I'm not one for speculation, but it hasn't outright been stated, or at least I haven't heard, that every unit was female. But Mori could be just throwing us a reel to cause a fan uprising. Embryo Storage units only appear in the XBlaze spinoff visual novel (which Ragna doesn't appear in at all and takes place way before Blazblue does (around the 2050s to be exact)). It's more likely that Ragna is a Murakumo Unit than an Embryo Storage unit.

Also, only Murakumo Units 11-13 were based off Saya. Units 2-10 were made by other companies and therefore were likely to have been based off other people. If Ragna was revealed to be among them, then he would more likely be based off Jin Kisaragi's and Saya's father rather than being their older brother.
