How does PetCount™ work?

The PetCount device makes it possible to separate all the good swimmers, the Progressive Motile Sperm Cells (PMSCs) from the rest of the sperm population which include dead sperm cells, morphological abnormal sperm cells and motile but not the PMSCs.

The color reaction (test result) is a direct result of the number of PMSCs in the semen sample - the darker the better and the more PMSCs.

Sperm quality in dogs

The single most important factor in determining the sperm quality of a dog is the sperm cells ability to swim in a straight line, a term called Progressive Motility. The PetCount™ Sperm Quality Test for dogs measures the number of Progressive Motile Sperm Cells, PMSCs.

The semen factors thought to be most important to fertility are the motility, the number and the morphology of the spermatozoa. There is a direct relationship between sperm production by the testes and testicular size.
Therefore, larger dogs have a higher sperm count than smaller dogs. It has been reported that there is a relationship between sperm count and body weight. This may be true for animals in good body condition, but the relationship is lost in obese animals because testicular size does not increase. Even among breeds of similar size, there are variations in sperm counts.
