suggested that proliferation of bovine luteal parenchymal
cells was observed until day 8 of the estrous cycle. As
dramatic increasesin luteal fresh weights and DNA contents
were observed in the present study between days 2-12 of
the estrous cycle, we suggest that ovine luteal growth was
associatedprimarily with cellular hyperplasia, especially as
the protein/DNA ratio (an index of hypertrophy) was similar
on days 2-8 and actually decreasedbetween days 8-12
