It is now well accepted by gynecologists that a woman can conceive from an act of intercourse for a maximum of seven days of her menstrual cycle [l]. The reliability of natural family planning methods depends on identifying this window of fertility without ambiguity. Several natural family planning (NFP) methods have been used extensively and with some success. For decades, cycle length and BBT history have been used to forecast the most likely days of ovulation. When greater precision is needed, serum LH assays or ultrasound techniques are used. With the recent development of enzyme-linked immunosorbent assay, various kits have become commercially available to provide a simple, self-administered, and rapid test for detection of the midcycle urinary LH surge . Some of these methods are fairly reliable and accurate. However, failures in these methods still occur, and some other problems concerning accuracy, simplicity, cost, and comfort have not been solved yet . In addition, other factors in NFP methods, such as the user, the procedure, and others, have been demonstrated to be important sources of errors.
