“Jet London” is a Dutch ex-transgender activist. London spoke at the 2023 conference for anti-trans hate group Genspect.
Background
According to a deleted Twitter post:
“Born in 2000. After a traumatic 12-level spinal fusion surgery, and spending a year online, I concluded at 14 that I was trans. At 15 I was diagnosed with GD, at 16 I started hormone blockers (which made me suicidal), a month before 17 testosterone, at 18 I had a mastectomy.”
In another deleted 2023 Twitter post, London says the Tumblr and YouTube influenced the decision to transition:
“At age 14, I got sold lies on the Internet that made me doubt the material reality of my sex, and then people with medical degrees reiterated these lies, and experimented with chemicals and surgery on my body, while changing sex was never possible. The sheer stupidity of it all. […] Stupidity is at the base. They really believe the fantasy. After detransition I said I never turned into a man, and had been a woman on testosterone, and they asked if I think trans men are not men. Thank you! I’m on the mend and working on self-acceptance.”
London has used a number of aliases, including
- Jet or Jett
- Jet London
- eternalsamo
- “Iris”
Ex-trans activism
London now considers puberty blockers “a human rights violation.” London signed the Beyond WPATH petition critical of the WPATH Standards of Care.
In a 2025 paper in the anti-trans academic journal Journal of Sex & Marital Therapy, Lisa Anilo wrote:
One young Dutch detransitioner named Jet has publicly reported that puberty blockers she was prescribed at 15 followed by testosterone and mastectomy derailed her sexual identity development as a lesbian because the blockers first stopped her development and later the testosterone made her feel confused because she found herself having sexual attraction to men and it âwasnât a proper sexuality, it was only sexual and I wasnât like getting crushes on men, it wasnât a nice thing, it was very uncomfortableâ. After stopping testosterone at 21, she realized her gender nonconformity was not unusual for lesbians and went through the sexual development she wished she had gone through earlier, but found she couldnât access sexual feelings for women she was interested in having relationships with (Genspect, Citation2023). It is unclear from her experience whether longer term use of testosterone may have residual effects on desire or if this may be a result of early intervention with puberty blockers.
In a 2025 report by Genspect, they present Jet’s case study:
“I had never really had a crush on anyone before I went on puberty blockers. I never met any gay person before I went on puberty blockers, never met a lesbian. And thenâŠwhile I was on puberty blockers I met a lesbian girl and I knew I liked her but I justâŠI didn’t have any feelings for her, like I didn’t want to kiss her, I didn’t have any sexual feelings because I was on blockers. I knew I liked her, and it just wasn’t making any senseâŠI didn’t have my own sexuality and so I knew I was in love with this girl, but I wasn’t experiencing actual attraction to her. And like, you do need that sexual attraction when you’re crushing on someone. It’s important also in the context of love. […] I had no experience with my body, none whatsoever. Only at the age of 22 have I experienced healthy genitals, and non-painful orgasms and that sexuality is actually nice. While for those six years between age 16 and 22 I thought sexuality was gross, I thought my body was gross. My genitals hurt; orgasms hurt. I didn’t want to be with anyone. I was ashamed of my body and like I said I wasn’t actually crushing on anyone in a normal way. Nothing made any sense.”
