"Beginning in the mid 1920s, and yes the baby went to full term according to this scientist below... Ivanov started carrying out his experiments. First, he worked with human sperm and female chimpanzees, though he ultimately failed to create a sustainable pregnancy. Then he tried a more controversial method by introducing chimpanzee sperm to human females. Ultimately, the experiments were halted due to the death of his last chimp.
Due to the controversial nature of his experiments, Ivanov eventually came under scrutiny from the veterinary institute where he worked. It seemed that not everyone thought his experiments were as groundbreaking as he did, and in 1930 he was arrested and exiled. Two years later, Ivanov died from a stroke, but his strange idea would live on."
