THE FREE ANDROGEN INDEX AND MILD HIRSUTISM
Australasian Journal of Dermatology, 1986SummaryThe plasma testosterone was abnormal in only 11% of patients with mild hirsutism. However, a derived product, the free androgen index, was abnormal in 66% of cases and appears useful as a discriminating test.

The Free Androgen Index is not valid for adult males
The Journal of Steroid Biochemistry and Molecular Biology, 1993The Free Androgen Index (FAI) was initially proposed as a measure for assessing the circulating testosterone availability in female hirsutism. The extension of its use, by a number of investigators, to males has not been formally justified. An analysis of its derivation from the Law of Mass Action reveals an implied assumption that the binding capacity

The Apparent Free Testosterone Concentration, An Index of Androgenicity
The Journal of Clinical Endocrinology & Metabolism, 1971ABSTRACT As free non-protein bound testosterone is generally considered to represent the active androgen fraction in plasma, we developed a method, based on equilibrium dialysis of diluted plasma, by which the “apparent free testosterone concentration” (AFTC) in undiluted plasma is obtained. This AFTC was determined in normal adult, (pre)adolescent and

Free androgen index and Irisin in polycystic ovary syndrome
Journal of Endocrinological Investigation, 2015PCOS is associated with hyperandrogenism and insulin resistance (IR). Recent studies have shown that circulating Irisin levels increase in PCOS women. However, no report has demonstrated a relationship between Irisin and hyperandrogenism in PCOS women.

Calculated free testosterone in men: comparison of four equations and with free androgen index
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2006Background: Serum testosterone remains the most important investigation in the diagnosis of androgen deficiency in men. Most of the circulating testosterone is bound to albumin and sex hormone-binding globulin (SHBG), whereas free testosterone accounts for approximately 2% of total testosterone.

Journal of Tongji Medical University = Tong ji yi ke da xue xue bao, 1990
Hormone analyses for hirsute women suggested that free testosterone was most revealing in biological effects and sex-hormone-binding globulin (SHBG) was quantitatively persuative. Presented in this paper are the measurements of testosterone, androstendion, dehydroepiandrosterone-sulfate (DHAS), SHBG, androstandiol and free androgen index (FAI) in 51 ...

Fat-Free Mass Index in Users and Nonusers of Anabolic-Androgenic Steroids
Clinical Journal of Sport Medicine, 1995We calculated fat-free mass index (FFMI) in a sample of 157 male athletes, comprising 83 users of anabolic-androgenic steroids and 74 nonusers. FFMI is defined by the formula (fat-free body mass in kg) x (height in meters)-2. We then added a slight correction of 6.3 x (1.80 m - height) to normalize these values to the height of a 1.8-m man.

Plasma testosterone free index: A better indicator of plasma androgen activity?
Fertility and Sterility, 1975Testosterone, quantitatively the most important androgen in the circulation, must enter cells to exert an androgenic effect. It is accepted that it is that fraction of the hormone not bound to the specific, binding, beta-globulin which is available for entry into the cells.

17beta-ol androgens and free index in hirsute and hirsute obese women.
Fertility and sterility, 1976We have found the mean levels of combined serum testosterone and dihydrotestosterone (T+DHT) and the free index (FI) to be significantly higher and the mean dihydrotestosterone precipitation index (DHT-PI) to be significantly lower in hirsute women than in normal women.

Factors Influencing the Free Androgen Index in a Group of Subfertile Women with Normal Ovaries
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1988Eighty-five regularly cycling women with normal ovaries at laparoscopy, were studied to determine the factors that influence the free androgen index (FAI). It was found that body mass index (BMI), age of the patient and the phase of the menstrual cycle that the blood was collected can all affect the FAI. It is recommended that where possible, specimens
