The effect of boar seminal plasma was tested on the muscular activity of the uterine horns and of the isthmic part of the oviducts in anaesthetized oestrous gilts. The motility was recorded by using balloon-tipped catheters placed in the middle part of the uterine horns and in the isthmus close to the uterotubal junction. The following test solutionis were used: sperm-free seminal plasma and isotonic glucose solution. In the isthmic part a test solution called OLEP was also used. OLEP is a buffer solution with electrolyte concentrations, pH and osmotic pressure similar to seminal plasma. Neither seminal plasma nor the buffers used affected the motility of the uterine horns. Seminal plasma decreased the spontaneous motility of the isthmus, mainly characterized by a reduced amplitude. No effect was, however, obtained with the different buffer solutions used. It is therefore supposed that an unidentified substance with relaxative effect on the isthmic muscle is present in the boar seminal plasma.
在麻醉状态下的发情小母猪身上，测试了公猪精浆对子宫角和输卵管峡部肌肉活动的影响。通过将带球囊的导管放置在子宫角中部和靠近子宫输卵管连接处的峡部来记录运动情况。使用了以下测试溶液：无精子精浆和等渗葡萄糖溶液。在峡部还使用了一种名为OLEP的测试溶液。OLEP是一种缓冲溶液，其电解质浓度、pH值和渗透压与精浆相似。精浆和所使用的缓冲液均未影响子宫角的运动。精浆降低了峡部的自发运动，主要表现为振幅减小。然而，所使用的不同缓冲溶液均未产生影响。因此推测，公猪精浆中存在一种对峡部肌肉具有松弛作用的未知物质。
