Research output: Contribution to journalArticlepeer-review


Six oocytes were aspirated from preovulatory follicles of 18 mares via surgical exposure of the ovary (5/13) or percutaneous needle aspiration (1/5). Surgical transfer of the oocytes into the oviduct of mares previously inseminated with 500 × 106 progressively motile spermatozoa resulted in no embryos recovered by uterine lavage 8 days afteroocyte transfer. Corpora luteal function and formation from aspirated follicles appeared normal, based on progesterone analysis, ultrasound morphological assessment and cyclic behavioral changes.
