Women who keep to a low-fat diet when trying to conceive could be dramatically cutting their chances of pregnancy, according to a study. Drinking a pint of semi-skimmed or skimmed milk or eating two pots of yoghurt a day almost doubles the risk of an increasingly common condition in which women stop ovulating.

A new Harvard study says that women who ditch a low-fat diet for high-fat dairy foods have a better chance of ovulating better and getting pregnant.

Milk is an opaque white liquid produced by the mammary glands of female mammals (including monotremes). Mammary glands are highly specialized sweat glands. The female ability to produce milk is one of the defining characteristics of mammals. It provides the primary source of nutrition for newborns before they are able to digest other types of food. The early lactation milk is known as colostrum, and carries the mother's antibodies to the baby. It can reduce the risk of many diseases in the baby. Males of all mammal species retain the breasts that are part of the fundamental mammalian animal structure, hence their nipples. Lactation occurs in males in certain rare circumstances, both naturally and artificially, however, some pharmaceuticals precipitate lactation in males readily. The exact components of raw milk varies by species, but it contains significant amounts of saturated fat, protein and calcium as well as vitamin C.
