WebKisspeptin neurons are also important in this phenomenon showing increased expression and terminal apposition to GnRH neurons during the breeding season. Reduced kisspeptin expression during the non-breeding season can be overcome by administration of kisspeptin, which causes ovulation in seasonally acyclic females.
