How Purdue helps with mare breeding management
The Equine Theriogenology Service provides semen collection services for stallions at the Purdue University Equine Hospital.
Because each stallion and breeding plan is different, owners should contact the service before scheduling to discuss the stallion’s history, collection experience, breeding goals, and any needed records.

Semen freezing and cryopreservation
Semen freezing, also called cryopreservation, can help preserve stallion genetics for future use. The Equine Theriogenology Service provides semen cryopreservation and semen storage for stallion owners.
Semen freezing requires collection, evaluation, processing, and storage planning. The team can help owners understand what information is needed before an appointment and what to expect during the process.
If you are considering semen freezing, Call us at 765-494-8548 to discuss timing and scheduling.

Semen storage
The Equine Theriogenology Service provides semen storage for frozen stallion semen.
Owners may need semen storage as part of a breeding plan, long-term genetic preservation, or future reproductive planning. Contact the service to discuss storage needs, records, and next steps.
Phantom training
Some stallions need training before they can safely and calmly participate in semen collection. The Equine Theriogenology Service provides phantom training for stallions as part of its reproductive services.
Phantom training may be appropriate for stallions that are new to collection, have limited collection experience, or need additional handling and training before semen collection is practical.
Call us at the service to discuss whether phantom training may be appropriate for your stallion.
Stallion fertility evaluation
The Equine Theriogenology Service evaluates stallions with fertility concerns or questions about reproductive performance.
A stallion fertility evaluation may be recommended when:
- A stallion has not produced expected pregnancy results
- Semen quality or collection history is a concern
- The owner is planning semen freezing
- The stallion is being prepared for breeding season
- A veterinarian recommends reproductive evaluation
The team can help determine what records, semen history, breeding history, or prior evaluation findings may be helpful before an appointment.

Post-mortem gamete preservation
The Equine Theriogenology Service provides post-mortem gamete preservation for stallions when circumstances allow.
This service may be considered in time-sensitive situations involving illness, injury, death, or planned euthanasia when genetic preservation is a concern. Because timing is important, owners or veterinarians should call 765-494-8548 as soon as possible to discuss whether post-mortem gamete preservation may be an option.
