1. A method of reducing the likelihood of conception during the human ovulation cycle by requiring the measurement of only urinary lutenising hormone (LH) concentration, which comprises, commencing on a predetermined day in the interval from numerical day 5 to numerical day 15 inclusive following the onset of menses, and at least 4 but not more than 8 days in advance of the numerical day corresponding to the day of detected LH surge in a previous cycle, performing frequent repeated daily testing of only urinary LH concentration until the LH surge associated with ovulation is detected, and avoiding unprotected intercourse during a time interval commencing on or before the first day of said repeated daily urinary LH concentration testing and ending at least 2 days following the day of LH surge detection.
