Ipsogender

Ipsogender or ipso gender describes an intersex person whose gender identity is the same as the gender they were medically assigned. An ipsogender person may or may not experience gender dysphoria and/or identify as trans.

It was coined by the intersex sociologist Dr. Cary Gabriel Costello in 2014:

"what I would suggest doing is adding to the terms "cis" and "trans" another term often used in scientific terminology. In chemistry, which gives us the language of cis and trans isomers, there are chemicals based upon a ring structure, called arene rings. When a chemical substitution is made in the same place on the ring, this is referred to as "ipso" substitution.

If we were to add the term "ipso gender" to trans and cis gender, we could perhaps describe intersex experience more accurately. A cis gender intersex person would be one with an intermediate gender identity, since that "matches" their birth sex. An ipso gender intersex person would identify with the binary sex they were medically assigned (the social sex substituted for their intersex birth status being the same as their identified sex). And a trans gender intersex person would be one who identifies with the binary sex other than the one they were assigned by doctors."
