The microvasculature of rabbit ovarian follicles were investigated three-dimensionally with resin casting/SEM technique during ovulation and corpus luteum formation. The basic vascular pattern around Graafian follicles remains essentially unchanged, except for expansion of the blood vessels to keep pace with follicle growth, until ovulation occurs. The resin leaked out from the inner capillary wreath and could not get into the apical vessels just prior to ovulation. These findings indicate the increased capillary permeability and congestion of blood stream at the apical region shortly before ovulation. At 3-5 hours after ovulation, the unusually dilated vessels were developed into the follicular cavity, and then the fine vessels in radiating arrangement sprouted from the theca capillary wreath in one or two days. There seems to be regulatory roles of vascular systems in ovulatory and luteinizing process.
在排卵和黄体形成过程中，采用树脂铸型/扫描电镜技术对兔卵巢卵泡的微血管系统进行了三维研究。直到排卵发生，除了血管扩张以跟上卵泡生长外，格拉夫卵泡周围的基本血管模式基本保持不变。就在排卵前，树脂从内部毛细血管环漏出，无法进入顶端血管。这些发现表明排卵前不久顶端区域的毛细血管通透性增加和血流充血。排卵后3 - 5小时，异常扩张的血管延伸至卵泡腔，然后在1 - 2天内，从卵泡膜毛细血管环长出呈放射状排列的细小血管。血管系统在排卵和黄体化过程中似乎具有调节作用。
