Overview

Research has provided us with a successful program for the recovery, freezing, and artificial insemination of canine sperm cells from the testes of dogs that have died or have been neutered.

Whether your stud dog has passed away unexpectedly, suffered a medical emergency requiring neutering, or was neutered before you realized his genetic value — testicular harvest offers the opportunity to preserve his genetics for future breedings.

This service has been part of our program since we started in 2000, and we have helped breeders across the country recover and bank semen from dogs that would have otherwise been lost to their breeding programs.

This Is Extremely Time-Sensitive

Call us immediately when a dog dies or is neutered. Sperm viability decreases rapidly after death — the sooner the testes are recovered and processed, the better the chances of obtaining usable sperm. Every hour matters.

When Is Testicular Harvest Needed?

Unexpected Death

When a valuable stud dog dies suddenly — accident, illness, or unknown cause — testicular harvest can recover sperm cells before viability is lost.
Emergency Neuter

If a dog requires emergency neutering due to testicular torsion, tumor, or other medical condition, the removed testes can be harvested for sperm recovery.
Previously Neutered

In some cases, if the testes were preserved immediately in the right conditions, recovery may still be possible.
Genetic Preservation

For breeders who want to preserve a dog's genetics as an insurance policy for exceptional bloodlines.

The Harvest Process

1

Immediate Contact

Call us as soon as possible — ideally within hours. We will guide you through the next steps to preserve sperm viability.
2

Testes Recovery

The testes need to be removed by a veterinarian as quickly as possible. We provide handled guidelines.
3

Transport to Our Lab

The testes are transported to our facility in Grass Valley. Proper temperature during transport is critical.
4

Sperm Recovery & Evaluation

Our lab team extracts and evaluates sperm cells for motility, morphology, and viability.
5

Cryopreservation

Viable sperm is processed and frozen using our proven protocol and stored in liquid nitrogen.

Proper Preservation Is Critical

If a dog has passed, keep the body cool — not frozen. Refrigeration temperature is ideal. Do not freeze the testes. Call us immediately for specific instructions.

Success Factors

Time After Death

Sperm quality degrades rapidly. The first 24 hours are the most critical window.
Storage Temperature

Body or testes must be kept at refrigerator temperature — not frozen.
