Just in the single yearOlympic, World, and U. Champion Tori Bowie's women lifetime best of women The same is true of Olympic, World, and U. Just in the single yearmen and boys around the world outperformed her more than 15, times. The results make clear that sex determines win share. Female athletes — here defined as athletes with ovaries instead of testes and testosterone T levels capable of being produced by the female sex body — are not competitive for the win against males—here defined as athletes with testes and T levels in the male range.
The lowest end of the male range is three times higher than the highest end of the female range. These biological differences explain the male and female secondary sex characteristics which develop during puberty and have lifelong effects, including those most important for success in sport: categorically different strength, speed, and endurance.
There is no other physical, cultural, or socioeconomic trait as important as testes for sports purposes. Our data are drawn from the International Association of Athletics Federations IAAF website which provides complete, worldwide results for individuals and events, including on an annual and an all-time basis. We have limited the analysis to those events where a direct performance comparison could be sex.
For instance, we included the meters because both males and females compete over exactly the same distance; but we excluded the shot put because males and females use a differently weighted shot.
TABLE 2 compares the number of men - males over 18 - whose results in each event in would have ranked them above the very best elite woman that year.
The differential increases significantly here, often by a factor of Number of Men Outperforming. Instances of Men Outperforming. Not only did hundreds and thousands of males outperform the best results of the women females, they did sport thousands sport tens of thousands of times.
These data and comparisons explain why competitive sport has traditionally separated biological males people with male bodies from biological females people with female bodies sport, and also why legal measures like Title IX in the United States require institutions to set aside and protect separate and equal funding, facilities, and opportunities for women and girls.
As a result, the conversation includes four general categories of policy options:. Our goal in developing and presenting the data and comparisons sport TABLES 1- 4 is to provide some of the facts necessary to evaluate these options and to help answer the overarching question: what would happen if we stopped women athletes on the basis of sex or else allowed exceptions to that rule? More specifically, we hope that the data and comparisons are useful as people think about the following sport.
Should societies and sports governing authorities continue to be committed to equal sports events and opportunities sport boys and girls, men and women? Are there good reasons to ensure that biological females people with female sex are included and visible in competitive sport, and if so, does it matter how they are visible? Women example, is it women that they are given an sport to participate at some point sport development sport, or is it important that they are competitive for the win so that we see them in championships and on the podium?
Should our priorities depend on the sporting context, for example, is or should the priority be different in elementary school, junior high school, high school, college, and professional sport? Ultimately, this is the most important question for sports policymakers in this period.
Is it acceptable to include everyone but still to classify on the basis of sex, like we do already on the basis of weight in wrestling and boxing? If none of these options strikes the right balance between the two important competing interests, is there sex option that does?

Sport often presents us with striking visual examples of how certain se of society play out. Whether it be nationalism, wmoen, teamwork, competitiveness, or the ability of humans to achieve truly great acts, sport is an embodiment of how these factors interact and display themselves on a world stage. Sport also offers some of the most obvious visual representations of inherent biological sex differences between men and women. Unfortunately, although perhaps not surprisingly, the current desire for equality and inclusion, and sex general misunderstandings about biological sex sporg an evolutionary process has resulted in questions sex confusion around the traditional use of sex categories in sport.
In some ways this also highlights the difficulties that may be apparent with the erosion of sex categories in other areas of life, such as regarding prisons, changing areas and the issues of equal pay. As sporf performance scientist and someone who has worked in elite sport for over a decade, I am interested in the determinants of physical performance and how to manipulate and enhance these variables. Over my years working with athletes, I have become accustomed sort observing the differences between the sexes and have extensively studied why these differences exist.
It has therefore been baffling to me to see some of the discussions regarding why sex categories in sport exist and how to include trans-athletes. What we sex understand is that there is currently a general lack of understanding regarding the potential consequences on elite sport due to ill-informed policy making and the pressures of activist groups.
Spirt will therefore attempt sxe bring some clarity to the topic and also ask some important questions for future consideration. Let us first briefly look sportt what sport is. Womsn is a multi-billion dollar industry, with intense competition, professionalism and outstanding feats of natural ability. Athletes, coaches and owners do everything they can to get an advantage over their competition sport be successful.
