Summary: Sex hormones play a crucial role in gender-related differences and influence growth and development during puberty. They also have a significant impact on immune cell functions, with a distinct immune response between males and females. Clinical and animal studies have shown that androgens, estrogens, and progestogens are involved in gender-specific immune responses, affecting susceptibility to infectious diseases and autoimmune disorders. Androgens and progestogens mainly promote immunosuppressive or immunomodulatory effects, while estrogens enhance humoral immunity in both genders. This study reviews the available evidence on the physiological effects of sex hormones on human immune cell function and the underlying biological mechanisms, particularly focusing on gender differences triggered by different levels of androgens.

Summary: This article reviews important findings about sex steroid metabolism in the mouse olfactory system and suggests potential areas for further research. The expression, distribution, and biological activity of steroidogenic enzymes, sex steroid receptors, and relevant proteins are summarized, along with their potential impact on early olfactory processing.

Summary: Excessive fat accumulation in the body leads to overweight and obesity, with white adipose tissue (WAT) and brown adipose tissue (BAT) having opposing functions. Sex differences in BAT activity may play a significant role, highlighting the importance of understanding the underlying mechanisms contributing to these differences. Studies also suggest a potential crosstalk between sex hormones and the hypothalamic-pituitary-adrenal axis in metabolism, further emphasizing the need to explore sex differences in BAT activity.

Summary: Traumatic brain injury (TBI) is a serious health concern that can lead to death. This study investigates the effect of TBI on local neurosteroid levels near the injury site and in plasma. The results show that TBI alters the levels of estrogen, androgen, and progesterone, which may contribute to neuroprotection.

Summary: For a long time, it was believed that sex steroids activate reproductive behaviors through changes in DNA transcription, but in recent decades it has been discovered that the behavioral effects of steroids are too rapid to be mediated through this pathway, but rather through membrane-initiated events. This has led to a shift in understanding of how steroids influence behavior. The review summarizes the important role of membrane-associated receptors such as estrogen, androgen, and progestagen receptors in controlling reproductive behaviors, as well as specific behavioral systems where membrane-initiated events have been established to contribute to behavior control.

Summary: This study evaluated the receptor agonist activities of estrogen, androgen, and glucocorticoid in river water samples from Chennai and Bangalore (India), Jakarta (Indonesia), and Hanoi (Vietnam) using CALUX assays. The results showed that the major contributors to the agonist activities were estrogens and androgens, with the samples from India having higher activities.

Summary: This article discusses the impact of hormonal changes during the menstrual cycle on women's exercise physiology, specifically focusing on energy substrate metabolism and macronutrient utilization. It aims to provide a perspective on the limitations of previous research studies and suggests approaches for future studies to provide evidence supporting the idea that menstrual cycle hormonal changes do affect energy metabolism in women during exercise.

Summary: Analysis of hormone profiles in humpback whale baleen revealed differences in cortisol, corticosterone, testosterone, and estradiol levels between pregnant and non-pregnant periods. Understanding these hormonal changes can provide valuable insights into the reproductive physiology of whales over time, aiding in population growth assessments and conservation efforts.

Summary: The study found no significant associations between long-term exposure to air pollutants and pubertal development based on sex hormone concentrations among 10-year-old children. More longitudinal studies are needed to further assess this association due to the limited number of current studies on this topic.

Summary: Sex steroid hormones have significant effects on the thymus, causing thymic atrophy. Thymic epithelial cells (TEC), which are highly responsive to sex steroids, play a crucial role. Endogenous steroids have remarkable programming effects on the synthesis of T cell receptor (TCR) repertoire through TEC.

Summary: This study confirmed that the human vagina is an androgen-target organ with the ability to synthesize androgens, thus providing support for the use of androgens for local symptoms of genitourinary syndrome in menopause.

Summary: Our study found that E-DII was positively associated with androgens and estrogens in postmenopausal women, with some indicators showing non-linear associations, particularly among women who experienced natural menopause. Further research is needed to explore the underlying mechanisms.

Summary: This study found that cortisol may be a useful predictor of perinatal loss, while cortisol and androstenedione were useful for distinguishing failed to thrive pregnancies. Similarly, both testosterone and estradiol levels during early loss and false pregnancy differed from normal pregnancies.

Summary: Insulin-mediated substrate use is impaired in women with PCOS regardless of phenotype, with a greater impact in individuals with the classic phenotype. Free testosterone independently contributes to abnormalities in insulin action in glucose and lipid metabolism.
