Most likely it is Morris Syndrome (Complete androgen insensitivity syndrome) rather than Swyer. People with Morris have a male karyotype (46, XY) and male gonads, but their external sex characteristics are typically female with vulva and vagina. They don't have a uterus, their testes are undescended, and they don't menstruate. Because of their testosterone, they are muscular.
I hadn’t heard of Morris Syndrome, but I do know that DSD’s come in a bewildering variety of forms. They are what they are. But the point remains: the governing bodies of athletics need to be honest about what is going on. The left wants things kept in a state of imprecision and confusion because it is trying to advance parts of its agenda under false flags.
