Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

open access: yesAndrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.
