This article reviews puberty's onset, development, and the factors affecting it, including nutrition, obesity, and gender dysphoria, and reports no new clinical results.

This study found that higher prenatal and early childhood lead exposure may be associated with delayed pubertal development in girls, but not in boys, in Mexico City.

This study suggests a possible link between late puberty onset and decreased prostate cancer risk, while over-the-counter ibuprofen use was associated with increased risk.

This study observed that higher childhood fluoride exposure was associated with delayed pubertal development in Mexican boys aged 10-17, with no significant effects found in girls.

This study observed that higher PFAS concentrations during adolescence were linked to later pubertal development and lower estradiol levels in females, but not in males, potentially due to PFAS excretion with menstrual fluid.

This study found that boys in Mexico City with selenium intake below the recommended dietary allowance had lower odds of progressing to advanced stages of pubertal development, while no association was observed in girls.

This study found that early adolescent girls who perceive themselves as undergoing pubertal changes report more intense and variable moods, with hormone activity and perceived pubertal status independently predicting mood fluctuations.

This study reports that prenatal and prepubertal exposure to organochlorine compounds and perfluoroalkyl substances may affect pubertal development at age 12, with observed changes in development patterns in both girls and boys, highlighting the need for further research.

This article reviews the physiological changes underlying normal pubertal milestones and emphasizes the importance of understanding these changes to assess pubertal abnormalities, without reporting new clinical findings.

This article reviews various aspects of puberty, particularly focusing on the staging of sexual maturity and the factors influencing pubertal onset, but reports no new empirical results.

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 case report details the investigation and management of a 3-year-old girl with precocious pseudopuberty due to a Sertoli-Leydig cell tumor, highlighting the importance of early recognition and accurate diagnosis for effective treatment and prognosis.

This study reported that higher weight-for-age z scores and rapid weight gain during infancy, especially from birth to 3 months, were linked to an increased likelihood of puberty onset in girls.

This study found that prenatal exposure to fluoride and lead, as well as maternal micronutrient intake, may influence sexual maturation in adolescents in a sex-specific manner.

This study observed that girls in rural Bangladesh experienced pubertal milestones later than in some other populations, but progressed through puberty at a similar pace from breast development to menarche.

In this study, daughters of mothers who consumed 8 or more cups of coffee per day during pregnancy experienced pubertal development about 2 months earlier than daughters of mothers who did not consume coffee, whereas no such differences were observed among sons.

This study observed that higher childhood levels of DHEAS were associated with more advanced pubertal development and correlated with changes in DNA methylation near puberty-related genes in both boys and girls, potentially explaining the hormone's influence on puberty.

This study found that adolescent girls with PCOS experienced earlier thelarche and menarche compared to controls, and the authors suggest these patterns may relate to hyperandrogenism and increased body mass index.

In this retrospective study, cyproterone acetate treatment in late-pubertal trans-girls was found to be generally safe and led to mild feminizing effects, with more rapid feminization occurring when combined with estrogens.

This study observed that androgen levels rise with pubic hair development in Tanner stages, differing by sex and age, with DHEA showing a significant prepubertal increase especially in precocious adrenarche.

This case report described a 9-year-old girl initially suspected to have complete androgen insensitivity syndrome, whose laboratory tests later suggested an alternative diagnosis involving atypical steroid metabolism patterns and hormonal responses.

This review discusses the potential impact of endocrine-disrupting chemicals and body size on pubertal onset and progression, highlighting critical gaps and priorities for future research without presenting new clinical results.

This study found that androgenetic alopecia is the leading cause of hair loss in adolescents and may indicate endocrine disorders, emphasizing the need for accurate diagnosis.

This review discusses factors influencing the earlier onset of puberty, such as obesity and exposure to endocrine-disrupting chemicals, and emphasizes the need for further research and public health policy development.

This review discusses the challenges in optimizing glucocorticoid treatment for classic 21-hydroxylase deficiency, emphasizing individualized care and the need for comprehensive management, but presents no new findings.

In this study conducted among healthy Iranian girls in Isfahan province, researchers found that the median onset age for menstruation was 12.05 years, breast development began at 9.89 years, and pubic hair development started at 10.14 years, with earlier puberty onset potentially indicating precocious puberty.

This correspondence highlights a study on early pubertal development in young girls, noting that early pubic hair and breast development in African-American girls is likely due to increased androgen production, not estrogen or exogenous causes.

This study reported that treatment with cyproterone acetate alone and then with incremental estrogen doses induced mild feminizing effects in late-pubertal trans-girls, with further feminization observed after adding estrogen.

This retrospective study found that cyproterone acetate, both alone and with estrogens, was safe, well tolerated, and induced modest feminizing effects in late-pubertal transgender female adolescents.

Pubertal acne is linked to hormonal changes, affects quality of life, and is treated similarly to adult acne.
