I haven't read anything about June having surgery.
She's been on complete hormone therapy for 15 months.
That includes testosterone blockers, and female hormones.
Her muscle mass has decreased.
Her strength has decreased.
Her ability to recover from hard workouts has decreased as a result.
Any advantage she may have now would be mostly from her growth period before she went on hormone therapy.
Teenagers and young adults who develop with testosterone levels of a male generally have larger frames, height, rib cage and lung capacity etc.
I realize that she has that large frame body, however now she has decreased strength because of her 15 months on hormone therapy.
Imagine taking a girl with her physical strength and then handing them the heavier boned body of a male.
There may be some perceived advantages but I think they are greatly diminished by the loss of strength and ability to recover.
One advantage I feel sure about is that June will not have a monthly period and loss of blood and iron levels that must be maintained.
However, it's not an easy thing to be on hormone therapy.
Caster Semenya said it made her feel terrible and decided not to do it.
I think after 15 months of hormone therapy that the playing field has been greatly leveled for June.
Rather than speculate, perhaps a study could be done with volunteer males who go on one year of hormone therapy.
