Abstract

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.
