Concentrations of triglycerides are increased and concentrations of high-density lipoprotein (HDL) cholesterol are low in women with hyperandrogenism. These alterations could be related to excessive androgen or estrogen, to hyperinsulinism, or to a combination of these abnormalities. We examined

Diurnal rhythm and effects of oral contraceptives on serum dehydroepiandrosterone sulfate (DHEAS) are related to alterations in serum albumin rather than to changes in adrenocortical steroid secretion.

Dehydroepiandrosterone sulfate (DHEAS), which is of almost exclusive adrenal origin, is important for the androgen status in women and prepubertal children, and DHEAS assays are used in the investigation of hyperandrogenism. There are conflicting reports concerning a diurnal variation in serum

Non-sex hormone-binding globulin-bound testosterone as a marker for hyperandrogenism.

Recent evidence suggests that the biologically active testosterone includes both the free and albumin-bound fractions, while the sex hormone-binding globulin (SHBG)-bound steroid dissociates less readily. To examine the significance of the non-SHBG-bound testosterone (i.e. free plus albumin bound)

BACKGROUND Sex hormones, particularly androgens, may influence not only adipose tissue distribution but also its functions. OBJECTIVE We aimed to evaluate if sexual dimorphism in body composition is accompanied by differences in the protein abundance of adipose tissue by applying a nontargeted

Free testosterone is the most common marker of hyperandrogenism in women. Its measurement by equilibrium dialysis and liquid chromatography-tandem mass spectroscopy is the "gold standard", but determination of free testosterone routinely not feasible in all laboratories. In some cases the level of

OBJECTIVE Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting approximately one in seven women who experience androgen excess, menstrual cycle irregularities, frequent anovulation and a tendency for central obesity and insulin resistance. Chronic subclinical inflammation is now

Hirsutism in women is defined as excessive facial and/or body terminal hairs showing a masculine distribution; the condition affects approximately 7% of women of reproductive age, and chronic anovulation is a common problem for infertile couples, with a rate of 20-25%. There is a general consensus

We compared the diagnostic value of information given by total testosterone (I), free testosterone (II), the free androgen index (III), and testosterone not bound by sex-hormone-binding globulin (SHBG) (IV) as measured by a new differential ammonium sulfate precipitation technique, each step of

BACKGROUND In unselected reproductive-aged women, use of combined estrogen-progestin oral contraceptive pills has been linked with an increased risk of vascular disease. The aim of this study was to investigate the effect of oral contraception on cardiometabolic risk factors in a population of women

The effects of spironolactone on testosterone fractions and sex-hormone binding globulin binding capacity in hirsute women.

This study explored the effect of the anti-androgen spironolactone on sex-hormone binding globulin (SHBG) and the distribution of circulating testosterone (T) into various free and bound fractions in seven women with hirsutism assessed before and then monthly for three months on a regimen of

Testosterone (T) concentrations in saliva and serum were measured in 53 women with various degrees of hirsutism and hyperandrogenism. The bioavailability of T was judged by comparing the correlations among the grade of hirsutism, salivary testosterone (SaT), and serum total and free T (fT) and sex

Individuals with non-classic congenital adrenal hyperplasia (NC-CAH) often show evidence of hyperandrogenism, including premature pubarche, accelerated linear growth velocity, short final height, hirsutism, acne, alopecia, impaired ovulation, menstrual dysfunction and subfertility.

Fifty-one hyperandrogenic women had their lipoprotein lipid profiles determined. Free and albumin-bound testosterone was associated with triglycerides and with high-density lipoprotein cholesterol independent of fasting insulin levels, percent ideal body weight, and waist/hip ratio. To gain insight

A radioimmunoassay for 21-deoxycortisol is described. The immunogen, 21-deoxycortisol-3-(0-carboxymethyl) oxime-bovine serum albumin, was prepared, the antisera raised against it were studied and the reliability of the assay was checked. The antiserum selected cross-reacted with 11-deoxycortisol

BACKGROUND Hyperandrogenism remains as one of the key features in Polycystic Ovarian Syndrome (PCOS) and can be assessed clinically or determined by biochemical assays. Hirsutism is the most common clinical manifestation of hyperandrogenism. The clinical assessment is subjected to wide variability
