Abstract
Urinary estrone, estradiol–17β, estriol and pregnanediol were identified and measured during 3 normal menstrual cycles in 3 chimpanzees. During the first half of the menstrual cycle, the animals excreted 1–10 βg/day estrone, 0.5–5.0 βg/day estradiol–17β, 0.1–0.8 μg/day estriol, and < 20–700 Hg/day pregnanediol. In the second half of the cycle, corresponding values were 1–20 μg/day estrone, 1–9 μg/day estradiol– 17β, < 1.0–2.5 μg/day estriol, and Endocrinology91: 13, 1972)Keywords
