测定了雌性绒猴（C. jacchus）围排卵期循环孕酮、雌激素和促黄体生成素（LH）水平。所有动物的黄体酮浓度在估计排卵日的1天内增加，证实了这种激素对排卵的回顾性检测的有用性。雌二醇- 17. - beta。和LH均显示出排卵前升高，但由于需要大量血浆（雌二醇：0.2 ml）和测定所需的时间（LH: 2-3天），测量这些激素对于预测排卵并不实用。未结合的雌酮在排卵前没有变化，但总雌酮（即结合的和未结合的）增加用于收集最近排卵的卵母细胞的时间。在5只动物中，有4只动物的雌酮3-硫酸水平在预期排卵期前至少1天升高。这种排卵前的上升可以很容易地通过快速直接测定来测量，从而为预测该物种的排卵提供了一种实用的方法。
Circulating progesterone, estrogens and LH [luteininzing hormone] were measured in female marmosets (C. jacchus) over the periovulatory period. Progesterone concentrations increased in all animals within 1 day of the estimated day of ovulation, confirming the usefulness of this hormone for retrospective detection of ovulation. Estradiol-17.beta. and LH both showed a preovulatory rise, but due to the large quantity of plasma required (estradiol: 0.2 ml) and the length of time taken for the assay (LH: 2-3 days), measurement of these hormones is not practical for the prediction of ovulation. There were no preovulatory changes in unconjugated estrone, but a rise in total (i.e., conjugated plus unconjugated) estrone was used to time the collection of recently ovulated oocytes. Levels of estrone 3-sulfate showed an increase at least 1 day before the expected day of ovulation in 4 out of 5 animals. This preovulatory rise can be measured easily by a rapid direct assay, thereby providing a practical method for predicting ovulation in this species.
