Significantly shorter luteal phase length and longer follicular phase length were observed in the cycles with luteal dysfunction.
The time in between ovulation and when your next period starts is called the luteal phase.
The length of this time period is extremely important in getting pregnant; women whose luteal phase is between 12-16 days get pregnant much more easily than women whose luteal phase is only 10 or 11 days.
Instead of this being a discouraging discovery, use the knowledge to work with your doctor to balance your progesterone, which regulates the luteal phase, in order to increase your chances of getting pregnant.
Fertility Plus offers a downloadable chart for keeping track of your basal body temperature (taken each morning before getting out of bed), which rises during the luteal phase because of increased levels of progesterone.
