The ultrastructure of the high viscosity phase of human cervical mucus was studied by scanning electronmicroscopy. In the normal woman, sequential mucus samples taken throughout the menstrual cycle showed a honeycomb-like structure with interconnecting channels separated by thin membraneous walls. The diameter of the channels in the mucus was 2 to 6 mum in the early follicular phase, 30 to 35 mum in the late follicular phase and 4 to 6 mum in the luteal phase. During the first trimester of pregnancy and also at the beginning and end of the menstrual cycle a compact, dense form of mucus structure was observed. In women using either copper-releasing or pharmacologically inert intrauterine contraceptive devices (IUCDs), the basic structure was similar to that seen in normal women. The channel diameters were normal in women using the inert IUCD but the mucus from women using a copper-releasing IUCD showed a slight decrease in the late follicular phase channel diameter which was dependent on the time the device had been in place. Globular appendages to the membraneous walls of the mucus were observed in the presence of a copper-releasing IUCD.
通过扫描电子显微镜研究了人类宫颈黏液高黏度相的超微结构。在正常女性中，在整个月经周期采集的连续黏液样本显示出蜂窝状结构，有由薄的膜壁分隔的相互连接的通道。黏液中通道的直径在卵泡早期为2至6微米，卵泡晚期为30至35微米，黄体期为4至6微米。在妊娠的前三个月以及月经周期的开始和结束时，观察到一种致密、紧密的黏液结构形式。在使用含铜或药理惰性宫内节育器（IUCD）的女性中，基本结构与正常女性所见相似。使用惰性IUCD的女性通道直径正常，但使用含铜IUCD的女性的黏液在卵泡晚期通道直径略有减小，这取决于该装置放置的时间。在存在含铜IUCD的情况下，观察到黏液膜壁上有球状附属物。