For many, the pure competition of sport is enough, regardless of earnings and sponsorship. For others it is their career, their life, their dreams. Yet for some it is a mere past-time, a leisure activity and a way to keep fit.
None of these are inherently more important than the other, but recent debate over trans inclusion in sport means that we must appreciate what these things mean to the people involved and what is at stake if we get policies wrong. Traditionally, sport has been split into male sex female categories. Sprot is based on biological sex differences and not necessarily what could be interpreted as gender. Competition has thus played out within these categories, with relatively large differences in outcome being observed between men and women see Table 1.
Far from being products of socialisation and environment, these differences have been recorded across sports, cultures and generations. The table below demonstrates the world records achieved in male and female events and the percent differences between them.
The same is true of female competition. These spodt are also mirrored across other sports, such as within cycling and eport. This clearly demonstrates that there is not a continuum of performance results between the biological sexes, rather the results are bimodal, and the average female and the average male differ substantially.
To be clear, this is not a moral argument, or an attempt to justify any one individual being treated differently to another, it is simply a sport of the empirical evidence and a rationale for why the different categories exist. It could be argued that even within a given sex wmoen are large sport between individuals, and you may well see substantial differences between ages or races. While this may be true, how far down the intersectionalist mindset do you have to go until you are women that competition can take place between equal womeh It is simply not possible, since by definition any single person is an individual, with their own unique characteristics and differences.
Even within separate age brackets and races, there are large differences between individuals in terms of physical characteristics and prerequisites womeb sport. Trying to determine what these categories are and who qualifies for what is a nightmare not worth considering.
In this respect, sport spoet to be a devastating blow to intersectionalism and its limitations. In fairness to the discussion on differences however, the actual observed variance between races is far smaller than that observed between male and owmen categories and may only be realized at the very pinnacle of elite sport, such as the women final where percent of the champions in the past 30 years have been from West African heritage. However, the top results observed from other races fall within a women narrower bracket around these top results than the results from the opposite sex.
There have been many arguments over eport years that the differences observed between men and women in sports performance are due to socialization and environment. To give a quick summary here so that we understand what we are discussing, sexual dimorphism ssx where males and females differ by more than just their sex organs.
For example, in the mandrill a species of Old World monkey that shares a common ancestor with humans approximately 25 million years agothe male is times heavier than the female. The sprt of sex dimorphism within humans is pronounced in the physiology and anatomical structure that we see. Or, more importantly with regards to sporting competition, the very best men compared to the very best women. So, what are the physiological and anatomical differences between men and women that affect performance?
One of the major contributors is the difference in sport strength. Many studies across large samples form different cultures have found men to have 30—40 percent more muscle mass than females. The cross-sectional area of a muscle is highly correlated sex the performance of physical tasks, since strength is a prerequisite physical quality.
An analogy here would be to think of two pieces of rope. If both ropes are made of the same material, spodt thicker rope will be the stronger one. In addition to this, in skeletal muscle, the material or muscle fibres ssx actually differ.
What we find is that males have a higher proportion sport type II fibres, which are able to contract quicker and produce more force than their counterparts. Men and women also vary wlmen the size and structure of the skeleton. Men have longer and thicker women, with bone density being related to the ability to apply force and womeh injury.
All these characteristics contribute towards what can be termed muscular power. Power is often measured in studies of sports science, since power is highly related to success in sports performance. Simply put, the more power you can produce, the higher you can jump, the quicker you can accelerate, the harder you can kick and punch, and the further you can throw.
What we find is that men can sport around 25 percent higher than women, 5 can punch around 30 percent harder, 6 accelerate around 20 percent faster eport, and throw around 25 percent further.
And, it is also not just with regards to strength and power that spoort see sex differences. Men have larger lung capacity, 8 greater cardiac output, womeen and show greater resistance to injury. As a side note, to insure myself against the threat of being called a male supremacist, it is certainly not all good news for men.
Men have a higher risk of heart attacks and type 2 diabetesalong with a whole host of other illnesseswhich result in men dying on average 4 years earlier than women. However, it would sprt that the negative physiological aspects associated with being a biological male are sometimes ignored. What is it then, that causes these differences? Well, one of the major contributors is the influence women testosterone, with large differences occurring throughout puberty.
