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 Diagnosis of hyperandrogenism: Biochemical criteria
The document concludes that accurate measurement of serum androgens is crucial for diagnosing hyperandrogenism.
research Parathyroid Hormone-related Protein in Normal and Neoplastic Canine Tissues: Immunohistochemical Localization and Biochemical Extraction
PTHrP is higher in certain dog tumors and may act as a local growth factor.
research Asymptomatic hyperprolactinemia resulting from macroprolactemia
Some patients with high prolactin levels don't show symptoms because they have a form of the hormone that's less active.
research Androgens in Women – Critical Evaluation of the Methods for Their Determination in Diagnostics of Endocrine Disorders
The conclusion is that standardizing testosterone measurement methods is essential for better diagnosis accuracy in women.
research Effect of cosmetic hair treatment and natural hair colour on hair testosterone concentrations
Cosmetic hair treatments can increase hair testosterone levels, while natural hair color does not affect it.
research Segmental hair analysis - a retrospective testosterone diary?
Hair analysis can somewhat track past testosterone levels but is influenced by factors like hair washing, growth rate, sex, and hair color.
research SERUM-CONCENTRATIONS OF Dehydroepyandrosterone-sulfate IN MEN WITH ANDROGENETIC ALOPECIA
Men with hair loss don't necessarily have higher levels of the hormone DHEA-S, but this hormone tends to decrease with age.
research Human Skin is a Steroidogenic Tissue: Steroidogenic Enzymes and Cofactors Are Expressed in Epidermis, Normal Sebocytes, and an Immortalized Sebocyte Cell Line (SEB-1)
Human skin can produce steroids from cholesterol.
research Prenatal serological diagnosis of intrauterine cytomegalovirus infection.
Blood tests confirmed a baby in the womb had a CMV infection.
research Prevention of doxorubicin-induced alopedia by scalp hypothermia: relation to degree of cooling.
Cooling the scalp below 22°C before and during chemotherapy can help prevent hair loss.
research In vitro bioassays for androgens and their diagnostic applications
In vitro bioassays are better than traditional methods for measuring androgen activity but aren't ready for routine use yet.
research Salivary testosterone levels in infertile men
Men with low or no sperm count have lower salivary testosterone levels, and saliva testing can measure their testosterone well.
research Relations between sex hormone level and characters of hair and skin in healthy young men
Higher androgen levels do not cause baldness in men.
research Hyperandrogenism from an Ovarian Interstitial-Cell Tumor in an Alpaca
An alpaca acted like a male and couldn't have babies because of a benign tumor in its ovary that caused high testosterone levels.
research PLASMA TESTOSTERONE GLUCOSIDURONATE: A RELIABLE INDICATOR OF FEMALE HYPERANDROGENISM (IDIOPATHIC HIRSUTISM AND ANDROGENIC ALOPECIA)
Measuring plasma testosterone glucosiduronate is a reliable way to detect high male hormone levels in women.
research Acne in hirsute women
Hormonal treatments like birth control pills can improve acne in women with excess hair growth and hormone imbalances.
research Measurement and comparison of various androgen levels in women with severe acne, hirsutism, and androgenic alopecia
Women with severe acne, hirsutism, and androgenic alopecia often have higher levels of certain androgens, but the specific pattern can't be predicted just by looking at symptoms.
research Relationship between plasma sex hormones and severity of coronary artery disease
Lower testosterone levels in men may be linked to a higher risk of severe coronary artery disease.
research Androgen excess: Investigations and management
The conclusion is that managing androgen excess requires long-term treatment, including hormonal contraceptives and androgen blockers, with follow-up after six months.
research Role of androgens in female-pattern androgenetic alopecia, either alone or associated with other symptoms of hyperandrogenism
Androgens significantly affect female hair loss, and hormonal treatments may help.
research Progesterone-induced stimulation of mammary tumorigenesis is due to the progesterone metabolite, 5α-dihydroprogesterone (5αP) and can be suppressed by the 5α-reductase inhibitor, finasteride
Progesterone byproduct 5αP stimulates mammary tumor growth, but finasteride can suppress it.
research Serum C-19 steroid sulphates in females with clinical hyperandrogenism
Women with hyperandrogenism have higher androgen levels and lower SHBG, which may contribute to conditions like excessive hair growth and early puberty.
