Ohhh, I see my confusion now. My original comment was about Swyer syndrome, not CAIS. CAIS and Swyer Syndrome are very similar in concept but have a lot of important differences, especially in gonadal development. Usually in CAIS the testes will develop which can produce sex hormones, while Swyer syndrome leads to streak gonads which are generally functionless. Seems like there’s quite a debate about the timing of gonadectomy in CAIS indeed.
