Today I learned something new. Human hamster hybrids are a real thing and are not all that rare. A humster, as the name implies, is a hybrid using human sperm and a hamster ovum. Don't worry, they are not viable (we hope) and are killed off very early. One of the uses of them is to test the viability of human sperm when planning to use them in in vitro fertilization.