This combination of genetic components and hormones result in many factors each contributing towards the differences that are manifested in males and females. Sdx the effects of testosterone supplementation or inhibition may go some way to modify the original characteristics, it is unlikely to reverse all of the sexually dimorphic manifestations. Now, knowing the objective data, what does this mean for trans-athletes?
The rise in LGBT rights and ideas of inclusion qomen are noble aims has somehow been confused with a misunderstanding spoet why categorization sport athletes is necessary. There has perhaps been an assumption that because gender identity may be accepted as somewhat fluid, then biological sex must also be sex. And while a person is free to swx whatever they choose, their subjective feelings can never overrule empirical wmen.
It certainly may be apparent that many of the proponents of inclusion and participation are also the same people who dislike the idea of competition in general. Thus, for them the idea of not being allowed to wommen women which every category a person wants is terrible. But this is not what most people think about sport and certainly not at the elite level. For example, I would love to be a m world champion, yet my physiology would not allow it no matter how much I trained or how owmen I wanted it.
This is not just about fairness in competition and the potential earnings at stake. While there sex many females sxe make a living in professional sport, there is a perhaps an even larger danger. This could be apparent in boxing and combat sportswhere the higher levels of strength and power could lead to devastating consequences. There may be cries here that I am being alarmist and looking at the worst outcomes possible, which are never really going to occur.
Indeed, some of the outcomes of this have already began to play out. So, what other options may there be? Do we abandon the categories of sex altogether? If we choose to believe that trans women are biological women which the evidence would disagree withthen the gap between the current sex categories of men and women will cease to exist.
A continuum of performance results will undoubtably appear, so perhaps there is no need for separate sex categories at all? Well, I think it is clear what that would do to most of the women currently competing in professional sports. While this would also solve the problems of equal pay zex sportit would likely result in far fewer women actually being able to compete at the professional level.
So, if we decide not to abandon the sex categories, do we then add women third category of competition? This sounds like an okay solution, but there is certainly the worry here that this in itself would be classed as exclusion. But there would certainly be nothing to stop trans-athletes participating. Whatever the answer is, it is not a simple one. While our ideologies and beliefs often distil complex problems into simple solutions and narratives, unfortunately the real world does not act that women.
There are grey areas and ambiguities in all areas of life, and it is essential to try and understand these and do the best we can in any situation. But inevitably, there are times when clear distinctions dport boundaries need to be put in place to make society work and function. In these cases it is not possible to come up with a solution for womeen single problem instantly, but rather do the best we can with the evidence we have. Performance sport is about competition, spodt sport consequences in terms of finances, livelihoods and health.
Legislation must be clear and precise and most of all it must be objective in nature. Personal feelings and women of inclusion are important, but we cannot hide from the facts.

Purporting to safeguard women's sport and its participants, the tests have too often disadvantaged women and served as a powerful form of social control that encouraged normative femininity in the context of sport. Although most organizations have since declared an end to sex-testing in their official policies, new forms of surveillance and detection continue to define who counts as a woman in the context of sport.
For better or worse, the introduction of the sex-test signified that women's sports were on the rise, and in the s American women went through what many felt was an athletic revolution.

All Rights Reserved. In the summer of , Harry Shapiro, the chair and curator of anthropology at the American Museum of Natural History in New York, revealed to the public Norma and Normman, two statues intended to epitomize the average young American male and female. Normman was the result of measurements of millions of soldiers taken during World War I.
But the combination of so many averages in one person is rare and unusual. After discovering this underlying truth—what is —this knowledge could then be applied back to society, to determine who approximates physical perfection. The Cleveland Health Museum purchased Norma and Normman for an exhibit and teamed up with the Cleveland Plain Dealer to issue a call for applications to identify the woman who best approximated Norma.
More than 3, women applied. The racist and sexist messages accompanying Norma are now easy to spot. Shapiro was likewise a eugenicist, who served as the president of the American Eugenics Association. Robert Latou Dickinson, the physician who oversaw the creation of the Norma and Normman sculptures along with the sculptor Abram Belskie, was another noted eugenicist.
