Advanced Fertility Center

PS - Embryo Transfer 300xIn 1999 Peterson Smith established the state-of-the-art reproductive center. Situated in the southern part of Marion County, the Peterson Smith Advanced Fertility Center (PSAFC) conducts all aspects of assisted reproduction at its Summerfield, Florida facility. As part of the embryo transfer (ET) program we maintain one of the largest recipient mare herds in the southeastern United States. This herd of carefully selected recipient mares has allowed us to enjoy an extremely successful ET program for over 20 years. Our experience, expertise and facilities allow us to offer different options by which a breeder can participate in a successful ET program. 

Equigea - 300xThe Advanced Fertility Center has been on the cutting edge of reproductive technology since its inception. In March 2003, PSAFC was the first commercial veterinary operation to produce a foal from a frozen embryo in the southeastern United States. The entire process was performed by Peterson Smith veterinarians and staff. They are proud to continue the tradition of staying on the cutting edge of technology by partnering with Equigea.  Equigea offers everything in-house at PSAFC to produce embryos from intracytoplasmic sperm injection (ICSI).  Including aspiration of oocytes (eggs; OPU), maturation of oocytes, ICSI, embryo development, transfer to recipient mares and service for shipped oocytes.

frPSAFC also offers a full line of stallion services allowing owners to utilize their stallions in a fresh, cooled/shipped, or frozen semen breeding program. As a proud member of the Select Breeders Services Affiliate Network, we can offer our clients the leading frozen semen program in the industry. The program is designed to provide optimal service and adheres to the strictest quality control standards in the industry.  PSAFC is also USDA approved for export of equine semen outside of the United States, allowing stallion owners to take full advantage of Select Breeders Services' international network of laboratories for storage and distribution of frozen semen.
