Prevention and amelioration of late-onset hypogonadism by food ingredients

PREV
Late-onset hypogonadism (LOH) is induced by age-related decline of testosterone synthesis, which leads to decrease muscle and sexual nature as well as mental symptoms such as depression. Now great attention is focused on prevention and amelioration of LOH via ingestion of foods and supplements.

We developed screening system of functional ingredients from food extracts for anti-LOH using testis-derived cells, and clarified that vitamins, nutraceuticals, and edible plant extracts have potentiating activities for the production of testosterone.
