This article discusses Dr. Jane Hightower's findings on mercury poisoning linked to fish consumption in patients and reports no new clinical results; it highlights ongoing debate and regulatory actions.

This review discusses the cosmetic use and safety of Hypericum Perforatum Extract and Oil, finding that current data are insufficient to support their safety in formulations due to a lack of comprehensive testing.

This review discusses the etiology, diagnosis, and management strategies for hirsutism, noting that serious underlying disorders are rare and emphasizing targeted treatment to manage testosterone's effects.

This review examines recent advancements in green and emerging microextraction techniques, such as SPME and DLLME, for more sustainable hormone detection in biological samples, emphasizing environmentally friendly solvents and bioanalytical applications.

This study found that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

This study found that among Japanese full-time employees, cortisol levels in hair were negatively associated with aversive coping and emotional support-seeking tendencies, while dehydroepiandrosterone levels were linked to job confidence.

This study found that in male rats, hesperidin co-administration ameliorated finasteride-induced testicular toxicity by reducing oxidative stress and improving antioxidant status, sperm parameters, and enzyme activity compared to finasteride treatment alone.

This study found that a hypomorphic mutation in the Hr gene contributes to the development of diet-induced pruritic atopic skin in mice, particularly when combined with dietary deficiencies of polyunsaturated fatty acids and starch.

This study found that the Bioengineered Exosomal Hair Growth Factors Complex (BEHC™) enhanced human follicle dermal papilla cell proliferation and reduced inflammatory markers in vitro, while significantly decreasing hair shedding and increasing hair density among participants with androgenetic alopecia in an open-label clinical study.

In this study of hirsute women, researchers found that correlations between hirsutism and hyperandrogenism were observed only in patients with a low LH/FSH ratio.

This study found that mutations in exon 3 of the hr gene are strongly associated with congenital hypotrichosis in Valle del Belice sheep, suggesting a potential genetic link to the disorder.

This study observed that mice with a whole-body deficiency of Cystathionine-β-synthase developed severe hyperhomocysteinemia and related mild symptoms without increased mortality, indicating HHCy may not directly cause end organ damage.

This study found that human placental extract significantly improved melasma, chronic ulcers, and alopecia areata without major adverse effects, suggesting its effectiveness and safety for these conditions.

This review explores the evaluation and treatment of hirsutism, emphasizing a systematic approach to uncovering its causes and recommending combination therapies for effective management, but presents no new results.

This review discusses the genetic basis of ectodermal dysplasia, highlighting that identification of gene pathologies enhances diagnosis and supports prenatal DNA testing, but it reports no new clinical results.

This publication reviews the World Professional Association for Transgender Health's Standards of Care for supporting transgender and gender nonconforming people, with adjustments needed for diverse global contexts and no new clinical results.

This study concluded that combined hormonal contraceptives containing desogestrel, drospirenone, or cyproterone acetate were associated with a higher risk of venous thromboembolism compared to those containing levonorgestrel.

This integrative review found that while hormone therapy, under proper medical supervision, can improve quality of life by treating conditions like muscle and bone mass loss, using these hormones without clinical need poses serious risks to neurological, cardiac, hepatic, renal, and reproductive health.

This study found that sebaceous glands predominantly exhibit oxidative activity of the type 2 17β-hydroxysteroid dehydrogenase isozyme, which is not inhibited by 13-cis retinoic acid.

This review discusses idiopathic hirsutism, potential underlying mechanisms, and various therapeutic approaches without providing new clinical results, and emphasizes the need for further research on well-defined patient groups.

This study found that Hibiscus rosa-sinensis leaf extract promoted hair growth in rats more effectively than its flower extract, suggesting its potential as a natural alternative for hair growth treatments.

This study highlights that hirsutism in women, most commonly caused by polycystic ovary syndrome, should be evaluated with tools like the Ferriman–Gallwey score and total testosterone measurements, and managed using methods like hair removal and combined oral contraceptives when fertility preservation is not a priority.

This article reviews the potential relationship between serum amyloid A and hidradenitis suppurativa, highlighting genetic influences, but reports no new clinical findings.

This case report describes the treatment of hirsutism in a 15-year-old obese Mexican girl with flutamide, aiming to improve her social function.
