Women's pro boxing and MMA don't have DSD rules but would presumably introduce them if an athlete blatantly switched from the amateur game after falling foul of such policies.
And at 26 years old it's presumably going to be far too late for IK to learn another sport to a really high level.
Track and field is out because of its DSD rules.
Tennis has no DSD regulations... but it's such a skill based game, no-one could ever get to pro level after picking up a racket for the first time in adulthood.
In basketball, the WNBA seems to allow DSD athletes [e.g. Britney Griner] but IK's height is nothing special by WNBA standards, and it's a very popular, very competitive sport.
Football has no DSD rules and is by all accounts something that IK has played before, but it's a globally popular game, could IK really do well there? And who'd bet against a DSD ruling being brought in within the next few years, no doubt sooner if they had a high profile defection from a sport with a DSD policy [whereas one or two did manage to discreetly switch in from athletics when they introduced restrictions]?
