The aim of this study was to use measurements of urinary steroid glucuronides to confirm the suppression of ovulation of ovulation in women taking oral contraceptives. Urinary concentrations of ...oestrone-3-glucuronide (E1G) and pregnanediol-3 alpha-glucuronide (Pd-3-G) were measured by radioimmunoassay in early morning urine samples from six normally-menstruating women and six women who were taking combined oral contraceptives. In the normally-menstruating women, E1G concentrations, and the E1G/Pd-3-G ratio, increased 2-3 fold before ovulation. There was no midcycle increase in either measure in women taking oral contraceptives. We suggest that measurement of these steroid metabolites provides a means of assessing the anti-ovulatory effects of oral contraceptives.

The results show that the smoothness of the layers can be improved by adding controlled amounts of alloying materials, an effect that has already been observed for Ni/Ti supermirrors. Flipping ratios of more than 40 and reflectivities of more than 85% at twice the critical angle of Ni are obtained, depending on the concentrations of the materials,
