Sex runs the gamut, no matter what people think.
It doesn't. Sex is a biological process involving the fusion of two gametes (a sperm and an egg) to create a new being. The sexes are the two types of any creature which we recognise as male or female depending on which of the gametes they produce.
Males are the ones which produce the small gametes (sperm). Females are the ones who produce the large gamete (eggs). Both gametes contain DNA but the large one also has a food store - the yolk, for example, in a hen's egg. If sex was on a spectrum, there would have to be other gametes halfway between or different in some way to the others. There aren't any - it's only two gametes everywhere in nature.
Even if you believe there are only two genders,
Genders are not what we are talking about here - male and female refer to sex.
do you go by genitals or chromosomes? Because you know they can be different?
In humans the male gametes carry either an x or a y chromosome and a gene called the SRY gene, located on the Y chromosome. This is what decides the sex of the embryo. As soon as the sperm and egg fuse, the zygote (the fused cells) is either male or female depending on which chromosome the particular sperm carried.
The sexual development of a child in the womb follows one pathway if male and a different pathway if female. In very rare cases, things can go wrong and the sexual development can go awry - this is what a DSD is. However, all DSDs are sex-specific. Only male embryos get some conditions, only female embryos get others. Only a small proportion of DSDs result in ambiguous genitals or sex organs. For example, a very common male DSD is hypospadias - when the opening of the urethra comes short of the end of the penis.
A person with a DSD can develop non-functional sex organs of the opposite sex but what cannot happen is that the embryo actually develops into the opposite sex - in other words, it cannot develop the gametes which the opposite sex would produce.
Unless the male embryo has a condition called CAIS, the child goes through an almost normal male puberty.
It's important to understand that it is the sex of the embryo (fixed at conception) which determines the sexual development pathway. It's not the case that sexual organs or characteristics just develop randomly.
Can I point out that Khelif and Lin, the other boxer, were sex-tested by the IBA and accepted the chromosomal tests as accurate. XY is bog standard male. I posted the statement of the IBA upthread.
I feel awful for Khelif here. Not her fault they let her compete and so she did.
I don't feel awful for him, but the IOC are culpable for enabling him.
