OBJECTIVE
The aim of this study is to compare the relationship between estrone (E1), estradiol (E2), androgens, and prolactin blood levels on the one hand, and endometrial thickness and related histopathologic results on the other, in postmenopausal women admitted with uterine bleeding.
METHODS

Plasma androstenedione (A) levels and plasma oestrone (E1) levels were measured by radioimmunoassay in a total of 135 healthy women (the control group), around the menopause. Both A and E1 plasma levels were found to drop significantly in the post-menopausal women (P less than 0.001). The mean

BACKGROUND
Medroxyprogesterone acetate (MPA)-treatment suppresses serum gonadotropin and androgen concentrations in women with polycystic ovarian disease (PCOD). This study was designed to determine serum testosterone (T), androstenedione (A) and luteinizing hormone (LH) patterns in a group of

The aim of the present study was to examine the effect of prolonged use of finasteride on serum levels of dihydrotestosterone (DHT), estradiol (E2), progesterone, testosterone and androstenedione in women during the menstrual period. Further, to screen and compare the 5α-reductase activities through

Postmenopausal women convert circulatory C19 steroids to estrogen. In order to study the possible role of such estrogen in endometrial cancer, the determination of the fractional conversion of circulation delta-4-androstene-3,17-dione to estrone was attempted. However, in the course of this work it

BACKGROUND
Increased adrenal androgen hormones in congenital adrenal hyperplasia (CAH) can rarely cause giant ovarian cysts in the neonatal period. Although the exact mechanism of the development of ovarian cysts is unknown, it is thought that increased androgen levels stimulate folicle development
Non-invasive measurement of 11-ketotestosterone, cortisol and androstenedione in male three-spined stickleback (Gasterosteus aculeatus).

The androgen 11-ketotestosterone (11-KT) plays an important role in reproductive physiology and behaviour in male teleosts. In the three-spined stickleback, Gasterosteus aculeatus, the plasma concentrations of 11-KT are related to the breeding status of the fish. Sticklebacks are relatively small
The aromatase inhibitor, 4-hydroxyandrostenedione, restores immune responses following trauma-hemorrhage in males and decreases mortality from subsequent sepsis.

Studies have shown that immune responses are depressed in male mice, but not in proestrus females after trauma-hemorrhage (TH), resulting in increased mortality from subsequent sepsis in male mice compared with female mice. These gender-specific alterations in immune function are believed to be due

The endocrinology of the perimenopause--the time between pre- and postmenopause--is characterized by changes in the metabolism of the steroid hormones caused by increasing insufficiency of the ovaries. Until the age of 48 the concentrations of the estrogens are relatively constant with a median
