Malluci’s research into the perfect pair of breasts concludes that the Spice Girl's are the worst, while model Caprice has the best.
The scientist will discuss his work at a Breast Enlargement Conference in London next week.
The report claims that the ideal breast should be top heavy and have a nipple that points marginally upwards.
Malluci commented: "The ideal is a 45 to 55 per cent proportion - that is the nipple sits not at the half-way mark down the breast, but at least 45 per cent from the top."
