An abdominal CCD camera for the continuous video recording of sheep ovary images during the reproductive cycle

An intra-abdominal ovary-isolating observation system based on a charge-coupled device (CCD) camera and intended for continuously recording video images of the ovary during the reproductive cycle was constructed and surgically implanted in ewes. A time-related label was generated automatically for the identification of each frame. Results demonstrate the importance and unique capabilities of bio-implantable cameras for long-term studies.
