ENCORE: Sex medicine doctors are putting women’s health, and pleasure, first

After a seemingly innocuous question about pi, Allan Brooks tumbled down a ChatGPT rabbit hole. Three weeks later, he emerged, after spending 300 hours in a spiralling 7,000-prompt exchange with the chatbot. Dr. Keith Sakata, the psychiatrist whose viral thread on X breaks down the phenomenon known as “AI psychosis,” says the built-in sycophancy of large language models like ChatGPT needs to change before more harm is done.

How much would you be willing (and able) to pay to get your knee or hip replaced? Calgarian Linda Slater's knee pain became unbearable during her two-year wait to see an orthopedic surgeon. She drained her retirement savings to pay $30,000 for a new knee at a private Toronto clinic. Dr. Rick Zarnett, an orthopedic surgeon who works out of both a private clinic and public hospital, says the system needs to improve so patients can get surgery sooner.

Companies are spending big bucks advertising weight-loss drugs like Rybelsus, seeing huge potential in capitalizing on the popularity of Ozempic. But in Canada, so-called "reminder ads" can give only the name of the medication, not what it's for, telling people to ask their doctor for details. Ad man Terry O’Reilly says it can result in bad ads that turn people off, and pharmaceutical policy expert Barbara Mintzes says reminder ads can lead to overtreatment and high costs, doing more harm than good.

As a rapper, Bishop Brigante was no stranger to on-stage battles. We met up with the then-45-year-old when he was battling Stage 4 colon cancer, which he said was caught too late. Bishop wanted Canadians to have easier access to colonoscopies and said advocacy had given him newfound purpose.

 Many women report difficulties with orgasms, low libido or pain around intercourse. And given that many have never even learned much about their genitals, they don’t always know where to get help. A cadre of Canadian doctors specializing in women’s sexual health is trying to change that. They’re helping patients boost pleasure, while empowering them to get to know their sexual anatomy.

Attracting a family doctor to work in a community is challenging, with fewer physicians choosing family medicine. That's why Cheryl Gnyp, the recruiter for Castlegar, B.C., needs to stand out. She uses the board game Operation and specialized coffee as part of her 10-minute sales pitch to potential recruits at conferences. It can take years before a doctor starts working in the community, but she’s in it for the long haul.

Judith Morrison needs a kidney. While she's on dialysis, her sister Catherine is putting out a public plea for a living donor. But the search has been hard. And if they do find a donor, the sisters say that person will have to go through a long and opaque testing process. A process that experts say needs to be improved across Canada because the demand for kidney donations is high.

One morning as she arrived for her hospital shift, Winnipeg nurse Jennifer Noone was assaulted outside the staff entrance, leaving her with a bad concussion and PTSD. Rather than stay silent, she took the unusual step of having her assailant charged with assault. Manitoba Nurses Union President Darlene Jackson says there needs to be more and better security and violence should not be accepted as just part of the job.

At 28 years old, Dr. Soania Mathur was building her medical practice and expecting her first child. Then, she was diagnosed with Young-Onset Parkinson’s Disease. She tried to ignore her diagnosis for a decade, but as the symptoms progressed, she had to close her practice. Now, the self-described "Unshakeable MD" uses her experience as both a patient and a doctor to advocate for especially young people living with Parkinson's, as up to 10% of patients are under 40.

How far would you go to test your body in extreme heat? Ironworker apprentice Britnee Miazek travels hundreds of kilometres to Brock University in St. Catharines, Ontario for a gruelling experiment to see how her body deals with high temperatures. She wants to find out why she stopped getting her period while working in sweltering conditions on a coke oven. Researchers are hoping to find answers for Britnee, and understand more about the long-term health effects of working in an increasingly hot environment.This episode is part of a CBC collaboration called "Overheated" where White Coat, Black Art, What on Earth, and Quirks and Quarks explore how heat is affecting our health, our cities and our ecosystems.
