Update on pubertal development
Current Opinion in Obstetrics and Gynecology, 1999This review provides updated information relating to the timing of pubertal onset from a large study of girls seen in pediatric practices. In addition, new studies investigating the relationship of the hormone leptin to the onset of puberty are discussed, as well as new information on the neuroendocrine control of pubertal regulation.

Disorders of pubertal development
Best Practice & Research Clinical Obstetrics & Gynaecology, 2003Puberty is the period of life during which reproductive capability is acquired. It is characterized clinically by the acquisition of secondary sexual characteristics associated with a growth spurt, and on average takes 3-4 years. Early maturation is defined as the development of sexual characteristics before the age of 8 years in girls and 9 years in ...

Leptin and Pubertal Development
Seminars in Reproductive Medicine, 2002Sexual development after birth in rodents, nonhuman primates, and humans is driven by the gonadotropin-releasing hormone (GnRH) pulse generator. During the neonatal period in primates, pulsatile GnRH discharge from the medial basal hypothalamus drives an active period of pituitary gonadotropin and gonadal hormone secretion.

Challenges in Pubertal Development
Journal of Pediatric and Adolescent Gynecology, 2002Today we are going to discuss some of the clinical challenges in pubertal development. Puberty is a time of tremendous physical and emotional change for the adolescent. When all goes well and it follows the expected course it is often difficult not only for the teen but also for her parents.

Inhibin B in Pubertal Development and Pubertal Disorders
Seminars in Reproductive Medicine, 2004The inhibin B pubertal surge is a prominent signal of gonadal maturation in females as well as in males. In boys, it denotes the final functional maturation of Sertoli cells, which is accompanied by a progressive suppression of antimüllerian hormone production.

Acta Paediatrica, 1976
The pubertal development of 212 randomly selected Swedish urban children has been investigated as part of a prospective longitudinal study of growth and development. The timing and pattern of pubertal changes were in agreement with the findings in other contemporary studies.

Racial Disparities in Pubertal Development
Seminars in Reproductive Medicine, 2013The question of whether or not children, particularly girls, are entering puberty earlier than they did in the past has been a concern in both the medical community and the general population. A secular trend analysis of the current data on pubertal timing in boys and girls is limited by variations in the study design, the population assessed, and the ...

Update on female pubertal development
Current Opinion in Obstetrics and Gynecology, 2002To elucidate recent findings regarding female puberty. The successful completion of puberty is a prerequisite for reproduction. Many later disorders of fertility and metabolism may develop during puberty. New more sensitive and specific assays provided us with possibilities for a better understanding of the process of puberty, and the discovery of new ...

Pubertal development in male hypopituitarism
European Journal of Pediatrics, 1986The spontaneous or therapeutically induced pubertal development of 65 male patients with idiopathic hypopituitarism was analysed. Spontaneous puberty occurred in 82% of the patients with prepubertal isolated growth hormone deficiency and in 32.5% of those with impairment in the secretion of more than one pituitary hormone.

Pubertal Development and Menarche
Annals of the New York Academy of Sciences, 2008Puberty is the developmental process that culminates in reproductive capability and is the result of a complex series of molecular and physiological events. The release of gonadotropin‐releasing hormone from specialized neurons of the hypothalamus begins the hormonal cascade that causes gonadal activation and the physical changes of puberty.
