This review provides a framework for diagnosing acquired scalp alopecias and discusses both non-scarring and scarring types, but reports no new clinical results.

This study reports that variable environmental factors, including dietary habits, may contribute to the increasing incidence and diverse clinical presentations of frontal fibrosing alopecia.

This article explores gender differences in lung cancer, noting a higher number of nonsmoking women over age 60 with lung cancer compared to men, and highlights potential hormonal and molecular influences; no new study results were presented.

This study found no significant difference in estrogen and progesterone receptor expression between androgenic alopecia and alopecia areata, suggesting an indirect hormonal influence on androgenic alopecia.

Men have worse COVID-19 outcomes than women due to genetic and hormonal differences.

This study found that women aged 21-26 with PCOS showed significant differences in biochemical and hormonal profiles, such as blood sugar and hormone levels, compared to healthy individuals, suggesting an increased incidence of PCOS in this age group.

This study found that PCOS patients with menstrual disorders exhibited hormonal changes and higher fasting glucose levels, despite no significant differences in insulin resistance markers.

In this study of women with PCOS in a rural setting, researchers observed no significant differences in hormonal or metabolic profiles based on age at menarche, but early menarche was associated with higher hirsutism, suggesting it could serve as an indicator of hyperandrogenism risk.

In this study, daughters of women with PCOS and control daughters showed no significant differences in metabolic and hormonal parameters, but more PCOS daughters exhibited hirsutism at advanced pubertal stages.

This study found that patients with alopecia areata had significantly higher serum T3 and cortisol levels compared to healthy controls, although both remained within normal ranges, highlighting potential hormonal involvement in the condition. However, no significant differences were observed in T4 and TSH levels.

This study concluded that while sex-related biological factors may influence COVID-19 outcomes, they do not fully explain the differences in mortality between women and men, underscoring the need for a gendered, intersectional approach to understanding health inequities and risk factors.

This study suggests that hormonal disturbances play a role in female pattern hair loss and that trichoscopy may be a useful tool for diagnosis and differentiation from other conditions.

This study suggests that hormonal receptor activity in skin regions undergoing mechanical stretching may influence extracellular matrix metabolism and the formation of SD, with variations in receptor functionality throughout lesion development stages.

This study found that women with acne resistant to conventional treatments had significantly higher levels of testosterone, DHEA‑S, prolactin, and LH, suggesting potential underlying hormonal disorders.

Women with excessive hair growth often have hormonal issues and need medical advice and treatment.

This review discusses how COVID-19 may affect gonadal function and potential gender differences, but reports no clinical results; it highlights possible mechanisms and new treatment approaches from recent literature.

This study reported that in women with pattern baldness, hormonal levels and iron deficiency were significantly associated with the condition, but trichoscopic findings were similar across different forms of female pattern hair loss.

This study found that increased hair growth from Cyclosporin A treatment is likely not due to hormonal changes.

This study found that women with polycystic ovarian syndrome at a gynecology clinic in Nnewi exhibited significant oxidative stress and hormonal imbalances compared to controls.

This study investigated hair fibre growth in Angora and Cashmere goats, finding differences in growth rates and seasonal dependencies, and examined the effects of prolactin and melatonin on protein deposition in hair follicles.

This review discusses female androgenic alopecia, highlighting its potential difference from male androgenic alopecia and notes increased incidence, but reports no new clinical findings.

This article reviews the congenital disorder aphallia, describing its rarity, clinical characteristics, and the normal hormonal and chromosomal profiles of affected individuals, but does not report new research findings.

This study observed that among a cohort of reproductive-aged women in the U.S., the prevalence of PCOS was about 4.0%, with no significant racial differences between White and Black women.

In this study, the prevalence of polycystic ovary syndrome in southern China was found to be 2.2%, with affected women showing distinct metabolic and hormonal characteristics compared to others.

In this study, low-dose finasteride (2.5 mg/day) significantly reduced hirsutism scores in women over 12 months without significant hormonal changes or serious side effects.

This study found that while male COVID-19 patients in Brazil exhibited more severe symptoms and required more intensive care than females, the difference in risk of death was relatively small.

This study found that metformin's metabolic benefits, such as reducing fat content and improving insulin sensitivity, were less pronounced in men with early-onset androgenic alopecia compared to those with normal hair growth, possibly due to differences in systemic inflammation and vitamin D status.

In this study, Pomeranians with non-illness, generalized alopecia did not exhibit adrenal or pituitary abnormalities, suggesting a breed-specific hormonal pattern as a potential cause rather than a functional adrenal anomaly.

This systematic review and meta-analysis found that male first-degree relatives of women with PCOS have increased rates of metabolic issues, hormonal imbalances, and androgenic features compared to controls, suggesting a male equivalent of PCOS.

This study reported that women with polycystic ovary syndrome had higher glypican-4 levels compared to controls, indicating its significant role in hormonal regulation associated with the condition.
