luteolysis.

  • The luteal phase is an earlier phase of estrous cycle.It begins with the formation of corpus luteum and ends in either pregnancy or luteolysis
  • Luteolysis is structural and functional degradation of corpus luteum.It takes place at the end of luteal phase of estrus cycle in the absence of pregnancy.
  • USE OF PROSTAGLANDIN
  • In domestic animals prostaglandin(Cloprostenol )is used for luteolysis.Luteolysis cause a decrease in progestirone level promoting an increase in follicle stimulating hormone(FSH) secretion which will start the development of new follicles on the ovary to start a new reproductive cycle.
  • Alternatively during a pregnancy,carpus luteum remains in the ovary releasing progestirone which will maintain a state of quiescence and close cervix until the delivery of fetus.
