BS. Sex is very clear cut. Determined by DNA. Male has testicules and produces sperm. Females have ovaries and produce eggs and carry offspring in their wombs. Clear cut as can be.
Mutations can occur making one intersex, but not female. The female category is a restricted category for a reason, to create a level playing field for females.
Agents should get together and not put up with placing their female athletes in races cheating non females.
