[Mass Effect] What does the existence of the asari and their method of sexual reproduction mean for the human definition of a "species"?

A species is often described as the largest group of organisms capable of interbreeding and producing fertile offspring. However, the asari have been successfully mating with several other species for hundreds of years. What does this imply?

iirc the Asari don't actually breed with another person. They reproduce asexually, with a caveat - their bodies require a second DNA template to create genetic recombination, the whole point of sexual reproduction. They basically "borrow" the DNA ideas of the other species to improve their own DNA.
