Height is one contributing factor. It pales into insignificance compared to the advantage of being male.
There are more than two contributory factors as you will know.#
At the age of 17 a male is not typically fully developed muscularly, though some may be. Though do remember we are talking about data averages here.
At this age, the growth in bones is not yet accompanied by the muscle mass which will follow later. The advantage comes from lighter build, hence lighter weight, the narrowness of the hips and the high blood testosterone level.
Later upper body development will become a disadvantage in this discipline but an advantage in others.
Please don't pretend that I am saying that male biology is no advantage. That clearly isn't the case. But let's not pretend male biology is the only advantage, or that it is a dominating advantage in every competition.
Let's not pretend that the removal of all athletes who are either trans or have a DSD will have the effect of making sport an even playing field - it is the very existence of their not being an uneven playing field that produces winners and lowers. How genes are handed down doesn't make life fair.
