この研究の注釈：
Supplementation of 5 g of the root powder daily with skin milk for 3 months in infertile men with otherwise normal sperm morphology was able to increase sperm concentration and motility with more efficacy in men who were highly stressed (rather than heavy smokers or those who were neither) and was able to increase testosterone (10–22%) and reduce cortisol (11–32% AUC; 36-48% when measured at 4 p.m.) with similar favoring of stressed men.
