This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This study found that finasteride treatment in male rats may lead to changes in connexin 43 expression in the testes of their offspring, potentially affecting spermatogenesis.

This review discusses the role of androgens in hair follicle regulation and suggests that a better understanding could enhance treatments for conditions like hirsutism and alopecia, but does not present new findings.

This study found that testosterone replacement in castrated male rats counteracted endotoxemia-induced arterial baroreflex dysfunction without significantly affecting neuroinflammation.

This study found that nicotine may have a therapeutic role in mitigating the exacerbation of infertility conditions connected with alpha-synuclein-related Parkinson’s disease through molecular interactions identified via pathway analysis.

This study found that exposure to sex steroid biosynthesis inhibitors increases the expression of piRNA pathway genes in frog larvae, suggesting these genes play a role in gonadal sex differentiation.

In this study, researchers found that in mice, gonadal hormones and biological sex do not affect the expression of SARS-CoV-2 entry proteins ACE-2 and TMPRSS-2 in the respiratory tract, regardless of disease state.

This chapter reviews the potential role of gonadal hormones in sex differences in play and spatial behavior, noting a lack of conclusive evidence but suggesting perinatal androgen exposure might contribute to observed differences. It reports no new research results.

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 review examined genetic factors in 46, XY differences/disorders of sex development and found that whole-exome sequencing is more effective than panel sequencing for molecular diagnosis. It identified regional genetic variation and emphasized next-generation sequencing's role in detecting variants related to gonadal and androgen-related genes.

In this review, researchers explored key mechanisms underlying androgenetic alopecia, revealing how hormonal, oxidative, inflammatory, and lipid dysregulation suppress hair growth pathways and suggesting new therapeutic targets such as DP2 antagonists and microbiome modulators.

This study found that domestic temporary hair dyes may pose a health risk due to their cytotoxic effects on human red blood cells and NIH/3T3 cell lines.

These guidelines recommend testing thyroid function in patients with obesity due to common hypothyroidism, and highlight that weight loss is crucial for addressing hormonal imbalances, with only modest weight loss benefits from treating endocrine disorders.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This review covers the neuroendocrine aspects of polycystic ovary syndrome, focusing on hormones and neurotransmitters like GnRH and kisspeptin, but does not report new clinical findings.

This review discusses the structure and function of the testes in male reproduction and development, noting the complex hormonal regulation within the hypothalamic-pituitary-gonadal axis but reports no new clinical results.

This review discusses the role of microglia in mediating prenatal androgen effects on the female brain, potentially contributing to PCOS development and neuroendocrine dysfunctions, but reports no new results.

This chapter reviews pharmacodynamic evaluations in endocrine disorders focusing on oral antidiabetics, insulin analogues, and hormone interactions, but reports no new results.

This study found that neuroactive steroids like DHEA and pregnenolone influence cocaine-induced appetence in mice through their interaction with the ς₁ receptor, suggesting a role in individual vulnerability to addiction.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

Sex hormones affect reproduction, sexual development, and oral health, and it's important for dental practitioners to understand their effects and interactions.

In this study, repeated finasteride administration was associated with decreased social interaction and cognitive deficits in male rats, potentially linked to changes in cholinergic system activity.

This review examines the role of nuclear hormone receptors in skin wound repair processes and reports no new clinical results, highlighting the importance of their interaction with skin cells for effective healing.

In this study, researchers found that 24.7% of female medical students were diagnosed with PCOS, significantly affecting their academic success and social interactions due to symptoms like BMI abnormalities and acne, suggesting that educators should enhance support and awareness to address these challenges.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study observed that testosterone concentrations in hair segments show some stability over time, but are influenced by factors like sebum integration, hair washing frequency, and individual hair growth rates.

This review examines sulforaphane's interactions with hormone-mediated health conditions, focusing on gender-specific health issues, but reports no new original research findings.

This study used bioinformatics to explore molecular differences in testicular and ovarian responses to SARS-CoV-2, identifying genes that could be associated with sex differences in infection outcomes.

This research suggests that autism's genetic links are partially related to factors influencing physiological sex differences, with rare variants interacting with placental sex differences and common variants affecting steroid-related traits.
