The Brief

The International Olympic Committee issued a new policy last month, banning transgender women from participating in women's sports starting at the 2028 Summer Games and requiring all athletes who want to compete in the female category to undergo genetic testing.

The policy represents a significant inflection point in the ongoing political battle over trans women's participation in sports at all levels, including in California. It also marks a return to genetic tests that for decades dictated women's participation in the Olympics, and excluded transgender and many intersex athletes — those whose sex characteristics don't fall into the binary categories of male or female.

Genetic testing was required of women athletes for much of the second half of the 20th century, including the last time Los Angeles hosted the Olympic Games in 1984. Athletes had to present "certificates of femininity," according to the official report on the 1984 Games.

Those types of tests were stopped after the 1996 Games in Atlanta amid questions about their scientific efficacy and ability to assess what was an "unfair advantage," according to the IOC's own retelling.

Blanket genetic testing will return to the L.A. Olympics in 2028, bringing with it questions about how it will be implemented and who it will keep off the Olympic stage.

IOC says the science is settled. Some experts disagree

How to measure fairness in women's competition has been debated for at least a century, and different approaches have been used and abandoned over the decades. In recent years, the IOC had stopped requiring genetic tests and left rules around sex testing to individual athletic federations.

When IOC President Kirsty Coventry announced that the IOC would re-introduce a mandatory genetic test for all female Olympic athletes last month, she presented it as the final word on who can and can't participate in women's sports.

All women Olympic athletes will have to take a test to identify if they have an SRY gene, which is on the Y chromosome. According to the IOC news release, that SRY gene represents "highly accurate evidence that an athlete has experienced male sex development." Those with the gene will be excluded from competition except in some limited cases where the athlete is found to not to "benefit from the anabolic and/or performance-enhancing effects of testosterone."

"At the Olympic Games, even the smallest margins can be the difference between victory and defeat," Coventry said. "So, it is absolutely clear that it would not be fair for biological males to compete in the female category."

The new policy faced immediate pushback from human rights advocates and some experts in the field, including UC Irvine genetic expert Eric Vilain, who has previously advised the IOC on its inclusion policies.

He told LAist that the new IOC policy ignores women athletes with sex traits that aren't neatly aligned with the gender binary.

" Many of these athletes who were born intersex, they [looked] like a female baby, they were raised as female. They don't necessarily have male levels of testosterone," said Vilain, who said the science isn't settled on what advantage intersex women with a Y chromosome have in sport. " The answer to that is very unclear."

Decades of scrutinizing women athletes

Attempts to define the category of woman in athletic competition are nothing new.

Suspicion over the identity of women athletes started when they entered Olympic track and field competitions in 1928, according to Jaime Schultz, a kinesiology professor at Penn State who studies the history of women in sports.

" Track and field was seen as a masculine sport. The fear was that the sport would either masculinize women or else 'masculine women' might be drawn to the sport," Schultz said. "There was suspicion from the very beginning at the Olympic Games."

In the 1930s, two prominent retired athletes who had competed in women's sports transitioned to become men — exacerbating anxieties about any athletes who did not fit gendered norms.

"In the early 20th century, women’s sports were a source of moral and gender panic," historian Michael Waters, who wrote a book on those athletes, told Mother Jones. "Sports officials saw the idea that an athlete could transition gender as a threat to the binary categories they had built."

This led to the scrutiny of women who didn't fit gendered norms, according to Waters.

Women had to submit certificates from a physician in order to compete in track and field competition by the end of the 1930s, Jaime Schultz told LAist. Then came World War II and after that, the Cold War, when Schultz said suspicions turned to Soviet athletes who were suspected of "masquerading" as women. By the 60s, women in professional sport were subjected to gynecological exams and "naked parades" where they had to show their nude bodies to a panel to prove their sex.

" They ask the women athletes to strip naked and parade themselves in front of these three physicians, who sort of look them up and down and say, 'Yes, you're a woman, you can compete in women's events,'" Schultz said. "The visual inspections [were] humiliating to the women."

Those tactics were abandoned after outcry. That's when genetic testing entered the scene.

How genetic testing began for female Olympic athletes

At the 1968 Winter Games in Grenoble, the IOC began trialing a chromosome test called the "Barr body test," which counted X chromosomes to determine an athlete's sex. But that test was scientifically questioned.

