The good news is that the Washington Post, defying the inevitable cries that the paper is “transphobic”, is calling for a “respectful debate on trans women in sports”. This is, of course, because of the increasing number of biological men who identify as women (I prefer that jawbreaker to “trans women” because the latter plays into the misleading mantra that “trans women are women”), and because men who have gone through male puberty before transitioning have an inherent physical advantage over biological women. Even the UN now agrees on that, and gives data below on how many women have lost sports medals to transitioned biological men. I will, however, use “trans women” as shorthand in this article.
Just to see a major op-ed (by the editorial board!) defy the gender activists, who have censored all debate on this important ethical issue, makes me pleased. Read the article by clicking on the headline below or find it archived here.


You’ll note that the tone of the article is carefully monitored to ensure that a) the paper calls for “respectful” debate, when in fact what we need is just debate, and I haven’t seen any people discussing the issue being disrespectful to trans women; and b) although the op-ed doesn’t take sides, it cites accumulating data documenting the athletic advantage of trans women over biological women. There are enough data now, as we see below, to call for reform of sports regulations, so the debate is provisionally settled at present, though of course it’s about facts and those facts—and the resultant prescriptions—may change. For example, I don’t think there are any data showing that trans women outperform natal women in equestrian sports, though I can’t be sure: if men outperform women in horse sports, that means that even there different rules must be made. One thing is for sure: if there is a sport in which natal men do not outperform natal women, then by all mean let trans women compete with natal women. In such sports everybody can compete against everyone else.
But I digress: here are some excerpts from the op-ed. I have put other references below. Note the paper cited in the second paragraph; you may want to have a look. Also see the papers I cite below.
Trans people deserve to be treated with dignity, and the law should protect them from discrimination in areas such as employment and housing. But the realities of human biology raise legitimate questions about any notion that trans women should always and everywhere be treated exactly like cisgender women.
In athletic competition, male puberty confers significant advantages. While those biological differences vary by skill and sport, a 2023 paper by medical researchers in the United States and Italy noted that “it is well established that the best males always outperform the best females when the sport relies on muscle power, muscle endurance, or aerobic power.” The hormone therapy that many trans women take reduces some of those advantages over time, but research into how much those advantages can be mitigated, and over what time frame, is still ongoing. Other advantages, such as height, are fixed by the end of puberty. This poses obvious fairness and safety questions.
Note that the question is not just one of fairness—of transitioned biological men having unfair advantages competing against cis women—but of safety. A strong, muscular transitioned man could well injure a woman rugby player. This is why the English Rugby Football Union banned trans women from competing in women’s rugby. More from the WaPo article:
The public needs more and better research to make those decisions. But unless the data show that transitioning can fully erase the effects of male puberty, the country will also need a frank and open debate about the trade-offs between inclusion on the one hand and safety and fairness on the other.
And yet too often, efforts have been made to avoid or prevent discussion of those trade-offs by labeling debate inherently transphobic. This is not how a healthy democracy makes decisions.
Note too that gender activists ignore the palpable safety risk and of course the unfairness to biological women, saying that “trans women are women”, which means that trans women should have every right and privilege enjoyed by biological women. Well, I’d agree with that if by “right” one means “moral and legal right”, but I’ve always thought that there are some exceptions to the “rights” of trans women. Sport participation against biological women is one, of course. But trans women shouldn’t be allowed willy-nilly to be rape counselors advising unwilling women, monitors of shelters for battered or abused women, or inmates in jails holding biological women. Beyond that, I can’t think of many exceptions.
More from the article; notice that the public clearly recognizes the unfairness of having trans women in women’s sports:
A 2023 Gallup poll showed that almost 70 percent of Americans think sports participation should follow birth sex, not gender identity. Pressuring Democratic politicians to side with the minority, without giving sufficient space to the other side’s argument, is a recipe for irresolution and resentment.
The Democratic bit comes from the recent demonizing of Representative Seth Moulton (D, MA) for saying this: ““Democrats spend way too much time trying not to offend anyone rather than being brutally honest about the challenges many Americans face. … I have two little girls. I don’t want them getting run over on a playing field by a male or formerly male athlete, but as a Democrat, I’m supposed to be afraid to say that.”
For that Moulton was called a transphobe by Democrats, who should be more thoughtful, and Moulton’s campaign manager resigned. This is simple wokeness: performative virtue-signaling that defies the known facts. Of course the paper isn’t going to say that, but ends its piece this way:
We cannot predict whose argument will prevail. We can only say that no one — and certainly no political party — is entitled to win this debate by default.
Well, I would have put it more strongly, but I’ll take it.
A recent UN report (!) on violence against women and girls (pdf here) documents the possibility of violence and actually gives numbers for the medals lost by biological women to trans women.


