And of course he would have gone through male puberty, not female puberty. This would have been obvious then, and the result of this is obvious now if you see him in interviews. Male-typical build, male-typical vocal tone. Even his now-wife assumed (correctly) that he is male when she first met him.
Semenya has to double down on this narrative that he is a woman otherwise he will have to admit that his successful sporting career as a woman will have been a lie.
The key takeaway in my view is that the authors make a distinction between "category advantage", which is a systematic, structural, group-based difference that exists before competition even begins, and "competition advantage", which we see play out in competitive events and is based on a mix of factors including skill, preparation, and both innate and trained talent.
Where exactly to draw the line can be somewhat subjective (e.g. in weight classes) but it helps to explain why we have a separate female category: male physiology confers such a significant category advantage that, in open competition, it would limit the ability of female athletes to compete meaningfully and demonstrate their abilities. Having a separate category fulfils this desirable outcome of showcasing and celebrating female athletic excellence.
Often we see calls to add various classes of males, particularly ones who have chosen to identify as women, framed as "inclusion" but from the perspective of who this category is actually intended for it's the opposite. Drawing a clear eligibility boundary around the female category maximises inclusion of female athletes who would otherwise be disadvantaged and excluded.
Talent scouts specifically sought out males like Semenya who were erroneously registered as female at birth, knowing that their male physical advantage would give them an edge in women's competitions.
The specific condition he has (5-alpha reductase deficiency) is one that only affects males, conferring upon them internal testicles and a micropenis. But male development, including all the testosterone-driven advantages that distinguish male and female athletic performance, is otherwise normal.
His gold medal in the 2016 Rio Olympics women's 800m, along with silver and bronze being taken by two other males with similar conditions, is the reason why World Athletics (then the IAAF) and, later, the IOC started to move policy away from eligibility by identity documentation to empirical testing of sex advantage.
The policy change discussed in the linked article wouldn't have happened without athletes like Semenya taking advantage of the previous flawed policy, to the detriment of female athletes.
