Abstract
Summary
This study demonstrates that the function of both ovarian and uterine weight response to pituitary extract and to prolan follows the same type of curve, namely, logistic curves. However, they differ from each other markedly in the numerical values of their constants, among which the value of d + k is the most noteworthy. This defines the average maximum weight response attainable under the specified conditions. It is much higher in the case of ovaries, but lower in the case of uterus when pituitary extract is given, compared with prolan. The ovarian weight curve with pituitary extract may be of interest in assay.
We wish to express our thanks to Dr. H. B. van Dyke for suggestions in preparing pituitary gonadotropic extracts, to Dr. I. C. Yuan and Mr. C. S. Hsieh for help in mathematical analysis, and to Mr. C. Y. Chou for the chemical determination of sex hormones in prolan.
