Why A.I.?

Artificial insemination (A.I.) is the process of breeding animals with pre-collected sperm instead of using a live male animal. This process has positively affected the livestock industry by improved access to genetic diversity, decreased disease transmission, lowering risk of human injury, and it allows synchronized births.

When sperm is collected it is diluted, cooled or frozen then shipped to the female animal. When it is received it is warmed or thawed and injected into the female. This process causes damage to the cells. Damaged sperm can reduce the chances of pregnancy. Membrane Protective Technologies Inc. has developed technology that protects gametes and helps the odds of animals achieving and retaining pregnancy.

Who is MPTI?

Membrane Protective Technologies, Inc. is a research and development company that specializes in improving aspects of the reproductive industry. We offer custom cryopreservation services using GameteGuard® research for development on artificial insemination and embryos. MPTI’s scientific expertise ranges from andrology to bacteriospermiology and biochemistry to reproduction.

Patented Technology

MPTI’s suite of products (collectively GameteGuard®) includes patented technologies to protect gametes from the damages of freezing and thawing.

It is the quality of the spermatozoa that most affects fertility therefore when sperm cells are protected, more survive freezing/thawing.Those that survive are healthier and more likely to produce offspring.

GameteGuard® improves post-thaw sperm quality attributes by 30-50% and improves fertility by a corresponding 10 to 25% in dairy heifer breeding trials.
