Buying or selling a bull, buck, boar, or stallion?

Go beyond the breeding soundness exam. Sperm motility only tells part of the story. For a sperm to effectively fertilize an egg, it needs an intact acrosome and good quality DNA.

Do you know if your bull is producing good quality sperm?

Information drives value.

Buying straws?

It’s expensive to breed your animals.

If you know the sperm quality is good before you breed, you’ll have a greater chance at a calf, foal, kid or piglet. We can tell you how the sperm in your straw looks relative to other samples.

We will analyze the sperm cells, looking at acrosome quality, DNA quality, concentration, morphology, mitochondrial function, and motility

Want to know more before you breed?

Our quality control assay will provide you with an in-depth analysis of the quality of sperm. By conducting this test before you breed you won't waste time and money on low quality sperm.

We will give you a clear picture of how effective sperm will be and the likelihood of producing offspring. This way you know the quality of sperm before you inseminate females.

Cryopreservation with GameteGuardTM


Cryopreservation is the process of cooling and storing cells at very low temperatures to maintain their viability.  Unfortunately, the cooling and freezing process damages cells. In fact, cryopreservation can leave more than 50% of the cells damaged or killed.

Membrane Protective Technologies Inc's GameteGuardTM protects cells during cryopreservation. Contact us if you’d like to incorporate GameteGuardTM into your cryopreservation process.


In past decades diminishing fertility has led to over $300 million loss annually in the dairy industry.

One significant factor that causes reduction in fertility is the damage to sperm during the collection, cooling, freezing, thawing and handling. Damages can lead to the formation of free radicals.  Free radicals are uncharged molecules that are typically highly reactive. Their existence is necessary for a healthy sperm, but too many of them can have harmful effects. Too many free radicals can hurt the sperm's’ ability to move, it can damage the membrane, and harm DNA, all resulting in lower pregnancy rates.

Membrane Protective Technologies, Inc. developed a plant-based semen additive, GameteGuardTM, improves post-thaw sperm health and decreases the number of free radicals.

Quality Control Services

Sperm quality can greatly affect chances of pregnancy. Breeding Soundness Exams may not tell the whole story. BSE test overall breeding characteristics of the animal, but they do not do an in-depth sperm analysis. This means even after passing a BSE, the animal’s sperm could have issues, making achieving pregnancy difficult. What if there was a way to know more about semen quality before inseminating a female?  

Membrane Protection Technologies, Inc. will perform a custom sperm quality assay so that you can get the most out of artificial insemination. With this analysis you can increase the odds of pregnancy, and purchase the best straws.

What Quality Control Services Tell You

MPTI’s sperm quality assay evaluates eight key qualities of the sperm.


Motility: The ability of sperm to fertilize an egg based on its movement.

This is a video of sperm that is moving ‘correctly’ and is more likely to fertilize an egg. This is termed “progressive motility” and indicates a sperm is moving forward. You will see that this sperm is moving forward (not in circles) and the cells are not clumped. “Motility” or “Total Motility” just indicates the sperm is moving.

This video shows how the sperm is measured by a machine called a Computer Assisted Sperm Analyzer. This takes out all human bias and subjectivity in assessment of sperm quality.  Sperm that are moving progressively are indicated by green lines.  The red dot indicates the sperm was counted but is not moving.  Blue lines and yellow indicate the speed that the cells are moving.  A slow swimming cell can often be assumed to be of poor quality.


Sperm Quality: An evaluation of sperm cell health determined from the environment in which sperm lives.


Bacterial Load: The number of active bacteria contaminating the sperm.


Concentration: The total number of sperm cells in the sample.


Morphology: The percentage of sperm that present with no physical defects.


DNA Quality: The percentage of breaks in the DNA of the sperm cell.


Antioxidant Capacity: The level of antioxidants present in the raw ejaculate.


General Ejaculate Characteristics: The pH and osmolality show if the environment is optimum for the cells.

How it works

1. Call MPTI to arrange a test 970-484-9842
2. Decide what information you want to learn from the sample.
3. Ship us two/three straws of frozen semen per bull, or we can send a kit for collection.
4. We’ll email you the results, and be available to discuss them with you, or your veterinarian.
