FIGURE 1 Frequency distributions in 20 menstrual cycles of the days of peak hormone concentrations and the DLTs as determined by two algorithms. The data are aligned to the day of follicular collapse (day 0) as determined by serial ultrasonography. Li. Estimating the day of ovulation. Fertil Steril 2002.
