The estradiol (E2) synthetic pathway converts testosterone to E2 via aromatase (AROM) and plays an important role in neuroplasticity. However, exogenous E2 increases cancer risk and interferes with gonadal function. Phytoestrogens, plant-based estrogens, may provide neuroprotection without negative E2 effects. Genistein (GEN), a soy phytoestrogen, preferentially binds to estrogen receptor beta (ER β), which is expressed at a relatively higher concentration than ER α in the cerebellum (CB). The songbird CB is an ideal model for steroid-mediated plasticity. Songbird brains are highly plastic and CB contains all steroid-synthetic enzymes. Previous studies in zebra finches (ZF) have shown that AROM and …

Soy infant formula which is fed to over half a million infants per year contains isoflavones such as genistein, which have been shown to be estrogenic at high concentrations. The developing testis is sensitive to estrogens, raising concern that the use of soy formulas may result in male reproductive toxicity. In the current study, male White‐Dutch Landrace piglets received either sow milk (Sow), or were provided milk formula (Milk), soy formula (Soy), milk formula supplemented with 17‐beta‐estradiol (2 mg/kg/d) (M + E2) or supplemented with genistein (84 mg/L of diet; (M + G) from postnatal day 2 until day 21. …
