Scanning electron microscopic study of rabbit ovarian follicle microvasculature using resin injection-corrosion casts.

Abstract

The microvasculature of rabbit ovarian follicles was investigated three dimensionally with resin casting/SEM technique. Characteristic vascular patterns were revealed around the follicles of various developing stages. It is suggested that increased capillary permeability and congestion of the blood stream occurred just prior to ovulation.
