A genetic defect causes males in some Mediterranean populations to be born with ambiguous genitalia and develop male traits at puberty.
research Testosterone-like immunoreactivity in hair measured in minute sample amounts - a competitive radioimmunoassay with an adequate limit of detection
The new test can measure very small amounts of testosterone in hair, and grinding the hair up first gives more accurate results.
research Novel enzymatic assay predicts minoxidil response in the treatment of androgenetic alopecia
New test predicts if hair loss treatment will work.
research ODP423 Postmenopausal Virilization Secondary to A Rare Left Ovarian Androgen-Secreting Leydig Cell Tumor Localized Using Ovarian Vein Sampling
A woman's masculine symptoms were caused by a rare tumor in her left ovary, which was found using a special blood test.

Body hair can be used to test for alcohol intake, especially in men.
research Visual Vignette
The woman's symptoms and tests suggest her adrenal glands are producing too many male hormones.
research Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry
The study found that urine metabolites M1b or M4 are the best indicators of ATD use in horses, with detection possible up to 77 hours in urine and 28 hours in blood.
research Scalp hair 17‐hydroxyprogesterone and androstenedione as a long‐term therapy monitoring tool in congenital adrenal hyperplasia
Scalp hair 17-OHP and androstenedione levels can help monitor treatment in CAH patients.
research The presence of insulin resistance and comparison of various insulin sensivity indices in women with androgenetic alopecia.
Women with androgenetic alopecia (AGA) are more insulin resistant than healthy women, with various insulin sensitivity indices being higher in the AGA group. An oral glucose tolerance test is suggested for women with AGA.
research Hyperandrogenemia
research Estimation of serum aldosterone, free testosterone and DHEA-S and scalp androgen and aldosterone receptors in female androgenetic alopecia. Is the mystery solved?
High aldosterone and free testosterone levels link to female hair loss; testing aldosterone may predict hypertension risk.
research Urinary steroids in men with male-pattern alopecia
Men with male-pattern baldness have higher levels of certain testosterone metabolites and may have more active androgen metabolism.
research Determination of estradiol and progesterone concentrations in human scalp hair
Hair levels of estradiol and progesterone are higher in premenopausal than postmenopausal women, but the difference isn't statistically significant, indicating the need for a better measurement method.
research Comparison Between Two Different Hamster Models used for the Determination of Testosterone and Finasteride Activity
Young and adult hamsters both respond similarly to testosterone and finasteride treatments, but young hamsters aren't good for testing the inhibitory activity of a specific enzyme.
research A multi-centre, double-blind, randomised, vehicle-controlled study for a quantitative estimation of hair re-growth in male subjects with androgenetic alopecia treated over 6 month with two ethanolic PSK 3841 solutions (2.5% and 5%)
research The validation of estradiol extraction and analysis from hair
Hair can reliably measure average estradiol levels over months in humans and monkeys.
research Peripubertal Testosterone, 17β-Estradiol and Progesterone Concentrations in Hair and Nails in Dobermann Dogs
Hair and nails can show hormone changes during puberty in dogs.
research Markers of hyperandrogenism in South Asians with polycystic ovary syndrome
The FG score is better at detecting hyperandrogenism in PCOS patients than testosterone levels or FAI, but testosterone is the recommended test for diagnosis.
research A rare case of an androgen-producing stromal luteoma of the ovary in a postmenopausal woman, diagnosed by means of selective venous blood sampling
Doctors used a special blood sampling technique to diagnose a woman's rare ovarian tumor that was producing male hormones.
research Alterations in androgen conjugate levels in women and men with alopecia
Women with hair loss have higher androgen levels, while men with early balding have altered androgen ratios.
