Third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (Goetz technique). Primary healing occurred in all of them without any complication. The conception rate obtained after surgery was 70.1%. Five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. Three mares have produced several healthy foals without any ...
