Sexual inversion (sexology)

Sexual inversion (sexology) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sexual inversion (sexology) rather than just read about it. In short: Sexual inversion is a theory of homosexuality popular primarily in the late 19th and early 20th centuries. Sexual inversion was believed to be an inborn reversal of gender traits: male inverts were, to a greater or lesser degree, inclined to traditionally female pursuits and dress and vice versa; along with gay men, male sexual inversion also encompassed those assigned male at birth we today know as transfeminine, t…

Key takeaways

  • Sexual inversion (sexology) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sexual inversion (sexology) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sexual inversion (sexology) from memory before moving on to harder problems.

Reference excerpt

Sexual inversion is a theory of homosexuality popular primarily in the late 19th and early 20th centuries. Sexual inversion was believed to be an inborn reversal of gender traits: male inverts were, to a greater or lesser degree, inclined to traditionally female pursuits and dress and vice versa; along with gay men, male sexual inversion also encompassed those assigned male at birth we today know as transfeminine, though limited only to those attracted to men or both sexes, but never women on their own, since attraction to men for male inverts was a central part of the theory. The sexologist Richard von Krafft-Ebing described female sexual inversion as "the masculine soul, heaving in the female bosom". Initially confined to medical texts, the concept of sexual inversion was given wide currency by Radclyffe Hall's 1928 lesbian novel The Well of Loneliness, which was written in part to popularize the sexologists' views. Published with a foreword by the sexologist Havelock Ellis, it consistently used the term "invert" to refer to its protagonist, who bore a strong resemblance to one of Krafft-Ebing's case studies.

Historical context In 19th century Europe, where the theory of sexual inversion emerged, homosexuality was a criminal offense in most jurisdictions. The emergence of the theory of sexual inversion marked a turn in the conceptualization of same-sex sexual behavior from vice to congenital disposition.

Origin and popularization In 1869, the same year that Karl-Maria Kertbeny coined "homosexuality", Karl Friedrich Otto Westphal wrote a paper reporting on several cases of what he called "conträre Sexualempfindung", translated into English as contrary sexual feeling or contrary sexual instinct. This paper was published in the Archiv für Psychiatrie und Nervenkrankeiten in 1870, under the title "Die conträre Sexualempfindung, Symptom eines neuropathischen (psychopathischen) Zustandes". Arrigo Tamassia introduced the theory into Italian as inversion of the sexual instinct with the article "Sull’inversione dell’istinto sessuale" in 1878. Jean-Martin Charcot and Victor Magnan introduced the theory into French as inversion of the genital orientation with the article "Inversion du sens génital et autres perversions sexuelles" in 1882. John Addington Symonds used the phrase "sexual inversion" in "A Problem in Greek Ethics", which he wrote in 1873 and published privately in 1883.

Theory The theory of sexual inversion understands same-sex attraction as a form of gender variance. A sexual invert is someone who is attracted to their own sex, and the theory makes limited distinction between same-sex attracted people who are gender conforming apart from their attractions and same-sex attracted people who transgress assigned sex roles in other ways, such as crossdressing or cross-sex identification. According to this theory, gay men and lesbians were sexual "inverts", people who appeared physically male or female on the outside respectively, but felt internally that they were of the "opposite" anatomical sex (according to the binary view of gender). Therefore, same-sex desires and attraction were explained as "latent heterosexuality", and bisexual desire was known as psychosexual hermaphroditism – in other words, gay men and lesbians were really just heterosexuals who were "born in the wrong body", and "bisexuals" were what modern-day sexologists would call intersex people (formerly hermaphrodites) by this theory (the bisexual person's "male" part supposedly has attractions towards females, and the "female" part has attractions towards males).

Worked examples

Example 1 — a first encounter with Sexual inversion (sexology)

Start with the simplest possible case. Write down what Sexual inversion (sexology) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sexual inversion (sexology) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sexual inversion (sexology) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sexual inversion (sexology)

In research
Sexual inversion (sexology) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sexual inversion (sexology) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sexual inversion (sexology) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 19th-century neologisms, Gender identity, LGBTQ terminology, so understanding it makes those chapters shorter.
In everyday life
Look for Sexual inversion (sexology) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
