Objectives:

Our overall objective is to determine the effects of soy-related phytoestrogens on mammalian reproductive system differentiation and function.

Specific Aims:

    1. To determine the effects of phytoestrogens on steroidogenesis (ovarian health) and apoptosis (ovulation propensity) in cultured primary granulosa cells from porcine ovaries .

    2. To determine the effects of phytoestrogens on the reproduction of rats and pigs fed these soy products.

    3. To determine the kinetics of specific phytoestrogen binding to an estrogen receptor and the effects soy-related phytoestrogens have on cell proliferation and apoptosis (programmed cell death) in cultured primary cells derived from fetal porcine reproductive progenitor organs.
