Summary: This study aimed to describe the timing and patterns of pubertal maturation of girls in rural Bangladesh. The results showed that girls in this population progressed through puberty following a well-documented sequence of sexual maturation stages, with the age at each pubertal milestone being somewhat later compared to other studies.

Summary: This study from the LEGACY Girls Study in North America found associations between childhood viral infections (CMV, EBV, HSV1, HSV2) and pubertal timing, with CMV infection without coinfection being associated with earlier breast development and CMV infection without coinfection or HSV1 and/or HSV2 infection being associated with later pubic hair development. The findings suggest a potential role of childhood infections in altering pubertal timing.

Summary: This study found that higher weight-for-age z score and rapid weight gain during infancy, particularly from birth to 3 months of age, were associated with an increased likelihood of puberty onset in girls.

Summary: This study investigated the association between congenital heart defects (CHD) and pubertal timing using longitudinally collected data on pubertal milestones. The results showed no association between CHD and pubertal timing.

Summary: Rodents are omnivorous animals that primarily feed on plants, including various species such as rabbits, hamsters, and mice. They usually live on the ground, but there are also species that live in trees. Their characteristics include sharp incisors and lateral movement of the jaw.

Summary: Studies have shown that prenatal monoethyl phthalate (MEP) concentrations may be associated with slightly earlier timing of puberty, including age at menarche. However, findings on peri-pubertal phthalate exposures and pubertal outcomes were inconsistent, as were studies on prenatal and peri-pubertal phenol exposures. Limited research has been conducted on parabens in relation to girls' pubertal development.

Summary: The study revealed that early maternal age at menarche was associated with earlier pubertal timing in both girls and boys in Chongqing, particularly affecting girls' age at menarche and boys' first ejaculation. Children's body mass index and socioeconomic conditions also played a significant role in influencing pubertal timing.

Summary: The accuracy of uterine artery pulsatility index (PI) in diagnosing puberty in girls was assessed in this scoping review. Ten studies, involving 1385 girls aged 1.2-18 years, were included. The studies showed significant differences in Doppler signal pattern and PI according to pubertal stage, with PI cutoff points ranging from 2.5 to 4.6, sensitivity of 77%-94%, specificity of 85%-100%, and accuracy of 79%-98%. Doppler assessment of the uterine arteries with PI calculation is a useful noninvasive tool in the diagnosis of pubertal onset in girls.

Summary: The study found associations between father absence in pregnancy and during childhood with earlier pubertal development in girls, and father absence from late childhood with earlier pubertal development in boys. The paternal investment theory, psychosocial acceleration theory, and energetics theory did not explain these associations.

Summary: This study examined the associations of prenatal and childhood exposure to per- and polyfluoroalkyl substances (PFAS) with pubertal development and reproductive hormones. The results showed that adolescent PFAS concentrations were associated with later pubic hair growth, breast maturation, and age at menarche in females, but there was no pattern for prenatal or other postnatal concentrations. No associations were observed between PFAS concentrations and pubic hair growth or reproductive hormones in males.

Summary: This study examines the relationship between growing up in father-absent households and pubertal timing in Korean adolescents. While no association was found between father absence and earlier onset of menarche in girls, boys in father-absent households reported their first nocturnal ejaculation at a younger age on average, with the difference becoming evident before age 14.

Summary: This study found that polycyclic aromatic hydrocarbons (PAHs) can affect the timing of pubertal development in overweight girls, particularly the development of breast and pubic hair. This is an important risk factor for breast cancer.

Summary: The association between mammographic density and breast cancer risk has been well-established, with puberty identified as a critical time for breast development and adult mammographic density. The molecular and cellular mechanisms underlying the development of high mammographic density are still not fully understood.

Summary: Over the past decade, pubertal development has been occurring earlier in Chinese children. The age for breast development in girls is 9.65 years and for testicular volume ≥ 4 mL in boys is 10.65 years. Obesity and overweight are associated with a higher risk for early puberty onset.
