Calculation of bioavailable and free testosterone in men: a comparison of 5 published algorithms.
BACKGROUND Estimation of serum concentrations of free testosterone (FT) and bioavailable testosterone (bioT) by calculation is an inexpensive and uncomplicated method. We compared results obtained with 5 different algorithms. METHODS We used 5 different published algorithms [described by Sodergard et al. (bioTS and FTS), Vermeulen et al. (bioTV and FTV), Emadi-Konjin et al. (bioTE), Morris et...
متن کاملInterrelationships of serum testosterone and free testosterone index with FFM and strength in aging men.
Muscle mass and strength losses during aging may be associated with declining levels of serum testosterone (T) in men. Few studies have shown a direct relationship between T and muscle mass and strength. Subjects were 262 men, aged 24-90 yr, from the Baltimore Longitudinal Study of Aging, who had T and sex hormone-binding globulin sex hormone-binding globulin (SHBG) measurements, from which the...
متن کامل[Free testosterone index: comparison with plasma free testosterone].
Blood-free testosterone indices were measured among 28 normal men (age; 24-48 yrs.), 20 normal women (20-36 yrs.), 18 pregnant women (22-31 yrs.), 17 males with hypogonadism (23-56 yrs.), 17 males with chronic hepatitis (20-42 yrs.), 24 males with liver cirrhosis (29-68 yrs.), 34 males with hyperthyroidism (20-42 yrs.) and 7 hirsute women (18-31 yrs.), and these were compared with the plasma co...
متن کاملValidity of serum testosterone, free androgen index, and calculated free testosterone in women with suspected hyperandrogenism.
OBJECTIVES There are technical limitations for the currently available methods of measuring serum total and free testosterone in females. The study objectives were to evaluate the usefulness of serum total testosterone, sex hormone-binding globulin (SHBG), free androgen index (FAI), and calculated free testosterone (CFT) in the assessment of androgen status in women investigated for suspected h...
متن کاملFree testosterone and risk for Alzheimer disease in older men.
OBJECTIVE To investigate the relationships between age-associated decreases in endogenous serum total testosterone (T) and a free T index (FTI) in men and the subsequent development of Alzheimer disease (AD). METHOD The authors used a prospective, longitudinal design with follow-up in men since 1958. Participants were from the Baltimore Longitudinal Study of Aging, a community-dwelling volunt...
