Male Infertility Crisis
The male infertility crisis is an increase in male infertility since the mid-1970s. The issue attracted media attention after a 2017 meta-analysis found that sperm counts had declined by 52.4 percent between 1973 and 2011. The decline is particularly prevalent in Western countries such as New Zealand and Australia, Europe and North America. A 2022 meta-analysis reported that this decline extends to non-Western countries, namely those in Asia, Africa, Central America, and South America. This meta-analysis also suggests that the decline in sperm counts may be accelerating. This decline in male fertility is the subject of research and debate. Proposed explanations include lifestyle factors, such as changes in diet and physical activity levels, and increased exposure to endocrine disrupting chemicals, such as those found in plastics. Some scientists have questioned the extent of the crisis, saying that sperm-count studies are geographically sparse, often fail to account for a subje ...

Male Infertility
Male infertility refers to a sexually mature male's inability to impregnate a fertile female. In humans it accounts for 40–50% of infertility. It affects approximately 7% of all men. Male infertility is commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity. More recently, advance sperm analyses that examine intracellular sperm components are being developed. Age considerations There is a decrease in sperm concentration as men age: 90% of seminiferous tubules in men in their 20s and 30s contain spermatids, whereas men in their 40s and 50s have spermatids in 50% of their seminiferous tubules, and only 10% of seminiferous tubules from men aged > 80 years contain spermatids. In a random international sample of 11,548 men confirmed to be biological fathers by DNA paternity testing, the oldest father was found to be 66 years old at the birth of his child; the ratio of DNA-confirmed versus DNA-rejected paternity tests around that ag ...

Social Commentator
Social commentary is the act of using rhetorical means to provide commentary on social, cultural, political, or economic issues in a society. This is often done with the idea of implementing or promoting change by informing the general populace about a given problem and appealing to people's sense of justice. Social commentary can be practiced through all forms of communication, from printed form, to conversations to computerized communication. Two examples of strong and bitter social commentary are the writings of Anglo-Irish writer Jonathan Swift and German priest Martin Luther. Swift decried the appalling conditions faced by Irish Catholics under the rule of the Protestant Ascendancy in ''A Modest Proposal'', while Martin Luther decried corruption in the Catholic Church in his ''Ninety-five Theses. Examples of social commentators from the lower social strata are Charles Dickens and Will Rogers. Forms This list is far from exhaustive. Examples of social commentary may be found ...

Father
A father is the male parent of a child. Besides the paternal bonds of a father to his children, the father may have a parental, legal, and social relationship with the child that carries with it certain rights and obligations. An adoptive father is a male who has become the child's parent through the legal process of adoption. A biological father is the male genetic contributor to the creation of the infant, through sexual intercourse or sperm donation. A biological father may have legal obligations to a child not raised by him, such as an obligation of monetary support. A putative father is a man whose biological relationship to a child is alleged but has not been established. A stepfather is a male who is the husband of a child's mother and they may form a family unit, but who generally does not have the legal rights and responsibilities of a parent in relation to the child. The adjective "paternal" refers to a father and comparatively to "maternal" for a mother. The verb "to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marriage
Marriage, 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, and between them and their in-laws. It is considered 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. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity. A marriage ceremony is called a wedding. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, and religious purposes. Whom they marry may be influenced by gender, socially determined rules of incest, prescriptive marriage rules, parental choice, and individual desire. In some areas of the world, arrang ...

Recreational Drug Use
Recreational drug use indicates the use of one or more psychoactive drugs to induce an altered state of consciousness either for pleasure or for some other casual purpose or pastime by modifying the perceptions and emotions of the user. When a psychoactive drug enters the user's body, it induces an intoxicating effect. Generally, recreational drugs are divided into three categories: depressants (drugs that induce a feeling of relaxation and calmness); stimulants (drugs that induce a sense of energy and alertness); and hallucinogens (drugs that induce perceptual distortions such as hallucination). In popular practice, recreational drug use generally is a tolerated social behaviour, rather than perceived as the medical condition of self-medication. However, heavy use of some drugs is socially stigmatized. Many people also use prescribed and controlled depressants such as opioids, as well as opiates and benzodiazepines. Common recreational drugs include caffeine, commonly foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Behaviour
Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone (e.g., masturbation) to acts with another person (e.g., sexual intercourse, non-penetrative sex, oral sex, etc.) in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners (courtship and display behaviour), or personal interactions between individuals (for instance, foreplay or BDSM). Sexual activity may follow sexual arousal. Human sexual activity has sociological, cognitive, emotional, behavioural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sampling Bias
In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others. It results in a biased sample of a population (or non-human factors) in which all individuals, or instances, were not equally likely to have been selected. If this is not accounted for, results can be erroneously attributed to the phenomenon under study rather than to the method of sampling. Medical sources sometimes refer to sampling bias as ascertainment bias. Ascertainment bias has basically the same definition, but is still sometimes classified as a separate type of bias. Distinction from selection bias Sampling bias is usually classified as a subtype of selection bias, sometimes specifically termed sample selection bias, but some classify it as a separate type of bias. A distinction, albeit not universally accepted, of sampling bias is that it undermines the external validity of a test (the ...

