Document Summary
Common themes across non primates: uterus is the transducer b/w ot pulses & pgf2a pulses, countercurrent transfer of pgf2a from uterus to ovary all species that have cl maintenance after hysterectomy have a bicornuate uterus, if you take out the uterus (both horns), will have an extended luteal phase, take out the source of the signal that would knock it back, humans if you take out the uterus (leave ovary), go through cyclical ovulations like normal. Prevention of polyspermy: o cortex of zygote with egg membrane cortical reaction other sperm can enter o impair more sperm binding reaction. Bpa can influence early meiotic events & the oocyte itself o synaptic defects & increased levels of recombination o eggs & embryos o disruption of estrogen receptors o the estrogen receptor o may be directly responsive to estrogen during early oogenesis o mimic or antagonize the effects of estrogen will influence oocyte development in the female fetus.
