There's plenty of chromosome options that are not the classical male/female pairs.
So, you still haven't proven biological males are competing in women's sports.

Any variation from these typical numbers is referred to scientifically as an “aneuploidy.” If there is one additional X or Y, it is known as a “trisomy” (“tri” denoting the number 3). Genetic conditions that reflect a trisomy include:
Trisomies are the most common X and Y aneuploid conditions. Less common are “tetrasomies,” which denote the presence of four sex chromosomes:
Still rarer are the “pentasomies,” indicating five sex chromosomes:
Typically, 48- and 49-chromosome variations produce more pronounced symptoms than trisomies, although this is not always the case.
About X and Y Variations X and Y Variations, also known medically as Sex Chromosome Aneuploidy (SCA), involve variations in the typical number and type of sex chromosomes. The typical number of chromosomes in each human cell is 46. These include 22 pairs of “autosomes” (which refers to
