From what I've read, these women all had CAIS or similar, and testosterone had no effect on their bodies. Thankfully the new IOC guidelines have an exception for that and would let them compete with women.

But I want to point out that XY+CAIS individuals cannot conceive or carry a child. They have no ovaries and no uterus.

They are, if they are female or have CAIS. Caster Semenya, for example, does not meet that standard. Caster was assigned female at birth and raised as a girl, but is not biologically female, rather a male with a DSD (5-ARD) who has testes and fully male levels of testosterone and musculature.
