The injuries believed to have resulted from beatings given by his father Joe Jackson during his childhood days, reports Contactmusic.
Gossip blogger Perez Hilton said: "These injuries prompted Michael to visit a doctor while he was married to Lisa Marie Presley, in order to undergo a procedure that would increase his sperm count.
"We understand that the operation was not only extremely painful, but also may have been unsuccessful, leaving it impossible for Michael to father any children."
It has been claimed that the King of Pop- who has three children, Prince Michael I, 12, Paris, 11, and seven-year-old Prince Michael II, who is also known as 'Blanket' - reportedly confided in his physician Dr. Arnold Klein that he was left infertile from vicious beatings handed out by his father when he was younger and asked the medic to donate sperm to father his kids.
Michael passed away aged 50 in June after suffering a cardiac arrest due to "acute Propofol intoxication".
