Martina Navratilova created a storm when she opined on transgender tennis players.

Her reasoning was that a man could change gender, play in womens' tennis and on retirement change back.

Now the mechanics of that concept is, admittedly, oversimplified but there is a worrying truth in there. And if athletes are prepared to use drugs to compete at the highest levels regardless of the long-term consequences why not surgery? Such surgical debate is rife in the arena of paralympics.

Money talks. And pays scant regard to fairness. And hormones are drugs, particularly when they are administered.

What is argued as fair for one is not necessarily fair for all.