"The stated aim was to detect male athletes posing as women, though in practice the test excluded women with naturally occurring chromosomal variations," according to a history posted to the IOC website in 2023.

One such athlete was Spanish hurdler Maria José Martínez-Patiño, who went to a competition in Japan in 1985, but forgot her certificate verifying her status as a woman. When she re-took the genetic test, she learned she had a Y chromosome and was barred from competition.

Martinez-Patino had androgen insensitivity syndrome, a condition that causes the person to have "genitals that appear female, but they don’t have female reproductive organs," as NPR reported. Officials determined she did not have an unfair advantage and she was eventually allowed to compete, but the process took years and was publicly humiliating.

"I knew that I was a woman, and that my genetic difference gave me no unfair physical advantage," Patino wrote in The Lancet in 2005. "I could hardly pretend to be a man; I have breasts and a vagina. I never cheated."

In 1992, the IOC introduced the SRY gene test that will now be re-introduced for the L.A. Olympics, according to Vilain at UC Irvine. That test was abandoned by the 2000 Olympics.

"There was so much outcry from the scientific community because it was also deemed not very ethical with lots of issues of privacy," Vilain said.

The rise of testosterone testing

What rose in place of the genetic testing was a new focus on testosterone levels in women athletes. That started in 2009 with South African runner Caster Semenya, who has differences of sexual development that meant she had higher than typical testosterone levels.

At the track and field World Championships, Semenya faced intense scrutiny from the public and sports officials over her appearance and gender identity. This fervor, recounted in NPR's series "Tested," led the governing body for track and field to require Semenya to take medication to lower her testosterone and implement limits to testosterone levels for female competitors.

That approach, too, has faced criticism from human rights organizations for its disproportionate impact on women from the Global South and the privacy issues it raises.

"A policy that calls for scrutiny of women’s naturally-occurring hormone levels — and, in practice, their bodies for signs of perceived “masculinity” ascribed to testosterone — is a form of policing women’s bodies, and passing judgment on their “femininity” as well as on their sex and gender identity," reads a 2020 report from Human Rights Watch.

The IOC's reintroduction of genetic testing has raised even more questions about the lines drawn around women's sports — and how those lines will be implemented come 2028.

In 1984, 1,610 women athletes underwent a "gender verification test" while in L.A., according to the official report on those Olympic Games. How testing will work this time around, who will pay for it, and what controversies it might unearth are still to be seen.

Southern California was built on radio.

"I can still hear the jingle KFWB News 98,” wrote  Taline in Los Feliz, during a recent conversation on LAist's daily news show, AirTalk, which airs on 89.3 FM. “I grew up hearing that in my dad's minivan on the way to and from school. It has a special place in my heart.”

Back in April, broadcast company Audacy announced KNX News — one of the last-remaining all-news FM stations — was leaving the FM dial where it had simulcast on 97.1 FM since 2021. The station, which is also one of the oldest in L.A., is not budging from 1070 AM where it has been on the air for more than 100 years. The move away from FM officially happened in May to make way for a new sports talk station, which Audacy officials called an area of growth for advertisers in today’s media landscape.

The move is one in a long line of changes for radio and a reminder that before podcasts, playlists and algorithms, many Southern Californians built their days around radio broadcasts.

Larry Mantle, now in his 41st year hosting AirTalk, remembers being a kid and dreaming of what it might be like to be behind the mic at one of these radio stations.

“ I grew up with KNX," he said. “My dream job as a kid was to be an anchor on KNX or KFWB, the two local all-news radio stations, 'cause there was nothing like hosting AirTalk that even existed at that point.”

Mantle opened up the phone lines on a recent show to hear from his fellow SoCal radio lovers about the shows they miss and the memories they have. Here's what they had to say:

“When you'd walk down Hollywood Boulevard where the station was, you could hear it playing as you went down the street,” said  Olivia in Glendale about KLAC 570 with Al Jarvis.

 Larry in Yorba Linda shouted out KBCA Jazz for its 24-hour jazz, saying “When I first moved out here in '68 from Phoenix, which had like an hour a week, it was a real wonder.”

 Mark in Glassell Park emailed that he loves KCRW’s Henry Rollins, writing, “I used to bristle at his unique DJ persona, but over time, I came to love him and his crazy eclectic playlists. I find his knowledge in history and punk rock fascinating. He's a gem and a legend."

