ct-9945	Card, Claire 	When and how to perform a transvaginal ovarian biopsy in a mare	2019	10	.pdf	application/pdf	4433	202	52	Keywords: Transvaginal ovary biopsy, mare, ovarian tumor Introduction Investigators have developed a variety of transvaginal ultrasound guided clinical techniques that have been applied to the equine ovary, e.g. follicle aspiration for oocyte collection (TUGA), trans- follicular oocyte transfer, luteal biopsy (TVLB) and ovarian biopsy (TVOB).1-3 Transvaginal ultrasound guided aspiration (TUGA) of follicles in the mare was reported in 1988.1 The TUGA procedure is repeatedly performed in mares to recover oocytes; ovaries of mares that had undergone many TUGA had fibrosis in the ovarian stroma, but there were no reported effects of repeated TUGA on fertility.4 Luteal biopsies in the mare and cow were described by Slough et al. and Aerts et al.5,6 Health and fertility effects of transvaginal ultrasound guided luteal biopsy (TVLB) along with transvaginal ultrasound guided ovarian biopsy (TVOB) in mares was reported, with fertility unaffected.3 The clinician should integrate results of transrectal palpation and ultrasonography, ovarian tumor biomarker analysis and ovarian biopsy in cases where the diagnosis is not straight forward.	cache/ct-9945.pdf	txt/ct-9945.txt
