“…The abscess was found after aspiration of a haemorrhagic structure that formed after a TVA, in an ovary noted on initial examination as difficult to manipulate. Nevertheless, this finding, combined with the similar report of Bogh et al [10], indicates that abscess formation is a rare but potential consequence of follicle aspiration.…”

“…There is one previous report of death of a mare due to haemorrhage resulting from arterial puncture during TVA [9]. Bogh et al [10] reported the development of an ovarian abscess in one of 4 pony mares subjected to repeated TVA (average of 121 follicles aspirated per mare) over an 8-year period. To the best of our knowledge, the latter is the only report available on the effect of repeated TVA of immature follicles on ovarian status in mares.…”

SummaryReasons for performing study: Transvaginal ultrasound-guided follicle aspiration (TVA) is performed clinically but there is little information available on complications associated with this procedure. Objectives: It is possible that TVA is associated with damage to the ovary and may induce peritonitis or peritoneal adhesions. This study was conducted to determine the effect of repeated TVA on mare health and ovarian status. Methods: Thirty-two mares were used for oocyte recovery via repeated TVA over a 3 year period; different mares were used each year. In Year 1, ovarian status was monitored in 11 mares by transrectal palpation and ultrasonography. In Year 2, 6 of 11 mares underwent abdominocentesis and were examined by laparoscopy after one TVA and again after multiple TVAs. In Year 3, 10 mares underwent multiple TVAs with either a 15 or a 12 gauge needle and the ovaries were removed for examination. Results: Four hundred and twenty-seven aspiration sessions (390 via TVA and 37 via needle placement through the flank) and 3202 follicle punctures (3161 TVA and 41 flank) were performed. One mare developed an ovarian abscess. Transient rectal bleeding was evident after 16% of TVA sessions. No adhesions were found on laparoscopic or gross examination of ovaries and there were minimal changes on histological evaluation. Conclusions: Follicle aspiration carries a small possibility (<0.5%) of ovarian abscess formation. There is a possibility of rectal abrasion or puncture but little gross or histological damage to the ovary. Potential relevance: These results provide a basis for using prophylactic administration of antibiotics after TVA and for advising mare owners of the rare but potential complications associated with the procedure.

A mean of 19 puncture sessions were performed and 122 follicles were punctured per mare; the oocyte recovery was not given (Bøgh et al 2003). The mares continued to have normal oestrus cycles; however, evaluation of the ovaries on removal showed one mare to have ovarian abscesses.…”

Contents In vitro embryo production is possible in the horse both clinically and for research applications. Oocytes may be collected from excised ovaries post‐mortem, or from either immature follicles or stimulated pre‐ovulatory follicles in the live mare. In vitro maturation of immature oocytes typically yields approximately 60% mature oocytes. As standard in vitro fertilization is not yet repeatable in the horse, fertilization is performed by intracytoplasmic sperm injection. Embryo culture requires medium with high glucose, at least during blastocyst development, and rates of blastocyst development similar to those for cattle (25% to 35%) may be obtained. Pregnancy rates after transfer of in vitro‐produced blastocysts are similar to those for embryos recovered ex vivo.
