This study found that shorter CAG-repeat lengths in the androgen receptor may be associated with the development of androgen-mediated skin disorders like androgenetic alopecia, acne, and hirsutism in both men and women.

This study suggests that androgen receptor gene CAG repeat length may influence serum free testosterone levels in some PCOS patients, with longer repeats associated with higher testosterone concentrations.

Finger length ratios are not linked to the number of specific gene repeats affecting testosterone sensitivity.

This study found that in women with polycystic ovary syndrome, shorter CAG repeat lengths in the androgen receptor gene were associated with lower dihydrotestosterone and androstenedione levels, but a higher prevalence of acne and hirsutism.

This study investigated a patient with spinal and bulbar muscular atrophy who had 68 CAG repeats, revealing early onset and unique symptoms not previously documented in the condition.

This review discusses the potential role of androgen receptor CAG repeat polymorphism testing in hypogonadism management for both sexes, but its clinical utility remains unclear and requires further investigation.

This study found no significant difference in the CAG and GGN repeat lengths between infertile and fertile men in Nigeria, but identified a unique GGN allele distribution in the Nigerian population compared to Caucasians.

This study found that the GGC repeat length significantly influenced testosterone levels in oral contraceptive users from high-risk breast cancer families, and homozygosity for short alleles may be linked to increased breast cancer risk.

This study found that the less common CAG-rs4045402 and GGN-rs3138869 polymorphisms were more frequent in patients with post-finasteride syndrome and androgenetic alopecia, suggesting a genetic predisposition to AGA development.

This study identified differences in adverse symptoms among patients with post-finasteride syndrome based on short and long androgen receptor gene polymorphisms.

In this study, the researchers reported that finasteride's efficacy in treating female pattern hair loss in Japanese patients was not predictable based on CAG repeat numbers in the androgen receptor gene.

This study suggests that longer GGN repeat polymorphisms in the androgen receptor gene are associated with polycystic ovary syndrome in women.

This study found that the count of CAG trinucleotide repeats in the androgen receptor gene may be associated with acne in female patients without hyperandrogenism.

This study found that, among fertile egg donors, the AR gene CAG polymorphism was associated with differences in antral follicle count but did not impact ovarian response to gonadotrophins.

This study found no significant difference in CAG repeat numbers of the androgen receptor gene between Han Chinese women with female pattern hair loss and healthy controls, suggesting it may not be a genetic marker for FPHL in this population.

This study did not find any correlation or linkage disequilibrium between androgen receptor gene CAG/GGC haplotypes and androgenetic alopecia in Mexican brothers.

This study found that a lower number of GGC sequences in the androgen receptor gene was associated with better clinical response to finasteride in male androgenetic alopecia patients.

This study found no significant link between the length of CAG repeats in the AR gene and the risk of polycystic ovary syndrome in Iranian women.

This study suggests that androgen receptor CAG polymorphisms may not significantly influence androgenetic alopecia susceptibility in Korean men.

This study found that variations in (CAG)n and (GGN)n polymorphisms in the androgen receptor gene appear to influence symptom severity in men with post-finasteride syndrome.

In this study, the researchers found no significant link between CAG repeat numbers in the androgen receptor gene and female pattern hair loss in a Chinese population.

This study suggests that variations in CAG repeat numbers in the androgen receptor gene may not significantly influence the risk of androgenetic alopecia in Korean males.

This retrospective study described the demographic characteristics, treatments, and prognosis of children with alopecia areata in a clinical setting, reporting a remission rate of 34.5% and highlighting the need for more comprehensive epidemiological data in this population.

This study found that for anterior cervical discectomy fusion in patients with degenerative cervical disc disease, the PEEK cage resulted in greater pain reduction, while the dynamic cervical implant maintained a slightly better range of motion.

This review describes the clinical, trichoscopic, and histopathological features of hair disorders linked to autoimmune diseases and reports no new clinical results.

This study found that specific genetic markers near the androgen receptor gene are significantly more common in men with male pattern baldness, suggesting a genetic component in its development.

This study found that serum androgen levels in premenopausal women may be influenced by genetic variants of the androgen receptor and estrogen receptor β genes.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This article discusses Kennedy's disease, detailing its genetic cause, symptoms, and diagnostic criteria, but reports no new clinical findings and highlights a lack of causal therapy.
