Androgens, insulin-like growth factor-I (IGF-I), and carrier proteins (SHBG, IGFBP-3) in postmenopause.

Objective: To determinate the profile of androstenedione (A), total (T), and free testosterone (FT), dehydroepiandrosterone (DHEA), DHEA-sulphate (DHEAS), sex hormone-binding globulin (SHBG), insulin-like growth factor-I (IGF-I) and IGF-binding protein-3 (IGFBP-3) in non-smoking, postmenopausal women of normal weight and to search for correlations between hormones and carrier proteins and chronological age, number of years of postmenopause and age of onset of menopause.

Design: A group of 149 postmenopausal women aged 49 to 74 years were divided into three groups based on the number of years of postmenopause: 2-4 years (group A), 9-12 years (group B), and 19 years or more (group C). Seventy-two women aged 21 to 35 years were the controls.

Leptin in functional hypothalamic amenorrhoea.

Background: Leptin, body weight, body mass index (BMI) and other hormones in women with functional hypothalamic amenorrhoea (FHA) were investigated and the hypothesis proposed that energy imbalance is the predominant mechanism for leptin reduction in patients with FHA.

Methods: Eighty-eight women with FHA and 65 age- and weight-matched controls were divided into homogeneous groups on the basis of their BMI: women with different degrees of underweight (BMI 15-16, 17-18 kg/m(2)) and of normal weight (BMI 19-21, 22-24 kg/m(2)). Hormone and carrier protein assays were measured in all groups.

Long-term follow-up of functional hypothalamic amenorrhea and prognostic factors.

This study evaluated the prognosis of functional hypothalamic amenorrhea (FHA) and the predictive factors of recovery, through a long-term follow-up. Ninety-three women affected by FHA underwent a follow-up for an average period of 8.1 yr (range 7-9 yr).
