«These results suggest that phytoestrogens can interfere
with the normal
estrogen feedback mechanisms
with respect to release
of gonadotropin in the ewe... although most studies into the effects
of phytoestrogens have concentrated on changes in the reproductive tract, there are indications that they interfere
with the
hormone balance between the ovaries and the hypothalamo - adenohypophysical system... ewes on phytoestrogens have shown follicular abnormalities such as numerous small follicles, deficient antrum formation and signs
of early atresia... it is possible that the permanent changes brought about by phytoestrogens in the brain are a result
of these compounds interacting
with estrogen receptors in this tissue, and subsequently influencing the re-synthesis or replenishment
of cyto - plasmic
estrogen receptors... phytoestrogens can interfere
with the delicate feedback mechanisms involved in the release
of the gonadotrophins.»
