Abstract
A rapid urinary luteinizing hormone (LH) test was used to plan a late luteal phase endometrial biopsy from 20 women undergoing an infertility evaluation. Histologic dating was correlated with the day of urinary LH surge detection, the day of the basal body temperature (BBT) nadir, and the onset of the next menstrual period (NMP). From 17 interpretable specimens, histologic dating correlated well with the day of the biopsy as determined following a positive LH test detection ( P = 0.079). No correlation was found following the BBT shift ( P = 0.65), and it was significantly correlated with the NMP ( P = 0.016). Moreover, the urinary LH test showed to be the best method to predict the onset of the NMP. These findings confirm urinary LH testing as a valuable adjunct in the investigation of luteal phase disorders.
