Menstrual Cycle

Luteal phase manipulation:

  • Not possible, PGF does not regress the CL

Follicular phase manipulation can involve:

  • Stimulation of follicle growth (Clomophene, HMG, FSH)
  • Induction of ovulation (HCG)

The average human menstrual cycle is 28 days in length with menses being 5 days, the follicular phase is 9 days and the luteal phase is 14 days.
