Female animals, deprived of a sufficiency of these essential factors, show a characteristic type of secondary sterility. Pregnancy, which begins in a perfectly normal manner, is suddenly terminated by the death and resorption of the foetus. In the male a deficiency of E may cause premature degeneration of the spermatogenic tissues. The vitamins are found in green plant tissues, but the richest source is the oil extracted from wheat embryo. This oil, and con- centrates prepared from it, have been used successfully in the treatment of certain forms of sterility in farm animals which have lately been suspected of E-deficiency conditions. In Denmark, Canada, and more recently in this country, similar treatment has also been applied, again with a good deal of success to certain forms of habitual abortion in women. In a series of twenty-eight women who had experienced two or more abortions, twenty-one treated with wheat germ oil produced healthy children. [ 13 ]
