  • Cyclic Etidronate

  • Luteal phase

    The portion of the normal menstrual cycle from ovulation until the day before the next flow. A normal luteal phase is 10 days or longer (assessed by quantitative basal temperature methods) or 12 days or longer from the LH peak at midcycle. The length of the luteal phase is roughly proportional to the amount of progesterone in the cycle.
