Background: Puberty is a transition period between childhood and adulthood influenced by various complex factors. Nutrition is one of the most important factors affecting pubertal development. Overweight or obese children are more likely to enter puberty earlier. Severe primary or secondary malnutrition can also delay the onset and progression of puberty. This study aims to determine the relationship between nutritional status and pubertal disorders in Denpasar city orphanage children. Methods: This study was conducted using an analytic research design with a cross-sectional design to determin

The human is the product of the specific interaction of natural and social factors. Periods of age were divided by specialists differently; Demeter, A.

The Introduction of vasectomised rams to ewe lambs may hasten the occurrence of puberty and, if the introduction of fertile rams is not advanced, mating may occur later in the breeding season with possible advantages to fertility.

Abstract Puberty is a crucial period of transition to adulthood, marked by an increased activation of gonadotropin-releasing hormone (GnRH) neurons that drives increased pulsatile secretion of pituitary luteinizing hormone (LH). The mechanisms governing GnRH neuron activation at puberty remain unclear but are likely due to enhanced signaling from upstream neuron populations, including kisspeptin neurons. Kisspeptin (encoded by Kiss1) directly stimulates GnRH neurons to drive GnRH release and downstream LH secretion. Humans and animals with Kiss1 mutations fail to reach puberty, demonstrating k

This overview explores the complex relationship between environmental factors, particularly obesity, and the timing of puberty, with a focus on how hormonal and genetic interactions are influenced by external conditions. Puberty (gonadarche) is characterised by the activation of the hypothalamic–pituitary–gonadal (HPG) axis. The onset and progression of puberty vary significantly among individuals, primarily due to genetic factors, with key genes like kisspeptin 1 (KISS1) and makorin ring finger protein 3 (MKRN3) playing a crucial role.

To attain sexual competence, all mammalian species go through puberty, a maturational period during which body growth and development of secondary sexual characteristics occur. Puberty begins when the diurnal pulsatile gonadotropin-releasing hormone (GnRH) release from the hypothalamus increases for a prolonged period of time, driving the adenohypophysis to increase the pulsatile release of luteinizing hormone with diurnal periodicity. Increased pubertal GnRH secretion does not appear to be driven by inherent changes in GnRH neuronal activity; rather, it is induced by changes in transsynaptic

Abstract: Puberty is an important stage of human life. Several physiological alterations accompanying the teenage years manifest themselves in often complex and curious means to which females show different reactions. Even though this stage of a female's life is normal, it is often associated with some degree of suffering and embarrassment, it is mainly due to a sense of hesitation. The main event of puberty is the onset of the menstrual cycle; menstruation is a normal physiological process that has been distorted and damaged with negative connotations.

Abstract An increase in pulsatile release of LHRH is essential for the onset of puberty. However, the mechanism controlling the pubertal increase in LHRH release is still unclear. In primates the LHRH neurosecretory system is already active during the neonatal period but subsequently enters a dormant state in the juvenile/prepubertal period. Neither gonadal steroid hormones nor the absence of facilitatory neuronal inputs to LHRH neurons is responsible for the low levels of LHRH release before the onset of puberty in primates.

Genetic mechanisms from single gene mutations to single nucleotide polymorphism associated with delayed puberty are being identified.

Abstract To follow and correlate gonadotropin and sex steroid changes throughout puberty, 24-h profiles of LH, FSH, testosterone, and estradiol were taken on several occasions for between 2–9.5 yr in 12 healthy boys, aged 8.7–18.2 yr. Serum concentrations of LH and FSH were measured every 20 min, whereas testosterone and estradiol were measured every 2–4 h during the 24-h period. The prepubertal boys (Tanner stage 1) were subdivided into two groups: Pre 1, with a testicular volume of 1–2 mL, and Pre 2, with a testicular volume of 3 mL. Pubertal stages were classified, according to testicular v

AbstractObjectivesGrowth references of today traditionally describe growth in relation to chronological age. Despite the broad variation in age of pubertal maturation, references related to biological age are lacking. To fill this knowledge gap, we aimed to develop a new type of pubertal height reference for improved growth evaluation during puberty, considering individual variation in pubertal timing.MethodsLongitudinal length/height measures were obtained from birth to adult height in 1,572 healthy Swedish children (763 girls) born at term ∼1990 to nonsmoking mothers and Nordic parents, a su

The low level of somatic and reproductive health before pregnancy causes a high frequency of complicated births, leading to a deterioration in the development of subsequent generations. The

Puberty is a very important stage for all teenagers, both boys and girls. The puberty period will change from childhood to adulthood. These changes include hormonal changes, physical changes, psychological and social changes. Puberty is the process of changing physical and sexual immaturity towards physical and sexual maturity. The physical and sexual maturity phase can enable a teenager's reproductive organs to function for reproduction.

Introduction: Puberty is a juvenile developmental period accompanied by intensive growth and acquisition of reproductive ability. The onset of puberty is influenced by many factors: genetics, neuropeptides and glycoproteins, gonadotropins, sex hormones and the child's nutrition status. Premature puberty is defined as the appearance of secondary sexual characteristics in girls before the age of 8, and in boys before the age of 9. The aim of this paper is to analyze the published results on the importance and influence of factors such as birth weight, current weight and BMI on the development of

Abstract In primates, despite the fact that GnRH neurons are mature at birth, a gonadal steroid independent central inhibition restrains the initiation of puberty. The neural substrates responsible for this central inhibition, however, are unclear. In this study, we tested the hypothesis that neuroestradiol release in the hypothalamus decreases prior to the pubertal increase in GnRH release. We found that in female monkeys at the prepubertal stage, when GnRH release was low, estradiol (E2) levels in the stalk-median eminence of the hypothalamus were higher than those in older, early pubertal f
