| Research Abstract |
Thecorpusluteum regresses rapidlyif prolactin is not adequately supplied until the afternoon on diestrus 2.In this study, we focused onthemechanisms of time-specific determinationof thecorpus luteum life span in rats. Eventually, we clarified that1) local gonadotropin-releasing hormone could alter the expression ratio of prolactin receptor isoforms in corpus luteum, and 2) we could control theduration of luteal phase by changing that expression ratioartificially.
