrimination against Women (1979) which carry a responsibility to register marriages.
Interfaith marriageInterfaith marriage, sometimes called a "mixed marriage", is marriage between spouses professing different religions. Although interfaith marriages are often established as civil marriages, in some instances they may be established as a religious marriage. This depends on religious doctrine of each of the two parties' religions; some prohibit interfaith marriage, and among others there are varying degrees of permissibility. Several major religions are mute on the issue, and still others allow it with requirements for ceremony and custom.
Morganatic marriageMorganatic marriage, sometimes called a left-handed marriage, is a marriage between people of unequal social rank, which in the context of royalty or other inherited title prevents the principal's position or privileges being passed to the spouse, or any children born of the marriage. The concept is most prevalent in German-speaking territories and countries most influenced by the customs of the German-speaking realms.
Christian views on marriageFrom the earliest days of the Christian faith, Christians have viewed marriage as a divinely blessed, lifelong, monogamous union between a man and a woman. However, while many Christians might agree with the traditional definition, the terminology and theological views of marriage have varied through time in different countries, and among Christian denominations. Many Protestants consider marriage to be a sacred institution or "holy ordinance" of God. Catholic and Eastern Orthodox Christians consider marriage as a holy sacrament or sacred mystery.
HealthIn common usage and medicine, health, according to the World Health Organization, is "a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity". A variety of definitions have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress.
Fertility testingFertility testing is the process by which fertility is assessed, both generally and also to find the "fertile window" in the menstrual cycle. General health affects fertility, and STI testing is an important related field. Healthy women are fertile from puberty until menopause, although fertility is typically much reduced towards the extremes of this period. The onset of puberty is typically identified by menarche and the presence of secondary sexual characteristics such as breast development, the appearance of pubic hair and changes to body fat distribution.
