 [ Symptoms ] can a female human get pregnant from a horse  i do not think i am pregnant with a horse is baby but could this even happen [ Disease ] the pregnancy would not survive the sperm and egg of different species are incompatible technically a pregnancy may begin but will soon spontaneously terminate a human has 46 chromosomes with the male and female each contributing 23 chromosomes to their offspring a horse has 64 chromosomes with the male and female each contributing 32 chromosomes to their offspring a union between a horse and human would result in a shared chromosome total of 55 therefore the egg recognizes the irrational number of chromosomes and rejects the pregnancy
