In the present study, concentrations of estradiol-17β and progesterone for P. paniculata-fed mice were significantly higher than those for control mice. Testosterone can be synthesized from progesterone and used to synthesize estradiol-17β. Therefore, the fact that the plasma concentrations of estradiol-17β and progesterone increased in female mice suggests an increase in the plasma concentration of testosterone in male mice. In humans, saponins can relieve impotency [4], and this could be attributable to increased plasma testosterone levels. This is an indirect effect of saponins on the testis and an indirect effect of adaptogens on testosterone [21]. In the present study, plasma concentrations of testosterone for P. paniculata-fed mice were significantly higher than those for control mice. Oral intake of P. paniculata therefore significantly increases levels of male and female sex hormones (estradiol-17β, progesterone and testosterone).

Some good info with references on the products site... I'm starting to like Barlowe's... reasonable prices, slow speed processing (no additives for processing), glass bottles, and real references for each product.
