Pop legend Michael Jackson led a controversial life and revelations about the star keep popping up even after his death. Recently, MJ’s former doctor Conrad Murray disclosed that his father Joe Jackson “chemically castrated” him as a boy.

Talking about Joe Jackson who died last month, Murray told The Blast: “Joe Jackson was one of the worst fathers to his children in history.”

He added that Joe had always been ‘cruel’ to his children. Michael had earlier opened up about the cruelty he had experienced at the hands of his father. “The fact that he was chemically castrated to maintain his high-pitched voice is beyond words,” Murray said.

Chemical castration has prevailed since 1944. It is a legal body chemical treatment used to reduce the level of testosterone in men, and also in women.

According to a report in The Daily Telegraph, Murray has previously claimed the Jackson family patriarch would give Michael hormone injections to stop his voice from getting deeper. The doctor said Michael told him he was so scared of his father that he would vomit when he saw him.

However, on the other hand, Jackson’s son Prince Jackson defended his grandfather in an Instagram video. “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. 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,” Prince said in the video.

“But he raised these kids right, otherwise they would have been in gangs or f****ing dead…” he added.

Joe Jackson died on June 27 in Las Vegas at age 89. He was buried in the same Southern California cemetery as his late son Michael Jackson.
