tests begin in women's athletics - new rule explained www.bbc.com/sport/athletics/articles/c9d07jq6vpeo This article lays out the history and reasoning behind the reintroduction of genetic testing for athletes. I thought it was v good, clear and factual. Adds info such as “At the 2016 Olympics in Rio, all three medallists in the women's 800m (including winner Semenya) were DSD athletes, intensifying calls for tighter rules.” which is a clear way of explaining to those without much prior knowledge why this matters and isn’t an insignificant thing.
