A dominant X-linked QTL regulating pubertal timing in mice found by whole genome scanning and modified interval-specific congenic strain analysis. [PDF]

PLoS ONE, 2008
BackgroundPubertal timing in mammals is triggered by reactivation of the hypothalamic-pituitary-gonadal (HPG) axis and modulated by both genetic and environmental factors. Strain-dependent differences in vaginal opening among inbred mouse strains suggest

Pubertal Onset in Boys and Girls Is Influenced by Pubertal Timing of Both Parents [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2016
Context: Epidemiological evidence on maternal and paternal heritability of the wide normal variation within pubertal timing is sparse. Objective: We aimed to estimate the impact of parental pubertal timing on the onset of puberty in boys and girls.

Sex- and brain region-specific patterns of gene expression associated with socially-mediated puberty in a eusocial mammal. [PDF]

PLoS ONE, 2018
The social environment can alter pubertal timing through neuroendocrine mechanisms that are not fully understood; it is thought that stress hormones (e.g., glucocorticoids or corticotropin-releasing hormone) influence the hypothalamic-pituitary-gonadal ...

Pubertal timing and breast density in young women: a prospective cohort study. [PDF]

, 2019
BACKGROUND:Earlier age at onset of pubertal events and longer intervals between them (tempo) have been associated with increased breast cancer risk. It is unknown whether the timing and tempo of puberty are associated with adult breast density, which ...

Early Life Adversity and Pubertal Timing: Implications for Cardiometabolic Health.

Journal of Pediatric Psychology, 2020
OBJECTIVE  To identify early life adversity (ELA) risk factors for earlier pubertal timing, itself a risk factor for poor cardiometabolic health, and to determine whether such ELA-related risk may be mediated by pre-pubertal body mass index (BMI ...

Pubertal development timing in urban Chinese boys [PDF]

International Journal of Andrology, 2011
We describe current pubertal development in healthy urban Chinese boys. A cross-sectional study of the pubertal development of 18,807 urban Chinese boys aged from 3.50 to 18.49years was conducted between 2003 and 2005. Testicular volume was evaluated with a Prader orchidometer. Pubic hair development was assessed according to the Tanner method. Data on

Examining the relationship between pubertal stage, adolescent health behaviours and stress [PDF]

, 2003
Background. This paper examines the associations between puberty and three important health behavlours (smoking, food intake and exercise) and explores whether these associations are mediated by puberty's relationship to stress and psychological ...

Prenatal nitrate exposure from diet and drinking water and timing of puberty in sons and daughters: A nationwide cohort study

Environment International, 2022
Background: In Western countries, age at pubertal development has declined during the last century in girls, and probably also in boys. No studies have investigated whether nitrate, a widespread environmental exposure with teratogenic and hormone ...
