After Martina's intervention, and following Athletics TRYING to face up to the problem of Ladies who had Male characteristics, a fair amount if research has been done.
As I understand it, and I'm no expert, once the male body reached a certain point, after adolescence, they will retain a muscular advantage, even after all Surgical and Drug procedures have been completed.
This research continues.
The simple solution though is to have a Paralympic approach to the problem.
Different 'grades' for competitors, depanding what stage of trasnsition, their body is at.
Would anybody want to watch?
Well that isn't important as long as those who are interested in the Sport, rather than the Prize Money, have an opportunity to compete.
