Subfertility in Stallions

There are many causes of sub-fertility in stallions. The key to successful management is correct diagnosis of the underlying cause. The cause can simply be an affect of aging or a primary pathologic condition. Once the cause is identified, proper strategies for collection, semen processing and insemination timing can be developed. Our large herd of recipient mares enables us to conduct fertility trials in order to determine the best protocol for optimum results. Some strategies include:

• Cushioned Centrifugation
• Seminal Plasma Replacement.
• EquiPure Centrifugation (Density Gradient Centrifugation)
• Fractionated Semen Collection
• Chemical Ejaculation

Subfertility in Mares

Close monitoring and diligent preparation of the mare's uterus provide our doctors with the necessary information to develop a plan catered to each mare's specific needs and issues. This individual care along with our on-site diagnostic capabilities and outstanding embryo recipient herd allow us to garner success in even the most difficult cases.

HERC's program for obtaining successful results in the Subfertile Mare involves the following techniques:

• Optimal timing for obtaining uterine cultures
• Timing of insemination relative to ovulation
• Specific uterine therapy that minimizes complications associated with broad spectrum intrauterine antibiotics
• Aggressive techniques to aid with uterine clearance
