THE BIOGENESIS OF PRIMARY SEX HORMONES

The Biogenesis of Primary Sex Hormones

1. A method is given for the extraction and fractionation of rabbit urines which frees these urines of inactive chromogens but permits a quantitative recovery of estrone and estriol for the colorimetric determination of these compounds. 2. Estrone and estriol content of rabbit urine extracts can be determined by the concentration of the colored compound they form upon diazotization with sulfani...

Effect of sex hormones on bone in primary osteoporosis.

The effect of sex hormones on bone tissue was studied in 12 osteoporotic patients. Surfaces of bone undergoing formation and resorption were determined by quantitative microradiography of iliac crest biopsy samples before and after treatment with estrogens in 11 postmenopausal women and with testosterone in one gonadally competent man. Before treatment, bone resorption was greater than normal i...

The Male Sex Hormones

The general effects of castration, in addition to the loss of spermatogenesis, have been known since our earliest historical records. It is not the purpose of this paper to review the earlier studies which emphasize the effects of castration of the male, of transplantation of gonads, and of cryptorchidism on the various physiological, psychical, morphological, and histological changes in the bo...

Sex Hormones of Females

The correlation of anandamide with gonadotrophin and sex steroid hormones during the menstrual cycle

Objective(s): The purpose of this study was to investigate the change in plasma anandamide (AEA) levels throughout the normal menstrual cycle, and to analyze the relationship among AEA, sex steroids and gonadotrophins. Materials and Methods: The patients were fertile women with normal menstrual cycle, proposed to get in vitro fertilization (IVF) treatment due to oviduct obstruction or male infe...
