Pituitary–Ovarian Interrelationships in the Rat*

摘要: Publisher Summary The estrous cycle of the rat and its extension, pseudopregnancy—comparable to in most mammals—encompass two signal events: (1) release ovum at ovulation (2) function corpus luteum. These primal events are not only intimately involved producing a but, more importantly, also underlie reproductive process itself. They result from pituitary–ovarian interactions. In absence pituitary, ovaries become quiescent; ovaries, pituitary secretes gonadotropins rapid relatively constant rate. This chapter discusses some recent advances made understanding interrelationships arising, mostly, measurements hormones by radioimmunoassay. It explains secretion prolactin, regulation, role it plays controlling luteum during pseudopregnancy pregnancy.
