With the injection of external [erythropoietin, a protein that increases oxygenation], elite athletes — often cyclists — have been enhancing performance for years, but authorities have caught on. Anti-doping controls can now detect external EPO efficiently through blood and urine tests.

Another way to dope an athlete’s genes is through CRISPR, or CRISPR-Cas9, a technique that allows geneticists to edit specific parts of a person’s genome by removing or altering sections of DNA — also known as gene editing.
The technique is rapidly developing, leading to a World Anti-Doping Agency announcement in October that it was expanding its “gene-doping” ban to “gene editing agents designed to alter genome sequences and/or the transcriptional or epigenetic regulation of gene expression.”

Asked what it is doing to monitor and test athletes for gene doping, the International Olympic Committee did not comment directly but said, “We have nothing to add to the section on gene doping in [World Anti-Doping Agency’s] prohibited list.”
