Остров доктора Моро

Russian zoologist Ilia Ivanov was determined to find a way to hybridize humans and chimps, and successful hybridization of other animals convinced him it was possible.

After Ivanov was able to implant a human ovary in a female chimp, he unsuccessfully tried to inseminate her with human sperm, so he went in the opposite direction.

Ivanov imported chimps to Russia, inseminating unpaid Soviet women with their sperm, though none conceived because human and chimp chromosomes are incompatible.
