Moggy Sybil a Internal Nature for Met Art X
A man is an adult male human.[1] [2] Prior to machismo, a male person human is referred to as a boy (a boy or adolescent). Like most other male person mammals, a man's genome commonly inherits an X chromosome from the female parent and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the evolution of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition.
Male beefcake is distinguished from female anatomy past the male person reproductive organization, which includes the penis, testicles, sperm duct, prostate gland and the epididymis, besides every bit secondary sexual practice characteristics.
Etymology and terminology
The English term "homo" is derived from the Proto-Indo-European root *human being- (see Sanskrit/Avestan manu-, Slavic mǫž "man, male").[3] More directly, the word derives from Former English mann. The Old English form primarily meant "person" or "human existence" and referred to men, women, and children alike. The Old English discussion for "human" every bit singled-out from "woman" or "child" was wer. Isle of mann simply came to mean "human" in Center English, replacing wer, which survives today merely in the compound "werewolf" (from Old English language werwulf, literally "human being-wolf").[four] [five]
Biology
In humans, sperm cells commonly carry either an X or a Y sexual activity chromosome. If a sperm cell carrying a Y chromosome fertilizes the female person ova, the offspring will be male (XY). The SRY cistron is ordinarily found on the Y chromosome and is the testis determining gene that governs male person sex activity differentiation. Sexual practice differentiation in males proceeds in a testes dependent fashion while female differentiation is not gonad dependent.[6]
Humans exhibit sexual dimorphism in many characteristics, many of which have no direct link to reproductive power, although most of these characteristics do have a role in sexual attraction. Almost expressions of sexual dimorphism in humans are constitute in height, weight, and body structure, though there are ever examples that do not follow the overall pattern. For example, men tend to be taller than women, simply in that location are many people of both sexes who are in the mid-pinnacle range for the species.
Master sexual practice characteristics (or sex organs) are characteristics that are nowadays at nativity and are integral to the reproductive process. For men, primary sex characteristics include the penis and testicles. Secondary sex characteristics are features that announced during puberty in humans.[seven] [8] Such features are peculiarly evident in the sexually dimorphic phenotypic traits that distinguish betwixt the sexes, simply—unlike the principal sex activity characteristics—are non directly part of the reproductive system.[nine] [10] [11] Secondary sexual characteristics that are specific to men include:
- Facial hair;[10]
- Chest hair;[12]
- Broadened shoulders;[13]
- An enlarged larynx (as well known equally an Adam'south apple tree);[xiii] and
- A voice that is significantly deeper than the vocalism of a child or a woman.[10]
Reproductive system
The male reproductive system includes external and internal genitalia. The male external genitalia consist of the penis, the male urethra, and the scrotum, while the male person internal genitalia consist of the testes, the prostate, the epididymis, the seminal vesicle, the vas deferens, the ejaculatory duct, and the bulbourethral gland.[fourteen]
The male reproductive arrangement's office is to produce semen, which carries sperm and thus genetic information that tin unite with an egg within a adult female. Since sperm that enters a woman'due south uterus and then fallopian tubes goes on to fertilize an egg which develops into a fetus or child, the male reproductive system plays no necessary role during the gestation. The study of male reproduction and associated organs is called andrology.
Sex hormones
Testosterone stimulates the development of the Wolffian ducts, the penis, and closure of the labioscrotal folds into the scrotum. Another significant hormone in sexual differentiation is the anti-Müllerian hormone, which inhibits the development of the Müllerian ducts. For males during puberty, testosterone, along with gonadotropins released past the pituitary gland, stimulates spermatogenesis.
Health
Men accept lower life expectancy[xv] and higher suicide rates[xvi] compared to women.
Sexuality and gender
Male sexuality and allure vary from person to person, and a man's sexual behavior can be affected by many factors, including evolved predispositions, personality, upbringing, and civilization. While the majority of men are heterosexual, significant minorities are homosexual or bisexual.[17]
Trans men have a male person gender identity that does not align with their female sexual activity consignment at nascency and may undergo masculinizing hormone replacement therapy and/or sexual activity reassignment surgery, while intersex men may have sexual activity characteristics that do not fit typical notions of male person biological science.[xviii] A 2016 systemic review estimated that 0.256% of people self-identify equally female-to-male transgender.[19] A 2017 survey of lxxx,929 Minnesota students found that roughly twice as many female person-assigned adolescents self-identified as transgender, compared to adolescents with a male person sex consignment.[20]
Masculinity
Masculinity (also sometimes called manhood or manliness) is a set of attributes, behaviors, and roles associated with boys and men. Although masculinity is socially synthetic,[21] some research indicates that some behaviors considered masculine are biologically influenced.[22] To what extent masculinity is biologically or socially influenced is subject to contend.[22] It is distinct from the definition of the biological male sex, as both males and females can exhibit masculine traits.[23]
Standards of manliness or masculinity vary beyond unlike cultures and historical periods.[24] While the outward signs of masculinity look different in different cultures, in that location are some common aspects to its definition beyond cultures. In all cultures in the past, and even so among traditional and non-Western cultures, getting married is the almost common and definitive distinction between boyhood and manhood.[25] In the tardily 20th century, some qualities traditionally associated with marriage (such as the "triple Ps" of protecting, providing, and procreating) were all the same considered signs of having achieved manhood.[25] [26]
Anthropology has shown that masculinity itself has social condition, but like wealth, race and social grade. In Western civilization, for instance, greater masculinity usually brings greater social status. Many English words such equally virtue and virile (from the Indo-European root vir meaning man) reflect this.[27] [28]
Sex symbol
The Mars symbol (♂) is a mutual symbol that represents the male sex.[29] The symbol is identical to the planetary symbol of Mars.[thirty] It was beginning used to announce sex by Carl Linnaeus in 1751. The symbol is sometimes seen as a stylized representation of the shield and spear of the Roman god Mars. According to Stearn, nonetheless, this derivation is "fanciful" and all the historical evidence favours "the determination of the French classical scholar Claude de Saumaise (Salmasius, 1588–1683)" that it is derived from θρ, the wrinkle of a Greek name for the planet Mars, which is Thouros.[31]
