It all starts off with a couple in the U.S. who were having trouble conceiving their second child. They decided to seek help and went to a fertility clinic, where eventually intrauterine insemination was performed. This involves washing and concentrating sperm before inserting it directly into the uterus of a woman around the time of ovulation to boost the chances of fertilization.
The assisted conception worked, and nine months later the happy couple welcomed a baby boy into the world. But then things started to take a turn for the weird. Testing revealed that the child’s blood type didn’t match up with his parents’.
