Deep Horn Insemination

Deep horn insemination is a technique that may be used to deliver spermatozoa to the tip of the uterine horn in close proximity to the utero-tubal junction. The procedure is most often used when the volume of semen is low or when frozen-thawed semen is inseminated. Deep horn insemination requires skill and practice in the correct placement of the pipette and transrectal manipulation of the pipette after insertion into the uterus, but the procedure can be accomplished on a farm with a little practice.
