  • Method for determining periodic infertility in females
    Patent number: 5118630
    Abstract: A natural birth control method comprises observance of the first day of menses followed by measurement of urinary progesterone metabolite levels beginning a predetermined number of days after the first day of menses. Urinary progesterone metabolite measurement is performed on days of planned sexual activity until the concentration level exceeds a threshold value indicative of ovulation occurring more than 24 hours previously. Once such a threshold value is observed, the woman may discontinue testing and can consider herself unable to conceive until after the beginning of the subsequent menstrual cycle.
