This involves the complete eversion of both horns of the womb which turn completely inside out. It usually takes place within 2-4 hours of the completion of farrowing but sometimes up to 24 hours afterwards. Prolonged straining causes a small part of the tube to be propelled outwards by uterine contractions.
