The Download: Fertility for trans men, and a Q&A with CRISPR’s co-creator

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

Trans men's eggs have been matured in the lab-and could help them have children

Ovaries contain hundreds of thousands of underdeveloped eggs, held in a kind of suspended animation. Each month, one matures and is released-potentially to be fertilized by sperm and create an embryo. For the first time, scientists say they have managed to take eggs from the ovaries of transgender men and get them ready for fertilization in a process completed entirely outside the body.

The achievement, carried out by a team led by Evelyn Telfer, a reproductive biologist at the University of Edinburgh, suggests that viable eggs can be obtained from transgender men even after years of testosterone therapy, which can stop ovulation.

While freezing eggs is an option for transgender men who want children, this typically involves stopping testosterone treatment and allowing a menstrual cycle to return. This can take months and cause fatigue, mood changes, and sleep problems. The need for vaginal probes can prove particularly distressing for transgender men.

Telfer and her colleagues' alternative involves taking eggs from the ovaries and maturing them outside the body, in the lab. This new technique could not only help transgender men but also many others struggling to concieve. Read the full story.

The scientist who co-created CRISPR isn't ruling out engineered babies someday

Jennifer Doudna is the co-discoverer of CRISPR editing, the revolutionary method for engineering genes that, 10 years after her original breakthrough, is now making its way into human trials.

There's an expanding list of applications in diagnostics and engineered plants; already researchers are exploring potential treatments to cure sickle cell disease, blindness, and liver disease. In 2020, she shared a Nobel Prize with fellow scientist Emmanuelle Charpentier. The two became the sixth and seventh women to win the award in chemistry.

Perhaps more than anyone, she has been able to relay to the public the formidable power of versatile gene editing as well as the possible downsides of the technology. Antonio Regalado, our senior editor for biomedicine, spoke to her about this and other issues, including the surprising reality of a legal system where the key CRISPR patent could go to someone other than the person who won a Nobel for the discovery.

The US now hosts more child sexual abuse material online than any other country

The US hosts more child sexual abuse content online than any other country in the world, new research has found. The US accounted for 30% of the global total of child sexual abuse material (CSAM) URLs at the end of March 2022, according to the Internet Watch Foundation, a UK-based organization that works to spot and take down abusive content.

The US hosted 21% of global CSAM URLs at the end of 2021, according to data from the foundation's annual report. But that percentage shot up by 9% during the first three months of 2022, the foundation told MIT Technology Review.

The short-term spike can at least partly be attributed to the fact that a number of prolific CSAM sites have switched servers from the Netherlands to the US. However the rise of CSAM in the US is down to a number of more long-term factors, including the lack of legal incentive for tech companies to invest time, money and resources into keeping abuse content off their platforms.
