The Iberian lynx (Lynx pardinus) is the most critically endangered felid. A high reproductive success within the Iberian Lynx Conservation Breeding Program is crucial to maintaining the goal of reintroducing captive born offspring to the wild and thus increasing the population. Lynx follow a unique reproductive strategy with a monoestrous cycle and persisting CLs over many years. These persistent CLs constantly produce progesterone (on average 5 ng/mL) and are hypothesized to hinder a polyestrous cyclicity in lynx. The aim of this study was to evaluate whether artificial luteolysis can be achieved with common luteolytic drugs and if luteolysis would induce a second estrus naturally. We obser..View full abstract
