Trans men in the context of "Gender dysphoria"

A transgender (often shortened to trans) person has a gender identity different from that typically associated with the sex they were assigned at birth. The opposite of transgender is cisgender, which describes persons whose gender identity matches their assigned sex.

Many transgender people desire medical assistance to medically transition from one sex to another; those who do may identify as transsexual. Transgender does not have a universally accepted definition, including among researchers; it can function as an umbrella term. The definition given above includes binary trans men and trans women and may also include people who are non-binary or genderqueer. Other related groups include third-gender people, cross-dressers, and drag queens and drag kings; some definitions include these groups as well.

A trans woman or transgender woman is a woman who was assigned male at birth. Many trans women experience gender dysphoria resulting from the incongruence between their female gender identity and male sex assignment, which can be alleviated through gender transition.

The term trans woman is sometimes used interchangeably with the earlier medical term male-to-female transsexual, though the latter refers specifically to those seeking medical transition, and is generally considered outdated. Someone assigned female at birth with a male gender identity is called a trans man. The opposite of transgender is cisgender. Trans women may have any sexual and romantic orientation, including being straight (attracted to men), lesbian (attracted to women), or bisexual.

Gender-critical feminism, also known as trans-exclusionary radical feminism or TERFism, is an ideology or movement that opposes what it refers to as "gender ideology". Gender-critical feminists believe that sex is biological, immutable, and binary, and consider the concepts of gender identity and gender self-identification to be inherently oppressive constructs tied to gender roles. They reject transgender and non-binary identities, and view trans women as men and trans men as women.

Originating as a fringe movement within radical feminism mainly in the United States, trans-exclusionary radical feminism has achieved prominence in the United Kingdom and South Korea, where it has been at the centre of high-profile controversies. It has been linked to promotion of disinformation and to the anti-gender movement. Anti-gender rhetoric has seen increasing circulation in gender-critical feminist discourse since 2016, including use of the term "gender ideology". In several countries, gender-critical feminist groups have formed alliances with right-wing, far-right, and anti-feminist organisations.
