Puberty is the maturation stage a person goes through when they develop secondary sexual characteristics. Usually, puberty occurs between the ages of 8 and 12 years in girls and between 9 and 14 years in boys.

Prenatal paracetamol exposure linked to smaller ovaries in daughters

Researchers in Denmark have found that girls whose mothers took paracetamol during pregnancy had smaller ovaries, fewer ovarian follicles (the structures that contain immature eggs), smaller uteruses and lower levels of reproductive hormones at three months old.

Study links thymus radiation to worse lung cancer outcomes

Until recently, the thymus was thought to be of little use beyond puberty, but new research has shown that radiation to the organ is associated with worse outcomes in patients being treated for non-small cell lung cancer (NSCLC).

Inherited Neandertal gene variant increases muscle mass in modern humans

Neandertals were generally more strongly built than most people living today. Their bones show signs of large muscles, and they had characteristic features such as prominent brow ridges and relatively short tooth roots.

Exposure to fungicides and insecticides alters onset of puberty in girls

The study, which tracked more than 500 Spanish girls between the ages of 7 and 10, links the presence of certain fungicides in urine to early menarche and that of the insecticide chlorpyrifos to delayed menarche, highlighting the impact of pesticides on pubertal development.

Experts recommend renaming PCOS to better reflect whole-body impacts

A condition affecting approximately 170 million adolescents and women worldwide has a new name – one that better reflects its complexity and far-reaching health impacts.

Biological markers reveal clinical vulnerability in abused children and adolescents

In children and adolescents who have experienced child abuse, the body appears to remain in a state of alert for too long, and this situation can affect several bodily systems, such as the neuroendocrine, immune and metabolic systems.

Phenolic compounds linked to precocious puberty or early breast development in girls

Research from the University of Granada, recently published in the European Journal of Pediatrics, has revealed that girls with higher levels of bisphenol A (a component of plastics and epoxy-phenolic resins) and benzophenones (ultraviolet filters) in their urine are more likely to experience precocious puberty or early breast development.

Gut microbes emerge as potential players in estrogen-driven cancers

A new review maps how the endocrine-microbiome axis expands the estrobolome concept, showing that gut microbes may alter estrogen recycling, produce hormone-like metabolites, and shape inflammation and tissue environments in hormone-driven cancers. Human evidence remains mostly associative, so the authors call for causal models, longitudinal multi-omics, multi-kingdom profiling, and sex-stratified studies before microbiome-guided cancer strategies enter routine care.

New guideline recommends tailored care for precocious puberty

Some subgroups of children with precocious puberty-such as older girls with slowly progressing puberty-may not need the same level of testing or treatment, according to a new Endocrine Society Clinical Practice Guideline released today.

Study uncovers genetic trade-off between youth and longevity

A new study identifies vgll3 as a key gene that promotes rapid growth and early reproduction while increasing the risk of aging and cancer later in life.

AI model tracks child maturity patterns through routine ECG data

A new study from Wake Forest University School of Medicine suggests a routine heart test – an electrocardiogram (ECG) – may offer researchers a new way to measure biological development in children and adolescents.

Prenatal forever chemical exposure may affect puberty timing in children

An EHU-University of the Basque Country and Biogipuzkoa Health Research Institute study has linked certain chemicals measured during the first trimester of pregnancy to the subsequent onset of puberty in the children.

Why blood pressure rises faster in women after midlife

This review examines how sex-specific blood pressure trajectories are shaped by genetics, hormones, metabolic risk factors, lifestyle exposures, environmental stressors, and medical treatments. It highlights that women generally have lower blood pressure earlier in life but may experience steeper increases with aging, especially around and after menopause, with exogenous stressors appearing to have a greater impact in women than in men.

Higher ferritin threshold could detect childhood iron deficiency much earlier

Many cases of iron deficiency in school-aged children could be diagnosed earlier, according to a new study published in Blood Red Cells & Iron, a journal of the American Society of Hematology (ASH).

Selective eating in autism linked to inflammatory gut bacteria

Eating habits shape gut bacteria in children with autism, with potential dietary interventions offering hope for improving gut health and inflammation.

Infant exposure to environmental chemicals linked to lower bone density

Infants exposed to certain environmental chemicals, including breast milk and everyday products such as personal care items, are more likely to have lower bone density in the first year of their lives, according to research presented at the 28th European Congress of Endocrinology in Prague.

People judge GLP-1 users more harshly than dieters

Stigma surrounding GLP-1 weight loss treatments reveals societal biases, impacting individuals' mental health and the effectiveness of obesity interventions.

Blood protein levels shift significantly from childhood through early adulthood

Blood protein levels change markedly already during childhood and adolescence, and differences between girls and boys become increasingly pronounced with age.

Researchers debunk the existence of the childhood "adiposity rebound" phenomenon

In new research to be presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) and published in The Journal of Nutrition, a 42-year old theory as to why children's body mass index (BMI) decreases post-infancy before then rising continuously from age six years –'the adiposity rebound' is refuted using new analyses – rather than decreasing body fat, the real reason is proposed as increasing muscle mass.
