To investigate the usefulness of a semi-quantitative assay of urinary luteinizing hormone (LH) for predicting ovulation, the relationship among urinary LH, serum LH, serum estradiol (E2) and ultrasonographic observations of follicles were examined in 32 infertile women (35 cycles) at spontaneous (7), clomiphene (13) or cyclofenil (3) induced or hMG (12) induced cycles. Their urine samples were collected 3 times a day for LH assay, starting from about the 10th cycle day or when follicles having a diameter of 10mm or more were detected to the day of ultrasonographical confirmation of follicle ruptures. In the morning on these days, blood was taken twice daily for LH and E2 determination at intervals of 30 min. In spontaneous cycles, urinary LH was (P < 0.001) correlated to a significant extent with the serum LH and E2 levels, and follicle rupture was observed 1.9 days after the urine LH surge. In contrast, there was no significant correlation between the urine LH and serum LH or E2 levels in the ovulation induced cycles. In addition, the period from urine LH positive to follicle rupture was significantly (P < 0.05) prolonged in those cycles compared with that in spontaneous cycles. These results suggested that the urine LH determination was good for predicting ovulation in spontaneous cycles, but it was also necessary to monitor the follicle sizes by ultrasonography in ovulation induced cycles.