"I'd like to give a shout-out to all the DJs working at KXLU, the college station at Loyola Marymount University, said  Jeremy in Culver City in an email. “That station's been on the air for nearly 60 years. I believe it's one of the best examples of what's possible with radio."

"KFWB and KRLA back in the day when they were rock music stations —  Dr. Demento, one of my favorite on-air personalities, also had eclectic music taste," said  Carrie in Desert Edge.

“ Dr. Demento was must listening when I was a kid in junior high school at Le Conte Junior High in Hollywood,” Mantle added. “Every Sunday night on KMET, we would make sure we were listening to Dr. Demento and his funny records.”

The question remains…

Listener support is vital to any radio station, and it’s clear KNX has many lifelong fans. AirTalk listeners highlighted their support for household KNX names over the decades like Bill Keene, Melinda Lee, Mike Roy and Jackie Olden.

As KNX makes changes, many are watching closely and thinking about the future of radio.

Listeners like Tommy in La Quinta are left wondering if the radio dial will be the same…

“I’m a hardcore listener, but I don't know about casual listeners [and] if they'll tune to AM,” he said.

After months of hand-wringing, Los Angeles and LA28 have come to a tentative agreement on how Olympics organizers will reimburse the city for its expenses for the 2028 Summer Games.

According to the deal, the private Olympic organizing committee will pay upfront for the estimated cost of services that are not eligible for federal reimbursement, like trash pick-up and traffic control. Under another proposal, the city would also be able to tap an LA28 contingency fund if it isn't fully repaid by the federal government for policing costs at Olympic venues.

The agreement is nearly nine months overdue and still needs approval by Mayor Karen Bass and the City Council.

The 2028 Olympics are intended to be privately financed, and an existing city agreement with LA28 states that the Olympics organizers, not L.A., will pay for extra costs for public services in support of the Games. But L.A. is the financial back-stop for the Olympics, meaning if LA28 goes in the red, taxpayers will pick up the bill.

Beyond that, the city services agreement presents another area where L.A. could incur additional unexpected expenses for hosting the Games. L.A. City Councilmember Monica Rodriguez warned LA28 CEO Reynold Hoover earlier this year that a bad deal could "bankrupt" the city.

Jacie Prieto Lopez, an LA28 spokesperson, and Paul Krekorian, who leads the city's office of major events, said in statements that the freshly inked agreement would help deliver a fiscally responsible Games.

"Mayor Bass’ priority is that the 2028 Olympic and Paralympic Games be fiscally responsible, protect taxpayers, and benefit Angelenos for decades to come. This agreement helps deliver that commitment," Krekorian said.

But the contract between the two parties doesn't fully resolve one of the biggest areas of financial risk for the city: the enormous cost of security for an event as extensive and high-profile as the summer Olympics and Paralympics.

Organizers are counting on the federal government to pay for public safety at Olympic venues that are considered part of a "national special security event." That includes costs for LAPD staffing. LA28 has not included security costs in its $7.1 billion budget — a fact that City Attorney Hydee Feldstein Soto criticized earlier this year.

The federal government has so far allocated $1 billion for security costs for the Olympics. Exactly where those federal funds will go has not yet been determined, and there's no guarantee they will cover all of L.A.'s policing costs.

To address this, city officials have also proposed an amendment to a 2021 agreement between the city and LA28. That amendment would establish that if L.A. is not reimbursed by the federal government for all its eligible expenses, it could dip into LA28's contingency fund of $270 million before the private organizing committee could use those funds for any legacy projects.

But that bucket of money will first be used for any costs that Olympics organizers still owe if they run out of revenue — meaning if the Olympics don't turn a profit, the city's access to that money will depend on how much is left for the taking.

Civil rights attorney Connie Rice, who has been tracking the city's negotiations with LA28, told LAist the agreement was a "PR document" not a deal. She pointed out that if the federal government does not pay up for security spending as expected, L.A. could be in trouble.

" It leaves the taxpayers with a GoFundMe strategy," she said.

The city services agreement lays the groundwork for more negotiations between LA28 and the city. Each venue will require its own agreement, to be negotiated by July 1, 2027. Venues in the city of L.A. include Dodger Stadium, the L.A. Convention Center, L.A. Memorial Coliseum and the Venice Beach Boardwalk.

The City Council's ad-hoc committee on the 2028 Games will meet Tuesday afternoon to vote on the agreement.
