Kevin J. Hsu (born circa 1990) is an American psychologist who published pathologizing research on sex and gender minorities while working with his dissertation advisor J. Michael Bailey at Northwestern University. He is a “gender critical” millennial associated with sexology’s conservative fringe.

Hsu diagnoses the common attraction to trans women as a made-up disease called “gynandromorphophilia” (GAMP), which he and his colleagues describe as “sexual interest in gynandromorphs (GAMs; colloquially, shemales).” Hsu and his conservative colleagues are the only people who publish medicalized and pornographic neologisms rather than using scientific and value-neutral terms used by ethical sexologists.

He also diagnoses furries as “autozoophiles,” ageplay enthusiasts as “autopedophiles,” and many trans women as “autogynephiles.” Hsu has published on sex and gender minorities with David I. Miller and Allen Rosenthal. He is one of the the few “autogynephilia” activists under age 50.


Hsu grew up in Texas and got a Bachelor’s degree from Northwestern in 2012 and a Ph.D. in 2019. He did his psychology internship in the Department of Psychiatry at the University of Illinois at Chicago.

His research has focused broadly on understanding sexual orientation using a variety of methods. His clinical work has focused primarily on the assessment and treatment of adults with various psychiatric problems, including anxiety, depression, and substance abuse.

Hsu’s dissertation was titled “Erotic Target Identity Inversions in Male Furries, Adult Baby/Diaper Lovers, and Eunuchs.”

Ethical controversies

FurFest ban and unauthorized intrusion

Hsu was barred from recruiting participants at Midwest FurFest in December 2013 by the organizers, but attended anyway and tried to talk to several furries about their sexuality.

Violative online survey

A complaint to Northwestern’s Institutional Review Board resulted in Hsu taking down an online survey he created. Matt Healy attempted to reason with Hsu before contacting Northwestern about a survey that the furry community and ethical furry researchers like Kathleen Gerbasi found concerning. Below is an excerpt from Healy’s complaint:

Kevin’s survey uses several trans slurs

Kevin’s survey uses very poor language. Furry has a large proportion of transgender people and genderqueer people – around one in four based on the data I have seen – people who are vulnerable and sensitive to poorly-chosen language.

Kevin’s survey most egregiously uses the offensive term “shemale”, and also uses terms like “transsexual” in ways that would be considered passe or problematic by people active in the area of queer politics. There are many of such people within furry.

When pressed, Kevin countered that “shemale” is acceptable because it is “used in professional literature.” He cited me two examples: one from [Ray Blanchard and Peter Collins in] 1993, the other from 2011. I reviewed the 2011 (Escoffier) paper, in which “shemale” is only used as a descriptor for a mainstream pornography category. Kevin’s use of this paper as a rationalization strikes me as either disingenuous or willfully misleading. His willingness to defend offensive terminology on specious grounds is consistent based on my conversations with him.

I advised him to use the GLAAD media guidelines as reference for appropriate use of language. Kevin replied: “The GLAAD guidelines are merely guidelines, and they are catered to the media, which we are not. They don’t dictate the discourse in academia, research, or really anything.”

Unethical “sissy” survey

Hsu often presents his cherry-picked data in an attempt to prove pet ideologies like “autogynephilia.” In 2021, Hsu began promoting a sex survey on non-representative gender diverse forums primarily associated with the sissy community and with “autogynephilia” activists:

Broadly speaking, we are hoping to better understand how gender, sexuality, mental health, personality, attitudes, and relationships intersect with one another in cross-dresser, transfeminine, and other communities (e.g., sissy), and how they might change over time. 

When questioned about the obvious bias in his sampling methodology, he said:

Thank you for raising these concerns. We agree that recruiting from only those subreddits that you mentioned would not capture the wide range of experiences within cross-dressing and transfeminine communities. We do plan to recruit not only from more cross-dresser communities online, but also transfeminine communities as well. We hope to recruit as much of a representative sample of cross-dresser and transfeminine people as possible; if we fall short of that for whatever reason, we can assure that we will be transparent about the limitations of the sample and generalizing of the results.

When questioned another time, he claimed:

We fully intend to post advertisements on and recruit from many other subreddits, forums, and communities to ensure a wide range of participants are included in the study. We have just not had the chance to do that yet

That has not happened as of 2022. The subreddits he contacted are:

  • askAGP
  • MEFetishism
  • TGandSissyRecovery
  • sissyology
  • sissyhypno
  • ForcedFeminization
  • Feminization
  • sissyplace
  • Sissy
  • Sissies
  • forcedfem
  • genderotica
  • gendertransformation
  • girlschool
  • SissyHeaven
  • SissificationProject
  • sissydressing
  • asiansissification

The project’s consent for research states at item 9: “Funds from the Conru Foundation will be used to support this research.”

Andrew Conru is the founder of AdultFriendFinder. His limited social media presence includes primarily interacting with people associated with the intellectual dark web and with signers of the Harper’s letter, including Dave Rubin, Eric Weinstein, James Lindsay, Tim Pool, and Katie Herzog (quoting Benjamin Boyce).
