The present studies indicated that the extensibility of the mouse uterine cervix was significantly increased by administration of as little as one unit of highly purified preparation of porcine relaxin. No significant change in tensile strength of the cervix was noted when doses were administered that caused increased cervical extensibility and formation of the interpubic ligament. A low coefficient of correlation was found between interpubic ligament formation and increased extensibility of the cervix in oestrogen-primed immature female mice.
目前的研究表明，给小鼠子宫颈施用低至一个单位的高度纯化的猪松弛素制剂，子宫颈的伸展性会显著增加。当给予导致子宫颈伸展性增加和耻骨间韧带形成的剂量时，未观察到子宫颈抗张强度的显著变化。在雌激素预处理的未成熟雌性小鼠中，耻骨间韧带形成与子宫颈伸展性增加之间的相关性较低。
