We studied 15 infertile patients for a total of 25 cycles in order to compare the predictive value of the following parameters in timing ovulation: basal body temperature (BBT), cervical mucus, serum E2 and LH, follicular growth as shown by ultrasonography, and urinary LH. The patients themselves tested urinary LH at home using Clearplan kits. BBT had low value as a predictive test for the time of ovulation, whereas ultrasonography had a predictive value of 9%, serum E2 50%, cervical mucus 59%, serum LH 63.6% and Clearplan kits 63.6%. The best predictive reliability in timing ovulation was obtained by considering both serum LH and E2 measurements. The Clearplan kits were as reliable as serum LH measurements and have greater practical advantages.
