Guided by the mucus observed at the vulva by the woman, bleeding and basal temperature, trained caregivers to restorative reproductive medicine)
identify potential anomalies revealed by these observations (duration and aspects of discharges, aspect of the thermal curve)
use targeted hormonal tests (ie prescribed at the right time of the cycle)
prescribe the complementary tests needed to identify any factors that might be inhibiting natural fertility.

The approach to investigation begins with the type of menstrual cycle with which the patients presents:
Regular menstrual cycles,
Long and irregular cycles,
or the absence of menstruation.
At the first visit that information can be easily obtained and an infertility evaluation can begin.

In case of Regular menstrual cycles
After two cycles of charting, the patient return.
The physician review the cycles with the idea of paying special attention to the following biomarkers:
the type of mucus cycle (see the definition in the item Miscellaneous)
the length and stability of the post-Peak phase
the length of the pre-Peak phase and its characteristics
the length of the cycle
presence of premenstrual spotting
presence of tail-end brown bleeding.
From T Hilgers, The NaProTechnology Revolution, page 237
A short post-Peak phase will indicate the presence of an inadequate short luteal phase.
A long post-Peak phase may suggest the presence of a persistent unrupted follicle.
Premenstrual spotting and/or tail-end brown bleeding may indicate the possibility of low progesterone levels. These also can be associated with chronic endometritis (an infection of the lining of the uterus).
At the second visit... see T Hilgers books or other items of this web site for further developments.

The most common problem associated with long and irregular cycles is polycystic ovarian disease (this this item on this web site or in T Hilgers's book)