Here are some data; the bolding is mine:
Policies implemented by international federations and national governing bodies, along with national legislation in some countries, allow males who identify as women to compete in female sports categories.28 In other cases, this practice is not explicitly prohibited and is thus tolerated in practice. The replacement of the female sports category with a mixed-sex category has resulted in an increasing number of female athletes losing opportunities, including medals, when competing against males. According to information received, by 30 March 2024, over 600 female athletes in more than 400 competitions have lost more than 890 medals in 29 different sports.
Note that one of the arguments for allowing trans women to compete against biological women is that there are so few of the former that it doesn’t matter. But even one medal taken away from a biological women is unfair, and I don’t see why there should be a threshold below which mixed competition is okay. Further, 890 medals in 29 sports is not a small figure!
Below the report notes that suppression of testosterone in trans women will not equalize the athletic potential of trans women and biological women. Testosterone levels used to be the criterion for Olympic participation of trans women or women with disorders of sex development, but the Olympics recently punted, saying that each sport must set its own criteria (again, my bolding):
Male athletes have specific attributes considered advantageous in certain sports, such as strength and testosterone levels that are higher than those of the average range for females, even before puberty, thereby resulting in the loss of fair opportunity. Some sports federations mandate testosterone suppression for athletes in order to qualify for female categories in elite sports. However, pharmaceutical testosterone suppression for genetically male athletes – irrespective of how they identify – will not eliminate the set of comparative performance advantages they have already acquired.This approach may not only harm the health of the athlete concerned, but it also fails to achieve its stated objective. Therefore, the testosterone levels deemed acceptable by any sporting body are, at best, not evidence-based, arbitraryand asymmetrically favour males.
Here are three recommendations from from the UN report (again, bolding is mine). These are conclusions, so are based on data. While more data are needed, what we have now is sufficient to actually make policy instead of simply calling for “more debate.” Of course more data will always be useful, but we have sufficient data to make provisional policy.
(b) Ensure that female categories in organized sport are exclusively accessible to persons whose biological sex is female. In cases where the sex of an athlete is unknown or uncertain, a dignified, swift, non-invasive and accurate sex screening method (such as a cheek swab) or, where necessary for exceptional reasons, genetic testing should be applied to confirm the athlete’s sex. In non-professional sports spaces, the original birth certificates for verification may be appropriate. In some exceptional circumstances, such tests may need to be followed up by more complex tests;
(c) Refrain from subjecting anyone to invasive sex screening or forcing a person to lower testosterone levels to compete in any category;
(d) Ensure the inclusive participation of all persons wishing to play sports, through the creation of open categories for those persons who do not wish
(d) Ensure the inclusive participation of all persons wishing to play sports, through the creation of open categories for those persons who do not wish to compete in the category of their biological sex, or convert the male category into an open category. . .
The last recommendation is one I agree with and have made before. I have written many times on this issue (see here and especially the papers I cite here).
Finally, here is a new editorial in the Scandinavian Journal of Medicine & Science in Sports. There are many authors, including developmental biologist and geneticist Emma Hilton, a colleague of Matthew’s at the University of Manchester. It’s a short piece (less than two pages); click to read.

Here’s a summary of their recommendations:
During press conferences at the 2024 Olympic Games, theInternational Olympic Committee (IOC) invited solutions to address eligibility for women’s sport. We take this opportunity to propose our solution, which includes: (a) recognizing that female sport that excludes all male advantage is necessary for female inclusion; (b) recognizing that exclusion from female sport should be based on the presence of any male development, rather than current testosterone levels, (c) not privileging legal“passport” sex or gender identity for inclusion into female sport; and (d) accepting that sport must have means of testing eligibility to fulfill the category purpose.
They recommend as an initial test a simple cheek swab that can determine the sex-chromosome constitution of women. If that shows deviations from the regular XX genotype, they then recommend “comprehensive follow-up in the rare cases that require extra consideration, with emphasis on the duty of care to every athlete. . . “.
I’m glad that the Washington Post brought this into the open, and with the approbation of its entire editorial board. Nobody involved in the discussions above is a “transphobe” who wants to deny men who identify as women legal or moral rights. But it’s time we admit openly that those rights are not unlimited—that the mantra “trans women are women” is not only biologically inaccurate, but also that the inaccuracy places a few limits on the rights of trans women.
