About Us

Our Technology

MPTI has worked hard to develop a technology that makes breeding using artificial insemination more effective. GameteGuard® is an organic semen extender-additive developed by MPTI that protects the sperm cell membrane. This means sperm is kept healthy and more effective.

MPTI’s suite of products includes patented technologies to protect sperm from the damages of cooling, freezing and thawing. The damages that occur can result in lower pregnancy rates. Fertility is most affected by the quality of sperm, so protecting sperm cells results in a higher chance of offspring.

J.A. Herickhoff, CEO has significant experience in development, creation, commercialization and growth of a technology and of a company. He has a proven record of growth. For example, he led the growth of the Black Thunder Coal Mine from 18 to 40 mm tons per year and in the process became the world’s largest coal mine.

He has experience inventing, developing and leveraging patentable technology, and sits on the boards of two multi-million dollar companies and three start-up companies and brings this breadth and depth of hands-on experience and knowledge to MPTI

Dr. L.A. Herickhoff

The President, Dr. L.A. Herickhoff is a scientist with 10 years of industrial science expertise including antioxidant and andrology technologies. Her expertise in antioxidant technology includes having scaled up the application of antioxidant treatments for produce from the laboratory to an industrial application for the corn industry (Pioneer Corn) and the mushroom industry (Monterey Mushroom; Clean N Ready™ technology) at EPL Technologies, Inc.

In addition, she has significant IP development and protection experience having participated as an inventor or author on over 19 patents and trademark applications.  She is the inventor on 13 patents including those relating to antioxidants and many others relating to sperm, some via her employment with XY, Inc., the pioneer in sperm sexing technology. Scientific sales and small-business development experience helps to round out her suite of skills.

Word from the President

Our family has been on the same dairy farm in Germany since the 1600's. When my Grandfather left that farm in the capable hands of his brother and came to the US he settled in Minnesota and founded a dairy which is still run by one of my Uncles. While my Dad walked away from farming, I was fortunate enough to be able to spend time on the dairy and learn this way of life. In addition, I have a passion for horses, and animals in general.
This company allows me to combine my love of science, my love of animals, and my desire to contribute to my family's heritage. More specifically, my background in commercializing a technology from the idea stage to the market ready stage, my knowledge of antioxidants, my experience in sales and my understanding of reproduction are all brought to bear and I feel so blessed to be able to combine all of these passions into one venture!
MPTI’s team of employees is highly technical (2 PhD, 2 M.S.) having expertise in biochemistry, microbiology, andrology, and plant biology. Business advisors and consultants have been retained as part of the licensing opportunity in bull sperm.


The following publications document experiments conducted to test the effects of GameteGuard® on reproduction efficiency. The experiments document the positive effects of GameteGuard® on pregnancy rates and sperm health.
