    U.S. Study on Puberty Blockers Goes Unpublished Because of Politics, Doctor Says

    by

    The leader of the long-running study said that the drugs did not improve mental health in children with gender distress and that the finding might be weaponized by opponents of the care.An influential doctor and advocate of adolescent gender treatments said she had not published a long-awaited study of puberty-blocking drugs because of the charged American political environment.The doctor, Johanna Olson-Kennedy, began the study in 2015 as part of a broader, multimillion-dollar federal project on transgender youth. She and colleagues recruited 95 children from across the country and gave them puberty blockers, which stave off the permanent physical changes — like breasts or a deepening voice — that could exacerbate their gender distress, known as dysphoria.The researchers followed the children for two years to see if the treatments improved their mental health. An older Dutch study had found that puberty blockers improved well-being, results that inspired clinics around the world to regularly prescribe the medications as part of what is now called gender-affirming care.But the American trial did not find a similar trend, Dr. Olson-Kennedy said in a wide-ranging interview. Puberty blockers did not lead to mental health improvements, she said, most likely because the children were already doing well when the study began.“They’re in really good shape when they come in, and they’re in really good shape after two years,” said Dr. Olson-Kennedy, who runs the country’s largest youth gender clinic at the Children’s Hospital of Los Angeles.That conclusion seemed to contradict an earlier description of the group, in which Dr. Olson-Kennedy and her colleagues noted that one quarter of the adolescents were depressed or suicidal before treatment.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      How Does Pregnancy Change the Brain? Clues Are Emerging.

      by

      As hormones surge, some brain areas shrink in what scientists say may be a fine-tuning that helps mothers bond with and care for their babies.Research is revealing intriguing clues about how pregnancy changes the brain. Studies scanning women’s brains before and after pregnancy have found that certain brain networks, especially those involved in social and emotional processing, shrink during pregnancy, possibly undergoing a fine-tuning process in preparation for parenting. Such changes correspond with surges in pregnancy hormones, especially estrogen, and some last at least two years after childbirth, researchers have found.A new study, published Monday in the journal Nature Neuroscience, adds to the picture by documenting with M.R.I.s brain changes throughout one woman’s pregnancy. It confirms previous results and adds detail, including that white matter fibers showed greater ability to efficiently transmit signals between brain cells, a change that evaporated once the baby was born.“What’s very interesting about this current study is that it provides such a detailed mapping,” said Elseline Hoekzema, a neuroscientist who heads the Pregnancy and the Brain Lab at Amsterdam University Medical Center and has helped lead studies analyzing brain scans of more than 100 women before and after pregnancy.Dr. Hoekzema, who was not involved in the new study, said it showed that along with previously documented “longer-lasting changes in brain structure and function, more subtle, transient changes also occur.”Dr. Ronald Dahl, director of the Institute of Human Development at the University of California, Berkeley, who was not involved in the new study, said the emerging research reflected the key role of hormones in transitions like puberty and pregnancy, guiding neurological shifts in priorities and motivations.“There is that sense that it’s affecting so many of these systems,” he said. The study participant, Elizabeth Chrastil, is a neuroscientist at the University of California, Irvine. She became pregnant in 2019, at 38, after in vitro fertilization. That allowed precise tracking of her pregnancy from the start.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Can Stress Really Give You A Round ‘Cortisol Face’?

      by

      Online influencers claim the hormone can change the shape of your face. But experts say that misconstrues how cortisol works.“You’re not ugly. You just have cortisol face,” Mandana Zarghami told viewers at the start of a recent TikTok video, one of many on the social platform blaming a rounded, puffy face on high levels of the hormone.Hundreds of lifestyle and beauty influencers have claimed online that they’ve transformed their appearance by tackling stress. Many are sharing before and after photos that contrast their once fuller faces with new, lean jawlines, attributing the difference to lower levels of cortisol, the hormone produced in response to physical and mental stress. Some are even selling products and programs they claim will reduce cortisol and lead to a slimmed-down appearance.Ms. Zarghami, 28, said in an interview that her aim on TikTok was to educate people about the effects of high cortisol, though she does have a wellness business, through which she sells a “hormone-balance tea.”When she began experiencing visible swelling of her face and abdomen in 2020, Ms. Zarghami consulted a doctor, who suggested stress might be to blame. She felt frustrated by the response: “How can I control my stress if you’re not giving me tools?” she wondered.Ms. Zarghami made lifestyle changes that she believed had reduced both her cortisol level and her persistent facial swelling. These included drinking diluted apple cider vinegar after waking, and then green tea throughout the day. She also stopped weight lifting and instead started doing low-impact exercise and walking.Ms. Zarghami later shared those tips online, claiming that “cortisol face” could be tackled without drugs or expensive products. “I did a lot of research on how to fix this naturally,” she said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      The Question of Transgender Care

      by

      Hilary Cass is the kind of hero the world needs today. She has entered one of the most toxic debates in our culture: how the medical community should respond to the growing numbers of young people who seek gender transition through medical treatments, including puberty blockers and hormone therapies. This month, after more than three years of research, Cass, a pediatrician, produced a report, commissioned by the National Health Service in England, that is remarkable for its empathy for people on all sides of this issue, for its humility in the face of complex social trends we don’t understand and for its intellectual integrity as we try to figure out which treatments actually work to serve those patients who are in distress. With incredible courage, she shows that careful scholarship can cut through debates that have been marked by vituperation and intimidation and possibly reset them on more rational grounds.Cass, a past president of Britain’s Royal College of Pediatrics and Child Health, is clear about the mission of her report: “This review is not about defining what it means to be trans, nor is it about undermining the validity of trans identities, challenging the right of people to express themselves or rolling back on people’s rights to health care. It is about what the health care approach should be, and how best to help the growing number of children and young people who are looking for support from the N.H.S. in relation to their gender identity.”This issue begins with a mystery. For reasons that are not clear, the number of adolescents who have sought to medically change their sex has been skyrocketing in recent years, though the overall number remains very small. For reasons that are also not clear, adolescents who were assigned female at birth are driving this trend, whereas before the late 2000s, it was mostly adolescents who were assigned male at birth who sought these treatments.Doctors and researchers have proposed various theories to try to explain these trends. One is that greater social acceptance of trans people has enabled people to seek these therapies. Another is that teenagers are being influenced by the popularity of searching and experimenting around identity. A third is that the rise of teen mental health issues may be contributing to gender dysphoria. In her report, Cass is skeptical of broad generalizations in the absence of clear evidence; these are individual children and adolescents who take their own routes to who they are.Some activists and medical practitioners on the left have come to see the surge in requests for medical transitioning as a piece of the new civil rights issue of our time — offering recognition to people of all gender identities. Transition through medical interventions was embraced by providers in the United States and Europe after a pair of small Dutch studies showed that such treatment improved patients’ well-being. But a 2022 Reuters investigation found that some American clinics were quite aggressive with treatment: None of the 18 U.S. clinics that Reuters looked at performed long assessments on their patients, and some prescribed puberty blockers on the first visit.Unfortunately, some researchers who questioned the Dutch approach were viciously attacked. This year, Sallie Baxendale, a professor of clinical neuropsychology at the University College London, published a review of studies looking at the impact of puberty blockers on brain development and concluded that “critical questions” about the therapy remain unanswered. She was immediately attacked. She recently told The Guardian, “I’ve been accused of being an anti-trans activist, and that now comes up on Google and is never going to go away.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
