The present invention relates to a method of improving a reproductive potential of a male mammal using an ultra-weak photon. The ultra-weak photon according to the present invention is in a visible light spectrum but is transmitted as weak light that is not visually recognized so that the ultra-weak photon does not provoke stress and can be irradiated safely for a long time, thereby improving the reproductive potential of male mammals. Unlike an existing material feeding method of improving a reproductive potential, in which a material is supplied wastefully and environmental pollution problems are caused due to tolerance and misuse, the present invention relates to a useful alternative technology that can be used for a long time and ensure the sustainability of livestock industries.
