Frontiers in Endocrinology, 2018 Minipuberty consists of activation of the hypothalamic-pituitary-gonadal (HPG) axis during the neonatal period, resulting in high gonadotropin and sex steroid levels, and occurs mainly in the first 3–6 months of life in both sexes. The rise in the levels

Human Luteinizing Hormone and Chorionic Gonadotropin Display Biased Agonism at the LH and LH/CG Receptors [PDF]
Scientific Reports, 7(940) (2017), 2018 Human luteinizing hormone (LH) and chorionic gonadotropin (hCG) have been considered biologically equivalent because of their structural similarities and their binding to the same receptor; the LH/CGR. However, accumulating evidence suggest that LH/CGR differentially responds to the two hormones triggering differential intracellular signaling and ...

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]
, 2015 cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Pleotropism of gonadotropin action [PDF]
, 2020 Evidence exists that the gonadotropins LH and FSH can substitute to each other under certain circumstances, in addition to the fact that they can act together in granulosa cells. The aim of this study is to investigate how the two human gonadotropins influence each other in granulosa cells expressing both receptors, or by co-culturing cells expressing ...

Does Islamic Fasting Affect Gonadotropin around Female Ovulation? [PDF]
International Journal of Fertility and Sterility, 2010 Background The pattern of Islamic fasting differs from other forms of fasting, therefore its effect on health also differs. This research studies the effect of Islamic fasting on gonadotropin hormones around the time of the ovulatory cycle and ovulation.

Extragonadal LH/hCG action-Not yet time to rewrite textbooks [PDF]
, 2007 Gonadotropins are indispensable in both sexes in the regulation of gonadal sex steroid production and gametogenesis. In addition to their well-established classical actions, numerous recent publications have indicated the presence and function of ...

Regulation of reproduction via tight control of gonadotropin hormone levels. [PDF]
, 2018 Mammalian reproduction is controlled by the hypothalamic-pituitary-gonadal axis. GnRH from the hypothalamus regulates synthesis and secretion of gonadotropins, LH and FSH, which then control steroidogenesis and gametogenesis. In females, serum LH and FSH
