  • Publication number: 20140011781
    Abstract: Disclosed is a method for treating or preventing anemia. The method includes administering a testis extract serving as an active ingredient for treating or preventing anemia to a mammal. The testis extract is extracted by chloroform and methanol mixed solvent. The testis extract includes nandrolone, testosterone, androstenedione, estradiol, and estrone. The testis extract is prepared by using a method including: adding an extraction solvent to a testis to homogenize; filtering the homogenized mixing solution to remove residues; fractionating a filtrate without the residue to separate a supernatant and a under layer; removing water from the separated under layer; and concentrating an extract without water.
