The case records of 47 mares with third-degree perineal lacerations or rectovestibular fistulae were examined to evaluate their fertility following surgical repair. Of 32 mares bred, 24 became pregnant, suggesting that surgical repair is indicated in any mare with sufficient genetic potential. Perineal trauma after surgical repair was recorded in 3 of 20 mares at subsequent parturition.
对47匹患有三度会阴撕裂或直肠前庭瘘的母马的病例记录进行了检查，以评估手术修复后的生育能力。在32匹配种的母马中，24匹怀孕，这表明对于任何具有足够遗传潜力的母马都应进行手术修复。在随后分娩时，20匹母马中有3匹记录到手术修复后出现会阴创伤。
