research The Effect of 5α-Reductase Inhibition with Dutasteride and Finasteride on Semen Parameters and Serum Hormones in Healthy Men
Dutasteride and finasteride may reduce sperm count and volume but don't affect movement or shape; effects are reversible after stopping.
research Effects of Sex Steroid Deprivation/Administration on Hair Growth and Skin Sebum Production in Transsexual Males and Females
Hormone treatments in transsexual individuals reduce hair growth and oil production in male-to-females and increase them in female-to-males.
research Dihydrotestosterone-Inducible Dickkopf 1 from Balding Dermal Papilla Cells Causes Apoptosis in Follicular Keratinocytes
A substance called DKK-1 increases in balding areas and causes hair cells to die when exposed to DHT.
research There is no clear association between low serum ferritin and chronic diffuse telogen hair loss
Low iron levels are not directly linked to chronic hair loss and iron supplements may not help.
research The importance of adequate serum ferritin levels during oral cyproterone acetate and ethinyl oestradiol treatment of diffuse androgen-dependent alopecia in women
Having enough iron improves the effectiveness of a specific hair loss treatment in women.
research Mast cell deficient and neurokinin-1 receptor knockout mice are protected from stress-induced hair growth inhibition
Certain mice without specific receptors or mast cells don't lose hair from stress.
research The Effect of 5α-Reductase Inhibition With Dutasteride and Finasteride on Bone Mineral Density, Serum Lipoproteins, Hemoglobin, Prostate Specific Antigen and Sexual Function in Healthy Young Men
Dutasteride and finasteride do not significantly affect bone density, blood fats, or blood production, but slightly lower PSA levels and minimally impact sexual function in healthy young men.
research The Therapeutic Effect and the Changed Serum Zinc Level after Zinc Supplementation in Alopecia Areata Patients Who Had a Low Serum Zinc Level
Zinc supplements increased zinc levels in some hair loss patients but didn't significantly improve hair growth.
research Serum Ferritin and Vitamin D in Female Hair Loss: Do They Play a Role?
Low iron and vitamin D levels are linked to hair loss in women.
research The Inflammatory Caspases-1 and -11 Mediate the Pathogenesis of Dermatitis in Sharpin-Deficient Mice
Certain proteins, caspases-1 and -11, are important in the early development of skin inflammation in mice.
research No Association between Serum Ferritin Levels >10 μg/l and Hair Loss Activity in Women
Higher iron levels in the blood are not linked to increased hair loss in women.
research Bacteria induce skin regeneration via IL-1β signaling
Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.
research LY191704: a selective, nonsteroidal inhibitor of human steroid 5 alpha-reductase type 1.
LY191704 is a compound that effectively blocks a specific enzyme involved in hormone conversion and could help treat enlarged prostate and hair loss.
research Selective non-steroidal inhibitors of 5α-reductase type 1
Selective non-steroidal inhibitors of 5α-reductase type 1 can help treat DHT-related disorders.
research Tight Junction barriers in human hair follicles – role of claudin-1
Claudin-1 is important for the barrier function and growth of hair.
research Autoimmune polyendocrine syndrome type 1: an Italian survey on 158 patients
APS-1 in Italy shows diverse AIRE mutations and various autoimmune issues.
research Deficient Plakophilin-1 Expression Due to a Mutation in PKP1 Causes Ectodermal Dysplasia-Skin Fragility Syndrome in Chesapeake Bay Retriever Dogs
A PKP1 gene mutation causes skin fragility and hair loss in Chesapeake Bay retriever puppies.
research The mRNA for Protease Nexin-1 is Expressed in Human Dermal Papilla Cells and its Level is Affected by Androgen
Human skin cells contain Protease Nexin-1, and male hormones can decrease its levels, potentially affecting hair growth.
research Icariin promotes mouse hair follicle growth by increasing insulin-like growth factor 1 expression in dermal papillary cells
Icariin helps mouse hair grow by boosting a growth factor in skin cells.
research Pharmacokinetic parameters and mechanisms of inhibition of rat type 1 and 2 steroid 5α-reductases: determinants for different in vivo activities of GI198745 and finasteride in the rat 3 3Abbreviations: r5AR1, rat 5α-reductase 1; r5AR2, rat 5α-reductase 2; and DHT, dihydrotestosterone.
GI198745 is more potent and longer-lasting than finasteride, potentially better for treating hair loss.
research Comparison of Zn, Cu, and Fe Content in Hair and Serum in Alopecia Areata Patients with Normal Group
Hair and serum levels of zinc, copper, and iron are similar in people with alopecia areata and healthy individuals.
research Decreased lipin 1β expression in visceral adipose tissue is associated with insulin resistance in polycystic ovary syndrome
Lower lipin 1β in belly fat is linked to insulin resistance in people with polycystic ovary syndrome.
research 17β-Estradiol Enhances Vascular Endothelial Growth Factor Production and Dihydrotestosterone Antagonizes the Enhancement via the Regulation of Adenylate Cyclase in Differentiated THP-1 Cells
Estrogen increases blood vessel growth factor production, while testosterone blocks this increase.
research Serum drug level-related sodium valproate-induced hair loss
High levels of the seizure medication sodium valproate can cause hair loss.
research A model system for long-term serum-free suspension organ culture of human fetal tissues: experiments on digits and skin from multiple body regions
Scientists developed a method to grow human fetal skin and digits in a lab for 3-4 weeks, which could help study skin features and understand genetic interactions in tissue formation.
research Antiandrogen Drugs Lower Serum Prostate-Specific Antigen (PSA) Levels in Hirsute Subjects: Evidence That Serum PSA Is a Marker of Androgen Action in Women1
Antiandrogen drugs can reduce PSA levels in women with excess hair, suggesting PSA is a sign of male hormone activity in women.
