The hypothalamic-pituitary-testicular axis: studies on delayed puberty and infertility
… in 16 patients (mean age 16.3 ± 2.7 years) with delayed sexual development while their clinical progress was followed for a mean duration of 22.4 ± 8.5 months. Changes in testis and genital size were confirmed to be the two physical markers which correlated best with the hormonal patterns. The …

IDENTIFICATION OF MECHANISMS OF DELAYED PUBERTY ON BONE STRENGTH DEFICITS DURING DEVELOPMENT
… 2002). Bone mass doubles during the onset of puberty and young adulthood (Katzman et al., 1991) with more than 90% of peak bone mass being accrued at the end of second decade of life (Schneider & Wade, 2000). The rate of periosteal expansion is elevated during the pubertal period (Specker et …

NOVEL INSIGHTS INTO GENETIC AND ENVIRONMENTAL DETERMINANTS SHAPING GNRH NEURON BIOLOGY AND RELATED REPRODUCTIVE DISORDERS
… congenital disorder characterized by absent or delayed puberty and infertility. While once considered a monogenic condition, IGD is now recognized as genetically heterogeneous, with oligogenic inheritance frequently observed. Although over 44 genes have been implicated in IGD, only about 50% of …

Intrinsic Neuronal Plasticity of Kiss1 Neurons in Mice around Puberty
Puberty is a critical stage in mammalian development, characterized by rapid somatic growth, sexual maturation, and the final maturation of the central nervous system. The timing of puberty is crucial, as initiating it either too early or too late can lead to adverse outcomes. Precocious puberty …

Management and nutrition of the replacement gilt.
… four experiments; one, to identify whether the puberty stimulation and mating strategies developed for genotypes of 20 to 30 years ago are suitable for today’s heavier yet leaner genotypes; and two, to better understand the influence of pre-pubertal growth rate and metabolic status on …

Investigating mechanisms of ovotoxicity of Perfluorooctanoic acid and Zearalenone exposure and the influence of altered metabolic status on ovarian function
… In females, exposure to PFOA has been linked to delayed puberty, early menopause, endocrine disruption, reduced fertility, and premature ovarian insufficiency. Mechanisms of PFOA-induced ovarian toxicity including alterations to the levels of E2 and P4, changes to the ovarian abundance of …
