Urinary estrogen profiles were made on 6 women, aged 26-30 years. Mean values of excreted estrone (E1) were the highest values in the 1st half of the cycle: 10.15 in the follicular phase and 10.23 mcg/24 hours in midcycle. In the 2nd half of the cycle the level of E1 decreased: 8.78 in the early luteal phase and 8.36 in the late luteal phase. Estradiol (E2) showed its highest mean level in the midcycle, 4.53 mcg, 2.80 in the follicular phase, 3.95 mcg in the early luteal phase, and 3.38 mcg in the late luteal phase. Estriol (E3) showed its lowest levels in the follicular phase at 13.78 mcg and in the late luteal phase at 14.12 mcg/24 hours. The highest E3 levels were 17.59 mcg in midcycle and 17.33 mcg/24 hours in the early luteal phase. The mean quotient ratio of E3/E1+E2 (R) showed high estriol proportions of 1.1, 1.2, 1.4, and 1.2 in all consecutive cycle phases. These are noted to be higher than those of English women (.70 and 1.21 in the 1st and 2nd phases). The racial and geographical factors involved in this are examined.
