The impact of adipose tissue-derived factors on the hypothalamic-pituitary-gonadal (HPG) axis.
Adipose tissue produces factors, including adipokines, cytokines and chemokines which, when released, systemically exert endocrine effects on multiple tissues thereby affecting their physiology. Adipokines also affect the hypothalamic-pituitary-gonadal (HPG) axis both centrally, at the hypothalamic-pituitary level, and peripherally acting on the gonads themselves. Among the adipokines, leptin, ...
متن کاملThe fetal and neonatal hypothalamic-pituitary-adrenal axis.
The hypothalamus, pituitary, and adrenal glands are dynamic endocrine organs during fetal development. The adrenal glands, in particular, exhibit remarkable transformation in size, morphology, and function during the prenatal and neonatal periods. 3 It is now recognised that normal development of the hypothalamic–pituitary–adrenal (HPA) axis is essential for: (1) the regulation of intrauterine ...
متن کاملWidespread patterns of sexually dimorphic gene expression in an avian hypothalamic–pituitary–gonadal (HPG) axis
The hypothalamic-pituitary-gonadal (HPG) axis is a key biological system required for reproduction and associated sexual behaviors to occur. In the avian reproductive model of the rock dove (Columba livia), we characterized the transcript community of each tissue of the HPG axis in both sexes, thereby significantly expanding our mechanistic insight into HPG activity. We report greater sex-biase...
متن کاملThe Role of Central Nervous System and Hypothalamic-Pituitary-Gonadal (HPG) Axis Changes in the Occurrence of Polycystic Ovary Syndrome: A Narrative Review Article
Background and Objectives: Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder, affecting at least 10% of women in reproductive age. It is associated with hyperandrogenism, obesity, menstrual iregularity and infertility. There are several hypotheses regarding the metabolic, genetic, epigenetic, and environmental causes of the disease. Although the main cause of the dise...
متن کاملThe effect of immobilization stress on the HPG axis (hypothalamic - pituitary - gonad) hormones and the number of spermatogonia
Background & Objective: Stress has different effects on the living organisms. In this study the effect of immobilization stress the HPG (hypothalamic - pituitary - gonad axis) hormones secretion and the number of spermatogonia was studied in adult male rats Materials & Methods: 30 male rats were divided into 3 groups. The Control group: who were not exposed to any kind of stress, and two exper...
