The following factors influence sperm quality:

Speed
Motility
Morphology
Count
Concentration

Speed is the ability to quickly reach the egg to be fertilized. Motility refers to the ability to move up the cervical channel in one direction to the egg, while morphology refers to shape as well as the size of a healthy sperm. Count indicates the amount of sperm present in the male semen. Concentration is how well the sperm is presented in the semen when counted per millilitre. If any of the above shows abnormalities then the sperm quality will drop. Poor sperm quality will influence the ability to successfully conceive and will also influence the health of the foetus. As such any supplement for male fertility should address all five factors to be effective. The Pregassist for men supplement addresses all five factors, which is why it is such an important product to improve male fertility.
