In post-menopausal women, signs of increased male hormones should be checked for possible ovarian cancer.
research Hair Cortisol as a Biomarker of Chronic Stress in Community-Dwelling Adults With Longstanding Multiple Sclerosis
Hair cortisol levels don't reliably indicate chronic stress in people with multiple sclerosis.
research Recent advances in the molecular mechanisms causing primary generalized glucocorticoid resistance
Mutations in the NR3C1 gene cause a rare condition that affects hormone signaling and can lead to various symptoms, with dexamethasone as a treatment option.
research Quantifying long-term stress in brown bears with the hair cortisol concentration: a biomarker that may be confounded by rapid changes in response to capture and handling
Hair cortisol levels in brown bears can be affected by both long-term and short-term stress.
research MON-336 Ovaries Reveal Their Inner Testes
A woman's severe male-like symptoms were caused by a rare, benign tumor in her ovary that produced male hormones.
research Menopausal Androgen Excess - Associated Cardio-Metabolic Risk: Clues for Ovarian Leydig Cell Tumour (Case Report and Mini-Review of Literature)
High androgen levels in postmenopausal women may suggest an ovarian tumor, and removing it can improve heart and metabolic health.
research The evaluation and treatment of androgen excess
High androgen levels can cause excessive hair growth and may indicate serious health issues, including heart disease and fertility problems.
research Alopecia in preexisting autoimmune thyroid disease in family medicine practice: can hyperprolactinemia induce hair loss? A case report
High prolactin levels might be linked to hair loss in autoimmune thyroid disease, but more research is needed.
research Children’s hair cortisol and hair testosterone concentrations in response to environmental changes: from summer holidays to school
Girls had higher stress hormone levels during school due to social and emotional issues, while boys had higher overall hormone levels with slight changes when school started.
research Parity-related variation in cortisol concentrations in hair during pregnancy and in the postpartum period: a prospective cohort study
First-time mothers had higher stress hormone levels in late pregnancy than mothers who had given birth before.
research Radiolabel validation of cortisol in the hair of rhesus monkeys
Hair cortisol can indicate long-term stress levels, but hair growth rate differences may affect accuracy.
research An ovarian Leydig cell tumor of ultrasound negative in a postmenopausal woman with hirsutism and hyperandrogenism
A postmenopausal woman's hirsutism and high testosterone levels improved after surgery for an ovarian tumor not seen on ultrasound.
research Hiperandrogenismo avanzado en una mujer postmenopáusica: Caso clínico
A postmenopausal woman's high testosterone levels and symptoms improved after removing a tumor from her ovary.
research Serum and hair steroid profiles and their associations with body composition in adolescence
Hair steroid profiling is a feasible, non-invasive alternative to serum analysis for assessing hormone levels and metabolism.
research Influence of external factors on hair cortisol concentrations
External factors can significantly affect hair cortisol levels, so it's not always a reliable stress marker.
research Hair cortisol concentrations in mental disorders: A systematic review
People with depression often have higher hair cortisol levels, while those with PTSD tend to have lower levels, but more research is needed to understand this fully.
research Within-person changes of cortisol, dehydroepiandrosterone, testosterone, estradiol, and progesterone in hair across pregnancy, with comparison to a non-pregnant reference group
Hormone levels in hair change during pregnancy, with progesterone increasing significantly compared to non-pregnant women.
research Exploring Reference Values for Hair Cortisol
Hair sample weight is a better measure for cortisol levels in hair than hair protein concentration.
research Longitudinal association between saliva and hair cortisol concentration: A systematic comparison
Hair cortisol is a reliable marker of long-term cortisol levels and is linked to daytime saliva cortisol but not morning levels.
research The impact of COVID-19 pandemic and lockdown on chronic stress assessed by hair cortisol analysis via LC-MS/MS
Chronic stress increased after lockdown, especially in young adults and females.
