Man

Anyone with a male gender identity is male: he is a man or boy. Any man's manhood is valid regardless of what kind of body parts he has, or what gender he was assigned at birth. Having or wanting to have a penis are not what makes someone a man. People who were assigned male at birth (AMAB) or people who are perceived as men (PPM) don't necessarily identify themselves as men, which is the crucial criteria for whether someone is a man. Only identifying as a man makes someone a man. Cisgender men, transgender men, and intersex men are all equally men. Because gender isn't the same thing as sexual orientation, men are still men whether they feel sexual attraction to men (gay), or to women (heterosexual), either/any gender (bisexual or pansexual), or none (asexual).

In the Western colonialist gender binary system, "man" is considered to be one of the only two genders that exist, one of the binary genders. For all of written history, cultures all over the world have acknowledged people who were gender-variant or who transitioned to a different gender role than the one assigned to them at birth. Ancient cultures that thought of there being a specific number of genders did not always say there were just two. In ancient Egyptian writings, man was one of three genders, and in classical Jewish literature, man was one of six genders. The gender binary is an artificial and relatively new concept to humanity. Gender is not inherently binary. Therefore, "man" is not inherently a binary gender. Rather, "man" is one of many genders that people have. Throughout the history of the world, there have been many people who do not identify with being only female or male, who are therefore nonbinary. There are also people who identify partly as a man, and yet do not feel they completely fit into that category, so they call themselves nonbinary men. Although the gender binary system is coercive and limiting, "man" is a valid identity. Manhood can be better understood as an identity in its own right, rather than as an opposite pole in a binary system.

Etymology and terminology
The English term "man" is derived from a Proto-Indo-European root *man- (see Sanskrit/Avestan manu-, Slavic mǫž "man, male"). More directly, the word derives from Old English mann. The Old English form had a default meaning of "adult male" (which was the exclusive meaning of wer), though it could also signify a person of unspecified gender. The closely related Old English pronoun man was used just as it is in Modern German to designate "one" (e. g., in the saying man muss mit den Wölfen heulen).

Gender symbol


The symbol for male (as well as for the planet Mars in astrology, and iron in alchemy) comes from a set of symbols that were first used to denote the effective sex of plants (i.e. sex of individual in a given crossbreed, since most plants are hermaphroditic) by naturalist Carl Linnaeus in 1751. The male and female symbols are still used in scientific publications to indicate the sex of an individual, for example of a patient. Joseph Justus Scaliger speculated that the male symbol is associated with the Mars, god of war because it resembles a shield and spear; and that the female symbol is associated with Venus, goddess of beauty because it resembles a bronze mirror with a handle. Later scholars dismiss this as fanciful, The visual equivalent of a backronym, preferring "the conclusion of the French classical scholar Claude de Saumaise (Salmasius, 1588-1683) that these symbols [...] are derived from contractions in Greek script of the Greek names of the planets". Thouros (Mars) was abbreviated as θρ, and Phosphoros (Venus) by Φ, in handwriting.

Cisgender men
Cisgender men are men who were assigned male at birth (or were born with certain intersex conditions), and who have a male gender identity. Cisgender means "not transgender," as they don't transition to male from some other gender.

A few of the physical characteristics of a cisgender man often include: It is possible for a cisgender man to have a body with few of the above physical characteristics that are usually used to describe a typical cisgender male body. For example, cisgender men who have lost their genitals due to disease or injury are nonetheless real men, as much as they ever were. Furthermore, having the above characteristics do not make someone a cisgender man. For example, some people who were assigned male at birth but identify as a different gender have these characteristics. Some people with intersex conditions have these physical characteristics, but don't consider themselves cisgender men. Meanwhile, some intersex people consider themselves to be cisgender men.
 * No vagina or uterus. However, some men were born with one or another of them (persistent Müllerian duct syndrome). Some only find out they have a uterus if they have scans or surgery on their abdomen for other reasons, or if they menstruate.
 * Descended testes and scrotum, although sometimes testes never descend (cryptorchid), or are removed to treat or prevent disease
 * Penis or large clitoris. With some intersex conditions, the difference between these can be unclear.
 * Chromosomes that are XY (textbook example), XX (de la Chapelle syndrome), XXY (Klinefelter's syndrome), XXYY, or others.

Transgender men


Transgender men are men who were assigned female at birth (or had certain intersex conditions), and who have a male gender identity. Like any men, they usually ask to be called by "he" pronouns, and their sexual orientation can be gay, heterosexual, or otherwise. This is the female-to-male transgender spectrum. Older psychological and medical writings wrongly call trans men "female transsexuals" or "female transvestites", and call them by unwanted "she" pronouns. Trans men are men, not masculine women or butch lesbians.

Many transgender men transition to address gender dysphoria, and some also consider themselves to be transsexual men. Any transgender person's transition path is very individual. Common features in a transgender man's transition path include hormone therapy to create a balance with testosterone higher than estrogen, and surgery to remove breasts (double mastectomy, in this situation called female to male chest reconstruction), and sometimes to remove their internal reproductive organs (complete hysterectomy). Many trans men choose not to get genital surgery, or are satisfied with contemporary methods that create a penis that looks and works differently to that of a cisgender man. With hormones alone, a trans man can easily be seen as a man in daily life, which owes partially to how patriarchy polices manhood differently than womanhood.

Some cultures that recognize(d) female-to-male spectrum gender roles include the Blackfoot Confederacy (Ninauposkitzipxpe, "manly-hearted women"), the Navajo (Dilbaa), the Bugis people of Indonesia (calalai) the Maori (Wakatane), and Albania (Burrnesha, "sworn virgins"), and many others. Historically, these female-to-male spectrum people have included some people who were analogous to modern, Western ideas of trans men, as well as some possibly cisgender women who took up a male gender role or appearance in order to escape patriarchal oppression, to protect themselves from violence, and to have jobs that only men were allowed to have.

Nonbinary men
Some people identify as both nonbinary and as a binary gender such as male. They see themselves as almost but not quite fitting into the gender binary, and feel an association with being male, while still feeling that it's significant that they don't fit into that category. Depending on how the individual defines their identity, they may consider themself to be nonbinary men if they also consider themself to be a demiboy, butch, stone, lesbian man, genderfluid, genderqueer, multigender, eunuch, or other kinds of identities. A self-described nonbinary man may consider themself to be on the female-to-male spectrum, or trans masculine. However, a nonbinary man could also be someone who considers themself to be on the male-to-female spectrum, or trans feminine, and partly identifies with having been assigned male at birth.
