Dr. Robert Chapman, who was in charge of Diana's post-mortem, told an inquest into the deaths of Diana and her lover, Dodi Al Fayed, that the princess' womb and ovaries had showed no signs of pregnancy.
The princess perished alongside Al Fayed and their driver, Henri Paul, on August 31, 1997. Conspiracy theories have circulated ever since her death was announced. One of these is that Diana was pregnant with Al Fayed's child, and that the British establishment, not wishing to see her give birth to a "Muslim baby," had ordered the princess' murder.
Chapman told the inquest that he had carried out a routine inspection of Diana's womb and ovaries for signs of pregnancy. However, while he said he had found no signs of pregnancy, he added that if she had recently conceived there would not necessarily be anything for him to detect.
Dodi Al Fayed's father, Mohamed, has claimed that Diana's body was embalmed in Paris on the night of her death to mask the results of any pregnancy test.
The inquest is continuing.
