FSH

 

  • Causes growth of follicles past antral stage.
  • Causes stimulation of granulosa cells in the ovary.
  • Stimulates establishment of LH receptors on granulosa cells.
  • Suppressed by Inhibin which is produced by the large follicles.
  • The pulse frequency probably initiates subsequent events in the cycle.
  • Half life of 60 minutes
  • Secreted at same time as LH, but other peaks during cycle may choose follicle for next cycle in polyestrous species.