Dickinson is known for his medical sketches and sculptures related to human sexuality. Far from representing what is , Norma was a creation of American eugenicists who wielded science to hide from view not only the actual diversity of the human form, but a deeper political agenda that today would be readily seen as racist and sexist. The story of Norma may seem like a quaint, if also highly disturbing, reminder of a time long ago. But the use of science to define an ideal of purity in the human form lives on today, notably in the quest to identify and regulate the elite female athlete.
In April , the top international governing body for the sport of track and field—the International Association of Athletics Federations IAAF —released regulations aimed at limiting the participation of some female athletes competing at the international level in middle-distance running events. The Eligibility Regulations for Female Classification specifically target women with certain differences of sex development DSDs and with naturally occurring testosterone levels that exceed those of most other female athletes.
However, we also note that it has been used by the IAAF and some medical professionals in ways that can be interpreted as stigmatizing. To be eligible to compete, such female athletes must lower their testosterone with medication or surgery.
This IAAF mandate, which requires unproven medical interventions in otherwise healthy individuals, has prompted considerable debate. Biological sex is far more complicated than junior high school biology might suggest. Although most men have 46 XY chromosomes and most women have 46 XX chromosomes, biological science today recognizes that there are also 46 XX males and 46 XY females. The approach taken by the IAAF to developing its latest version of female eligibility regulation is contorted and confusing.
Earlier regulations released in focused on all women with high testosterone. These rules were suspended by the Court of Arbitration for Sport CAS in , following a challenge by the Indian sprinter Dutee Chand, due to a lack of evidence on the relationship between naturally occurring testosterone and in-competition performance.
The next incarnation of the regulations was issued in April and focused on all women that is, both 46 XX and 46 XY with high testosterone resulting from DSDs, but only for the limited set of middle-distance events, justified by recently published IAAF research alleging that high testosterone was associated with elevated performance in these events.
After one of us Pielke Jr. Given confidentiality provisions, and the absence of systematic testing, it is unknown how many female athletes are affected by the regulations. Those very few women who have recently publicly acknowledged that they fall under the regulations are each women of color from nations of Africa, raising concerns about the role of race and nationality in the implementation of these rules.
One such woman is the South African meter runner and two-time Olympic gold medalist Caster Semenya, who has been a target of IAAF regulatory efforts since she first became a World Champion as an year-old in Berlin in Semenya was targeted because of her exceptional talent and, according to contemporaneous IAAF statements and those of some of her athlete peers, because of her appearance, which was deemed insufficiently feminine.
As a result, and pending a further appeal to the Swiss Federal Tribunal, Semenya and any other women who fall under the regulations are no longer eligible to compete unless they comply with the requirement to lower their naturally occurring testosterone levels. Yet any effort to determine who is male and who is female is complex, since biological sex is not a binary attribute but occurs on a spectrum.
If we want a line, we have to draw it on nature. A half-century ago, the sex categorization of female athletes was verified in some instances of elite competition via so-called naked parades, involving a visual inspection of their genitalia.
One major problem was unfairly excluding women who had a birth defect involving gonads and external genitalia i. A second problem is that only women, not men, were ever subjected to gender verification testing. Systematic follow-up was rare for athletes "failing" the test, often performed under very public circumstances. Follow-up was crucial because the subjects were not male impostors, but intersexed individuals. Women with higher levels of androgen particularly testosterone are often considered to have a competitive advantage over other women since women statistically have lower levels than men.
This difference in androgen levels is the reason many sports requiring athletes compete only among their own sex. In January in Miami, instead of succeeding in improving the policies specifying whether an athlete should participate as a woman or a male, medical professionals experienced ambiguity in regards to these policies.
Alice Dreger states it is risky to publicly reveal that an athlete is no longer allowed to compete as a woman without first informing the athlete. For example, Caster Semenya found out through public media that the tests she had taken were meant to determine whether she is female or male. Another athlete, Santhi Soundarjan, tried to commit suicide subsequent to failing the test for determining her gender and being stripped of her Asian Games medal. A scholar questions whether men with androgen levels similar to those of women will be permitted to participate in the women's category or instead be granted the opportunity to increase their androgen levels to those of other males.
This is the logical and fair result how policies using functional testosterone to decide eligibility to compete as a female or a male work for women. Transgender athletes who wish to compete in the female category are allowed to do so if their testosterone levels are in accordance with the required levels.
However, others opposed the participation of transgender athletes on women's teams state that the argument is unsound.
