Resolution of two cases of ovarian abscesses in mares subjected to ovum pick up.

Background: Currently, for in vitro embryo production in live mares, immature oocytes are retrieved by transvaginal follicular aspiration or ovum pick up (OPU). Occasionally, ovarian abscesses have been described after OPU, but no current consensus exists on how to treat this condition.

Objectives: To describe diagnosis and successful treatment of ovarian abscesses in two mares subjected to OPU.