Semen Quality
Semen quality is a measure of male fertility, a measure of the ability of sperm in semen to accomplish fertilization. Semen quality involves both sperm quantity and quality Cryptorchidism, hypospadias, testicular cancer and poor semen quality make up the syndrome known as testicular dysgenesis syndrome. Factors There are many factors that influence the sperm quality. Exposure to any of the temporary factors can cause up to a three-month delay before sperm quality returns to normal, due to spermiogenesis. General decline A 2017 review and meta-analysis found sperm counts among Western men (i.e. men in Australia, Europe, New Zealand, and North America) declined 50–60% between 1973 and 2011, with an average decline of 1.4% per year. The meta-analysis found no indication the decline is leveling off. The amount of decline among men in North America and men in Australia/Europe is similar. The decline in sperm count among men in South America, Asia, and Africa is less than men in W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Handmaid's Tale
''The Handmaid's Tale'' is a futuristic dystopian novel by Canadian author Margaret Atwood and published in 1985. It is set in a near-future New England in a patriarchal, totalitarian theonomic state known as the Republic of Gilead, which has overthrown the United States government. Offred is the central character and narrator and one of the "handmaids", women who are forcibly assigned to produce children for the "commanders", who are the ruling class in Gilead. The novel explores themes of subjugated women in a patriarchal society, loss of female agency and individuality, suppression of women's reproductive rights, and the various means by which women resist and try to gain individuality and independence. The title echoes the component parts of Geoffrey Chaucer's ''The Canterbury Tales'', which is a series of connected stories (such as "The Merchant's Tale" and "The Parson's Tale"). It also alludes to the tradition of fairy tales where the central character tells her story. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Children Of Men
''Children of Men'' is a 2006 dystopian action thriller film co-written and directed by Alfonso Cuarón. The screenplay, based on P. D. James' 1992 novel '' The Children of Men'', was credited to five writers, with Clive Owen making uncredited contributions. The film takes place in 2027, when two decades of human infertility have left society on the brink of collapse.

Dystopian Fiction
Utopian and dystopian fiction are genres of speculative fiction that explore social and political structures. Utopian fiction portrays a setting that agrees with the author's ethos, having various attributes of another reality intended to appeal to readers. Dystopian fiction offers the opposite: the portrayal of a setting that completely disagrees with the author's ethos. Some novels combine both genres, often as a metaphor for the different directions humility can take depending on its choices, ending up with one of two possible futures. Both utopias and dystopias are commonly found in science fiction and other types of speculative fiction. More than 400 utopian works in the English language were published prior to the year 1900, with more than a thousand others appearing during the 20th century. This increase is partially associated with the rise in popularity of genre fiction, science fiction and young adult fiction more generally, but also larger scale social change that broug ...

Clickbait
Clickbait is a text or a thumbnail link that is designed to attract attention and to entice users to follow that link and read, view, or listen to the linked piece of online content, being typically deceptive, sensationalized, or otherwise misleading. A "teaser" aims to exploit the "curiosity gap", providing just enough information to make readers of news websites curious, but not enough to satisfy their curiosity without clicking through to the linked content. Clickbait headlines often add an element of dishonesty, using enticements that do not accurately reflect the content being delivered. The "-bait" part of the term makes an analogy with fishing, where a hook is disguised by an enticement ( bait), presenting the impression to the fish that it is a desirable thing to swallow. Before the Internet, a marketing practice known as bait-and-switch used similar dishonest methods to hook customers. In extreme degree, like bait-and-switch, clickbait is a form of fraud.
