Abstract

Histological analysis of the ovarian function of 415 female zebus emphasizes: -- A discontinuous genital cycle, characterized by periods of sexual rest which can last for three months or more. -- The late appearance of the degenerative phase of the corpus luteum which, at the beginning of the following cycle, still often presents images of functional activity. -- Atretic follicles which appear under three aspects whether the ovum or the granulosa persist or disappear. -- Corpora lutea of pregnancy which are usually replaced two or three times before parturition.

摘要

对415头母瘤牛卵巢功能的组织学分析强调:——生殖周期不连续,其特征为性休止期可持续三个月或更长时间。——黄体退化期出现较晚,在下一个周期开始时,黄体仍常常呈现功能活跃的图像。——闭锁卵泡呈现三种情况,即卵子或颗粒细胞持续存在或消失。——妊娠黄体通常在分娩前会更替两到三次。
