Morphometry of ovarian structures by transrectal ultrasonography in Serrana goats

The diameter of spherical CL could be estimated with reliability (r2 = 0.86; P < 0.001). The real-time ultrasonographic scanning proved to be a highly accurate method for detection and measurement of several categories of follicles and CL size in Serrana goats. The results of the present study show that laparoscopy and RTU are similarly reliable techniques for CL detection. However, the RTU represents a non-traumatic technique with advantages to animal welfare both in experimental and reproductive evaluation of the size of ovarian structures.
