In The Critic, Louise Perry reviews Debra Soh’s recent book The End of Gender:
Contrary to what is commonly believed, sex is defined not by chromosomes or our genitals or hormonal profiles, but by gametes, which are mature reproductive cells. There are only two types of gametes: small ones called sperm that are produced by males, and large ones called eggs that are produced by females. There are no intermediate types of gametes between egg and sperm cells. Sex is therefore binary. It is not a spectrum.
The chapters in the first two thirds of the book are mostly concerned with the transgender movement. Soh works through trans activist claims with admirable thoroughness — no, not all people with gender dysphoria will benefit from transitioning; yes, natal males do have a physical advantage over natal females in sports; no, not all trans people are motivated to transition for the same reasons.
This last point is particularly explosive in political terms, but there is no doubt that Soh is on firm ground scientifically. Researchers have long been aware of the existence of two distinct categories of trans women — that is, natal males who identify as women. One group — sometimes called “homosexual transsexuals” — usually transition at a young age, have sexual relationships exclusively with men, and tend to be stereotypically feminine from childhood.
Another group — known as “autogynephiles” — have a very different profile: transitioning later, usually having sexual relationships exclusively with women, and often living as conventionally masculine men until they begin the transition process. And this second group are motivated to transition as a result of autogynephilia (sexual arousal at the idea of being a woman), a fact that trans activists are reluctant to acknowledge, preferring, as Soh puts it, “to neutralise the sexual aspect of their wishes to transition”. But she attempts an optimistic argument for tolerance:
In our sex-negative culture, trans women’s concerns are dismissed as a sexual fetish if anything about transitioning relates to sexual desire … I advocate for compassion and not being judgmental.
Soh, who writes for Playboy and other outlets, describes herself as sex-positive and supports destigmatising all discussion of sexual desire. Although I sometimes grew bored with the regular detours in which Soh writes about how much she loves going clubbing with her gay friends, or describes the confiding relationships she has formed with the parents of trans-identifying children, I understand the purpose of these sections: reassurance. This is a book written by a liberal for liberals, which prescribes a medicinal dose of yet more liberalism — more tolerance, more scientific inquiry, and more intellectual diversity. And liberal readers will no doubt be comforted that Soh’s live-and-let-live framing allows them to play the role of open-minded progressive, rather than (as trans activists would have it) bigoted reactionary.
