This study identified numerous genes that change expression across the anagen, catagen, and telogen stages of cashmere goat hair follicle development, highlighting key signaling pathways involved.

This study defined menstrual phase-specific reference intervals for circulating androgen levels in young women, highlighting that anovulatory females showed higher androgen, LH, and FSH levels compared to ovulatory females.

This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

Seborrhea in Parkinson's disease may be linked to hormones, not autonomic impairment.

The document concludes that identifying the cause of amenorrhea is crucial for proper treatment.

This article is a letter to the editor discussing the treatment of telogen effluvium using a dietary supplement, but it provides no new research results.

This review discusses how the brain can influence skin biology, suggesting a link between psychological factors and skin health, but it reports no new scientific findings.

This study found that in mink, the pituitary gland is essential for normal seasonal pelage cycles, and manipulating hormone levels can affect hair growth and type.

Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.

This case report identified UVB photosensitivity and testicular failure as previously unreported components of low-sulfur hair syndrome in a 16-year-old male.

This study suggests that many men with premature balding exhibit a hormonal pattern similar to some aspects of polycystic ovary syndrome in women.

This article reviews the effect of aging on male hormone levels and fertility, highlighting the need for more research on the benefits and risks of androgen supplementation in older men.

This study suggests that hormonal changes may contribute to the persistent symptoms of long COVID, with specific patterns observed in serum hormone levels related to fatigue and sensory dysfunction.

This study reported that both drospirenone and chlormadinone acetate oral contraceptives had similar beneficial effects on clinical, metabolic, and hormonal parameters in women with polycystic ovary syndrome over six months.

In this study, decreased levels of SHBG and a high free androgen index were observed in men with severe premature baldness compared to controls, but this condition was not equivalent to PCOS or metabolic syndrome in females.

Hair loss is often linked to thyroid problems, especially in women and older people, and screening for thyroid issues is advised for those with hair loss.

This case report documents an instance of symptomatic hypothyroidism developing in a patient with papillary thyroid carcinoma after beginning treatment with orlistat.

Amenorrhea, or the absence of periods, should be evaluated by age 15 or within five years of early breast development, and is most commonly caused by conditions like polycystic ovary syndrome and hypothalamic amenorrhea.

In this study, treatment with flutamide combined with a low-dose oral contraceptive significantly improved hirsutism in women with polycystic ovarian disease who did not respond to oral contraceptive treatment alone.

This study found that combined Myo-inositol and D-chiro-inositol therapy improved metabolic and hormonal parameters, including weight, hormone levels, and skin conditions, in women with PCOS after 6 months.

This meta-analysis found that in postmenopausal women with a history of breast cancer, 8 weeks of vaginal estrogen therapy while on aromatase inhibitors did not result in systemic absorption of sex hormones, suggesting potential safety for treating vulvovaginal atrophy in this context.

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 case series describes six women with both PCOS and Graves' disease, suggesting a possible shared underlying cause for their co-occurrence.

This study reports that in ovarian cell development, FSH-induced OCT4 expression is regulated through the GSK3β/β-catenin pathway mediated by the PI3K/Akt pathway.

In this study, women with polycystic ovary syndrome had higher body mass index and hormone levels compared to healthy women, with hyperandrogenism symptoms like hirsutism and alopecia more prevalent among the obese participants.

TSH influences keratin expression in human hair follicles.

This report highlights a case where a woman's use of the dopamine agonist pramipexole for Parkinson's disease was associated with hair loss, which improved after discontinuing the drug.

This study found that while isotretinoin lowered levels of female hormones in patients with severe acne, it did not significantly impact ovarian reserve function.

This study suggests that some men with premature androgenic alopecia may have hormonal profiles similar to women with polycystic ovary syndrome, potentially indicating a male equivalent of the condition.

This study used a glucocorticoid-injection model to mimic kidney-yang deficiency syndrome and reported symptoms related to hormonal imbalances in the hypothalamic-pituitary-target gland axes.
