Normal puberty is a time of life and a process of development that results in full adult maturity of growth, sexual development, and psychosocial achievement. Delayed puberty describes the clinical condition in which the pubertal events start late (usually > +2.5 SD later than the mean) or are attenuated in progression. The differential diagnosis includes syndromes of low gonadotropin production, usually constitutional delay of growth and maturation associated with chronic disease, but also an array of gene-mediated disorders, and syndromes of primary gonadal dysfunction with hypergonadotropic hypogonadism, including Turner and Klinefelter syndromes, and a group of acquired and genetic abnormalities. Diagnostic assessment and varied therapeutic modalities are discussed. The issues of androgen or estrogen therapy are important to assess, and growth hormone treatment remains a difficult dilemma.

Thematic Review of Endocrine Disruptors and Their Role in Shaping Pubertal Timing.
Children (Basel)
January 2025
Department of Pediatrics, Division of Pediatric Endocrinology, Demiroğlu Bilim University, 34394 Istanbul, Türkiye.
This review examines the inconsistent effects of endocrine-disrupting chemicals (EDCs) and pollutants on pubertal timing, emphasizing the methodological challenges contributing to variability in findings. Data from nine key studies reveal that chemicals such as BPA, phthalates, and PFAS impact pubertal onset differently based on exposure timing, dosage, and sex. For instance, BPA is linked to earlier puberty in girls but delayed onset in boys, while other EDCs show mixed effects across populations.

Background: Autoimmune hepatitis is a chronic liver disease marked by immune-mediated inflammation, necrosis, and the potential to progress to cirrhosis if not treated. This case report presents a rare and atypical presentation of autoimmune hepatitis in a Nigerian adolescent girl, highlighting diagnostic challenges in resource-limited settings. The case is unique owing to the absence of jaundice, a common symptom of liver dysfunction, and features such as delayed menarche and bilateral leg swelling.

Undernutrition has increased worldwide in recent years and it is known that environmental factors to which individuals are exposed in early life can result in metabolic and reproductive changes that remain in adult life. In this context, the litter size expansion is a classic model used to induce undernutrition early in development. Thus, this study aimed to evaluate the effects of neonatal undernutrition induced by the litter size expansion on metabolic and reproductive parameters of female rats.

Background: Proper planning of reproductive health needs for HIV-infected adolescents requires a clear understanding of the effects of HIV infection on adolescents' pubertal development.
Objective: To assess the effects of HIV infection on the hypothalamic-pituitary-ovarian (HPO) axis, ovarian reserve and pubertal development in adolescent girls at a tertiary hospital in Zimbabwe.
Methods: This was a cross-sectional survey of HIV-infected adolescent girls aged 10-19 years, with available CD4 + count results at a tertiary hospital in Zimbabwe.
HETEROKARYOTIC MONOZYGOTIC TURNER TWINS: AN INTERESTING PRESENTATION.
Acta Endocrinol (Buchar)
January 2025
Bursa Uludag University, School of Medicine, 1Department of Pediatric Endocrinology.
Turner syndrome is the most common sex chromosomal abnormality in about 1:2000-2500 live female births. While short stature and delayed puberty are the most common presentations of patients, atypical findings can also be seen. In this article, we present the Turner twins, who were diagnosed during inguinal hernia surgery when bilateral uterus and ovaries were found within the hernia sac.
