Corpora lutea from gerbils on days 1, 4, 8, 12, 16, 20, and 24 of pregnancy were studied electron microscopically. Similarly, luteal tissue from animals on the day of parturition and one day postpartum was studied (gestation: 24 days +/- 8-24h). Agranular endoplasmic reticulum increases in quantity through day 16 and thereafter is somewhat reduced. Granular endoplasmic reticulum and a population of small granules (type I) become abundant during late pregnancy and their possible role in the production and storage of relaxin is discussed. Luteal tissue undergoes a relatively rapid regression which begins on the day of parturition. Conspicuous in the regressing luteal tissue are large (type II) granules (possibly lysosomes), lipid droplets, leucocytic elements and macrophages. Functional correlates of these morphological findings are discussed.
对妊娠第1、4、8、12、16、20和24天沙鼠的黄体进行了电子显微镜研究。同样，对分娩当天和产后一天动物的黄体组织进行了研究（妊娠期：24天±8 - 24小时）。无颗粒内质网的数量在第16天前增加，此后有所减少。颗粒内质网和一群小颗粒（I型）在妊娠后期变得丰富，并讨论了它们在松弛素产生和储存中的可能作用。黄体组织在分娩当天开始经历相对快速的退化。在退化的黄体组织中明显可见大的（II型）颗粒（可能是溶酶体）、脂滴、白细胞成分和巨噬细胞。讨论了这些形态学发现的功能相关性。
