The determination of the concentration of estrone-3-glucuronide and pregnanediol-3 alpha-glucuronide has been performed by a chemiluminescent immunoassay in early morning urine samples of 14 normal menstruating women and 11 women affected by luteal phase defect. The early morning urine samples were daily collected for an entire menstrual cycle. We have employed a timed and measured volume collection procedure as correction factor. The integrated values of the hormonal data in definite time intervals were used to create a nomogram. By means of this method, it was possible to completely separate normal from luteal insufficiency subjects and to distinguish two different types of luteal phase defects. Moreover, the same approach was applied to the study of the role and the frequency of luteal phase defect in 15 patients affected by habitual abortion and in 17 premenopausal women who had undergone quadrantectomy for T1a No Mo breast cancer. A luteal phase defect was detected in nine of the aborting patients (60%) and in eight women affected by breast cancer (47%). Finally estrone-3-glucuronide was measured in early morning urine samples of 96 prepubertal and pubertal girls in different pubertal stages and in one patient affected by precocious puberty, before and during an agonist GnRH treatment. The urinary test of ovarian function seems to be suitable for diagnostic purposes and for clinical studies.
