Determination of urinary luteinizing hormone for prediction of ovulation

Detection of the approximate time of ovulation is important in the in vitro fertilization-embryo transfer programs in order to avoid a possible early surge of luteinizing hormone (LH) before human chorionic gonadotropin administration in the induction of ovulation and for timing of artificial insemination. In the present study correlation between the detection of LH in urine and serum levels (mean ± SEM) of estradiol >557 ± 118pg/ml, progesterone < 1.9 ± 0.37 ng/ml and leading follicle diameter >26.2 ± 1.3 mm (mean ± SEM) was found. Thus, the prediction of ovulation via detection of urinary LH in urine by a dipstick procedure is a good semiquantitative method, accurate enough, reliable, cheap and acceptable by the women.
