Pathways to Pregnancy and Parturition, 2nd Ed: Figure 12-6A

The radiographs above are from extirpated cow reproductive tracts (dorsal view).  In cornual insemination, one-half of the semen is deposited in each uterine horn.  In both examples, the inseminant volume is 0.5-ml.  Cornual insemination minimizes the possibility of cervical deposition that results in significant retrograde loss of spermatozoa (See Figure 12-3).
