“…Despite that rabbits are the most widely studied induced ovulator and the first species to be identified as such more than 100 year ago, the principal stimulus responsible for triggering ovulation in rabbits is still unclear. Recently, OIF/NGF has been found in high concentration in rabbit seminal plasma (Casares‐Crespo, Talaván, & Viudes‐de‐Castro, ; Maranesi et al., ; Silva, Niño et al., ), but intramuscular administration of neither rabbit nor llama seminal plasma‐induced ovulation in receptive does (Cervantes, Palomino, & Adams, ; Silva, Niño et al., ). Seminal plasma treatment was, however, associated with an increase in the number of antral follicles and the presence of large haemorrhagic anovulatory follicles (Silva, Niño et al., ), similar to that observed after ovarian superstimulation of does with eCG (Garcia‐Ximenez & Vicente, ; Mehaisen, Vicente, Lavara, & Viuedes‐de‐Castro, ).…”
