Abstract
The effects of PMSG [pregnant mare''s serum gonadotropin] on the mitotic activity of granulosa cells and atresia of large follicles in 24 day old rats were examined. The labeling index decreased in atretic follicles parallel with a loss of FSH [folitropin] binding, and increased in hypophysectomized rats treated with FSH. FSH stmulates granulosa cell divisions and atresia may be caused by reduced binding of FSH to the granulosa cells.Keywords
