I have a copy and can answer your questions. There were originally 5 issues, released by 215 Ink, which were later collected.
There are no female transformations, and even the male ones are nothing to write home about.
The first 3 issues (out of 5) can be read
here.
It's not worth tracking the rest down.
Extinct is one of those annoying comic book homages to 80s movies that were never that good to begin with.
