Methods used to self-predict ovulation. A comparative study

J Obstet Gynecol Neonatal Nurs. 1990 May-Jun;19(3):233-7. doi: 10.1111/j.1552-6909.1990.tb01642.x.


Time of ovulation as detected by a self-test of luteinizing hormone (LH) in the urine was compared with time of ovulation as detected by self-observation of cervical mucus. Twenty regularly cycling women monitored their cervical mucus and urine LH for two complete menstrual cycles. Of the cycles that had an LH surge, 100% were on the peak day of cervical mucus or within three days before the peak day. Self-observation of cervical mucus, therefore, can be an accurate method of determining optimal fertility.
