According to Michael Jackson’s former doctor, Conrad Murray, his recently deceased father Joe Jackson chemically castrated him as a child.

In footage acquired by celebrity website The Blast, Conrad Murray, the pop icon’s doctor at the time of his death, called Joe “one of the worst fathers to his children in history.”

Murray was convicted of unintentional manslaughter and served two years in jail after giving the late King of Pop an overdose of propofol.

“The cruelty expressed by Michael that he experienced at the hand of his father…,” he began.

“The fact that he was chemically castrated to maintain his high-pitched voice is beyond words,” Murray, 65, said.

According to The Daily Telegraph, Murray previously alleged that the Jackson family patriarch would give Michael hormone injections to prevent his voice from becoming deeper.

In his 2016 book, This Is It! The Secret Lives of Dr. Conrad Murray and Michael Jackson, the former doctor made similar assertions.

“I hope Joe Jackson finds redemption in hell,” Murray stated in a video obtained by The Blast only days after Jackson’s father died of pancreatic illness on June 27.

“We want to thank you all for the support you have shown us as we grieve for the patriarch of our family. ​We mourn the loss of our father and celebrate the life of a man who sacrificed so much to give us the life and success we have today. ​Thank you for respecting our privacy during this time,” the Jackson family stated.

In the 2003 Martin Bashir documentary, Living with Michael Jackson, Micheal opened up about his difficult upbringing with Joe, and again in an emotional conversation with Rabbi Shmuley Boteach, which was published in the 2009 book, The Michael Jackson Tapes: A Tragic Icon Reveals His Soul in Intimate Conversation.

When Bashir asked Michael how frequently he was hit by Joe, Michael said, “Too much.”

The performer recalls, “It was more than just a belt – cords, whatever was around.”

He said Joe would “throw you up against the wall as hard as you could. He would lose his temper. … I was so fast, he couldn’t catch me half the time. But when he would catch me? It was bad. It was really bad.”

Despite the accusations leveled on Joe after his death, Michael’s son Prince defended him.

He informed his fans in an Instagram video that Joe has always done the right thing by his children.

“One of the things I”m going to talk about today is my grandpa about what you all got to f***ing say about him,” he said. “So you all can keep on talking all this s***, saying he abused my dad and all this and you will make a YouTube video about it for sure.”

“But he raised these kids right, otherwise they would have been in gangs or f****ing dead. So go ahead, keep talking s***, but you won”t ever be as great as one of that man”s f***ing balls in his n******.”

Murray was released from prison in October 2013 after serving two years of a four-year sentence following his 2011 conviction. His medical license has been revoked in three states.
