Michael Jackson was in good health until he was injected with a lethal cocktail of drugs hours before he died.

The Los Angeles County Coroner's autopsy report has revealed the singer - who died of acute Propofol intoxication on June 25 - was not suffering from any serious physical problems at the time of his death.

Apart from slightly inflamed lungs and minor arthritis, he was in a "good condition", with a healthy heart and kidneys and "weight average for his height".

His sexual organs were also functioning normally, with the report noting Michael was still producing sperm when he died.

The findings are likely to put pressure on Michael's personal physician Dr. Conrad Murray - who allegedly injected him with the powerful anaesthetic that killed him - as it proves the singer had no underlying health conditions that might have contributed to his death.

The post mortem also revealed bizarre details about Michael's body, including a tattoo on his scalp that stretched from ear to ear in a bid to hide his receding hairline and baldness.

His remaining hair was "tightly curled" and cut short so it could be hidden under his long, flowing wigs.

His lips had been tattooed pink and his eyebrows blackened with more ink.

The coroner's report also suggests Michael was not lying about suffering from vitiligo - a rare skin pigmentation disease he blamed for his transformation from black to white - with the physician noting that he had patches of black skin on his legs and elsewhere on his body.

Injuries inflicted by frantic attempts to revive the star were also visible on his body, including cracked ribs and extensive bruising.

Michael's death was ruled a homicide last month.
