What to Expect During Your Appointment

Your scheduled visit to the Theriogenology Service at the Cornell University Hospital for Animals begins with a check-in at the reception desk. Following a small amount of paperwork, you will be greeted in the waiting room by one or two students rotating on the Theriogenology Service and be taken to a private examination room. Once there, the students will collect information about your animal's history and then perform a physical examination. We appreciate your patience and understanding in allowing these future veterinarians to interact with you and your pet.

The students will then consult with our residents and faculty regarding their findings and assessments. A resident or faculty member will accompany the student back into your examination room and will examine your pet again and then discuss a plan to reach a diagnosis, including optional next steps, cost and logistics.

Often, you will be asked to leave your pet in our care so that we can begin appropriate testing. Given our schedule and consultations with other specialists regarding your pet's care, you may be asked to return to discuss the findings later in the day. Some animals with more serious conditions will be admitted to the hospital for further monitoring and treatment.

Reproductive Medicine: Medical Conditions

Breeding management

We can help plan the breeding of your bitch well in advance. Typically, we start seeing bitches soon after owners notice the first signs of estrus or heat. By examining her three times a week and measuring her blood progesterone concentrations, we can determine the ideal time for insemination to maximize fertility and litter size. We can assist in management of natural breeding, artificial insemination with fresh, cooled-shipped, or frozen semen. We can provide an accurate expected whelping date and monitor the health of the bitch and the fetuses during pregnancy. Similarly, we can assist in collection of semen for local insemination, cooled-shipment elsewhere or cryopreservation for later use.

We also offer investigation of infertility of male and female animals, including investigation of anatomical and functional abnormalities, semen analysis, screening for infectious diseases, endometrial or testicular biopsy and appropriate treatment. We offer full breeding soundness exam and partner with medical geneticists.

In appropriate cases, we offer medical treatment of pyometra and manage the subsequent breeding of affected animals. We also assist with management of benign prostatic hyperplasia of breeding dogs to maintain fertility.

Obstetrical complications

If you are unfortunate enough to experience complications during whelping or queening, we provide assistance with medical and surgical management of obstetrical cases.
