INTRA-UTERINE SEMEN DEPOSITION
The advantage of depositing semen in the uterus
was first realized when canine frozen was first utilized.
Conception rates increased six times when the canine frozen semen
was deposited in the uterus rather than vaginally. Two methods of
intra-uterine semen deposition are currently being performed at
Brownsville/Lomira Small Animal Clinic /International Canine Semen
Bank-Wisconsin.
TRANSCERVICAL INSEMINATION
uses a rigid endoscope to visualize the cervical
opening of the bitch. A flexible plastic catheter is guided through
the cervix into the uterus, where the semen is deposited. The
technique does not require sedation and causes no damage to the
vaginal tract, cervix, or uterus.
The drawback is that the uterine
lining, the weak spot in the bitch's reproduction cycle, cannot be
evaluated. This technique is best used on younger bitches (less
than three years of age) with no suspected uterine damage when
using compromised quality fresh-cooled or frozen semen.
