Growth Hormone Is Beneficial for Induction of Spermatogenesis in Adult Patients With Congenital Combined Pituitary Hormone Deficiency

Frontiers in Endocrinology, 2022
BackgroundGonadotropins are effective in inducing spermatogenesis in patients with congenital combined pituitary hormone deficiency (CCPHD). Data on recombinant human growth hormone(rhGH) adjuvant treatment to improve gonadotropin-induced spermatogenesis

Carbon Black Nanoparticles Selectively Alter Follicle-Stimulating Hormone Expression in vitro and in vivo in Female Mice

Frontiers in Neuroscience, 2021
Toxic effects of nanoparticles on female reproductive health have been documented but the underlying mechanisms still need to be clarified. Here, we investigated the effect of carbon black nanoparticles (CB NPs) on the pituitary gonadotropins ...

Expression of the gonadotropin receptors during follicular development

Reproductive Medicine and Biology, 2017
Gonadotropins induce follicular development that leads to ovulation and luteinization. In women, the level of gonadotropins, along with the expression of their receptors, changes dynamically throughout the menstrual cycle. This study aimed to clarify the

Disruption of Pituitary Gonadotrope Activity in Male Rats After Short- or Long-Term High-Fat Diets Is Not Associated With Pituitary Inflammation

Frontiers in Endocrinology, 2022
Overnutrition is associated with the activation of inflammatory pathways in metabolically linked organs and an early hypothalamic inflammation is now known to disrupt the central control of metabolic function. Because we demonstrated that fatty acids (FA)

The complementary effect of melatonin in accelerating ovulation and spawning of the Javaen barb Systomus rubripinnis (Valenciennes 1842) [PDF]

Brazilian Journal of Biology
The Javaen barb Systomus rubripinnis is an endemic fish not domesticated in Indonesia. This study aims to evaluate the effectiveness of gonadotropin and melatonin hormones in inducing ovulation of female Javaen barb. A total of 12 female fish (BW: 142.12

Activation of Gonadotropin-Releasing Hormone Neurons by Kisspeptin as a Neuroendocrine Switch for the Onset of Puberty

Journal of Neuroscience, 2005
We examined the role of kisspeptin and its receptor, the G-protein-coupled receptor GPR54, in governing the onset of puberty in the mouse. In the adult male and female mouse, kisspeptin (10–100 nm) evoked a remarkably potent, long-lasting depolarization ...

Chorionic gonadotropin [PDF]

Cancer, 1976
One of the most exciting and useful developments in modern oncology has been the recognition that certain biochemical tags can be used as cell markers in diagnosis, in monitoring the effects of anti-tumor therapy, and in follow-up to detect tumor recurrence. The measurement of chorionic gonadotropin (CG) in women with choriocarcinoma and/or gestational
