[QUOTE="Nelson Vergel, post: 181219, member: 3"] [B]Age‐dependent changes in the reproductive axis responsiveness to kisspeptin‐10 administration in healthy men[/B] Andrologia, May 2019, Vol.51(4), pp.n/a-n/a The present study was designed to assess the responsiveness of hypothalamic–pituitary–gonadal axis to kisspeptin administration with increasing age in men.
