The constituent cell types of the ovary of the porcupine were similar to those of New World hystricomorph rodents and accessory corpora lutea and luteal bodies were formed through the luteinization of the membrana granulosa or theca interna of antral follicles. All luteal bodies were histologically similar. The total volume of luteal tissue per female was not affected by fetal age and was unrelated to circulating concentrations of maternal plasma progesterone. Maternal plasma progesterone concentrations were correlated with fetal age. Follicular activity occurred throughout pregnancy but was not affected by fetal age or related to circulating values of oestradiol-17 beta. The formation of accessory corpora lutea during pregnancy is regarded as important in supplementing progesterone during pregnancy.
豪猪卵巢的组成细胞类型与新大陆豪猪亚目啮齿动物的相似，副黄体和黄体小体是由窦状卵泡的颗粒膜或卵泡内膜黄体化形成的。所有黄体小体在组织学上相似。每只雌性黄体组织的总体积不受胎龄影响，且与母体血浆孕酮的循环浓度无关。母体血浆孕酮浓度与胎龄相关。卵泡活动在整个孕期都有发生，但不受胎龄影响，也与雌二醇-17β的循环值无关。孕期副黄体的形成被认为在孕期补充孕酮方面很重要。
