Historically, ewe reproductive capacity was negatively impacted by grazing on older cultivars of subterranean clover containing naturally-occurring phytoestrogens. Contemporary subterranean clover types still, however, contain phytoestrogens and it is unknown whether they pose a risk to ewe reproductive function. This thesis examined ewe cervix and uterus histology for markers of morphological and functional change in response to oestrogenic clover, compared to non-exposed controls. Results indicate that the proliferation of cervix glands correlate to aberrant reproductive outcomes in ewes exposed to phytoestrogens, indicating that current pasture phytoestrogen levels may impact ewe fertility.
