A method of increasing the volume, the total sperm count and the reproductive performance of semen from human and animal males, is described. The method comprises administration of an effective dosage of a human or veterinary preparation containing at least one type of xanthophylls, such as astaxanthin, to said males. Preferably, the astaxanthin exists in a form esterified with fatty acids, e.g. in the form of algal meal produced by culturing of the alga Haematococcus sp. Further, the use of at least one type of xanthophylls, such as astaxanthin, for the preparation of a human or veterinary preparation for increasing the volume, the total sperm count and the reproductive performance of semen from human and animal males, is disclosed. |
