WebWe show that ARC kisspeptin neurons are upstream of GnRH neurons, and that GnRH neuron connectivity to ARC kisspeptin neurons does not depend on their spatial position in the brain. Furthermore, we demonstrate that the neural circuits between ARC kisspeptin and GnRH neurons are fully established and operative before birth.

WebAbstract. Kisspeptins, derived from the Kiss1 gene play a central role in activation of the hypothalamo-pituitary gonadal (HPG) axis via stimulation of GnRH neurons. Both Kiss1 and Kiss1R (receptor) mRNA levels are found to be low in pre-pubertal rats, but whether an increase in kisspeptin and/or its receptor is the primary component in the ... Web28 okt. 2024 · Kisspeptin-10 is most commonly used in post testosterone therapy as a part of PCT protocol, given that it stimulates GnRH, like HCG. It has been shown to be useful for treating a wide variety of fertility issues in men and women, as well as regulating the normal function of the hypothalamic pituitary gonadal axis.
