Histological characteristics of retrograde corpora lutea (RCL) were examined for 105 pairs of ovaries of adult female sika deer, Cervus nippon. Animals were captured in various seasons at Mt. Goyo, Iwate Prefecture, the northern part of Japan. No histological differences were recognizable between RCL of pregnancy and retrograde accessory corpora lutea (RACL), so far as examined by means of hematoxylin-eosin and Weigert's resorcin-fuchsin staining. They were both irregularly shaped and had well developed arteries in their thick capsules and a number of small arteries in the parenchyma. These arteries showed the proliferation of elastic fibers showing elastosis in older RCL. The total number of these retrograded bodies per female increased with age, suggesting that both the retrograded bodies would retain in the ovaries over 7 years. RCL of estrus were small hyaline bodies scattered with some degenerated luteal cells in the hyaline matrix. They were distinguishable from those of pregnancy since the capsule and parenchyma in those of estrus were poorer in blood vessels. RCL of estrus appeared in October and November but were rarely seen in February and March, suggesting that they will disappear within three months after ovulation.
对105对成年雌性梅花鹿（Cervus nippon）的卵巢进行了逆行黄体（RCL）的组织学特征检查。这些动物是在日本北部岩手县五所岳的不同季节捕获的。就苏木精-伊红染色和魏格特间苯二酚品红染色检查而言，妊娠的逆行黄体与逆行副黄体（RACL）之间在组织学上没有可识别的差异。它们的形状都不规则，厚包膜中有发育良好的动脉，实质中有许多小动脉。在较老的逆行黄体中，这些动脉显示出弹性纤维的增殖，表现为弹性组织变性。每只雌性动物这些逆行体的总数随年龄增加，这表明这两种逆行体在卵巢中会保留超过7年。发情期的逆行黄体是小的透明体，在透明基质中散布着一些退化的黄体细胞。它们与妊娠的逆行黄体不同，因为发情期逆行黄体的包膜和实质中的血管较少。发情期的逆行黄体出现在10月和11月，但在2月和3月很少见到，这表明它们将在排卵后三个月内消失。
