Click an item to see its the sperm glyph for a human sperm in that category.

Grade A

Grade A

Sperm with progressive motility. These cells are the strongest and swim fast in a straight line.

Note the relative agreement of the VCL, VAP and VSL measures.

Grade B

Grade B

These also move forward but tend to travel in a curved or crooked motion.

Note the VCL increasing noticably compared to the VAP as the cell meanders.

Grade C

Grade C

These have non-progressive motility because they do not move forward despite the fact that they move their tails.

Note that no VCL, VAP or VSL values are available in the data.

Grade D

Grade D

Sperm with progressive motility. These cells are the strongest and swim fast in a straight line.

Note the relative agreement of the VCL, VAP and VSL measures.

Hyperactivated

Hyperactivated

Hyperactivated sperm, exhibiting asymmetric and irregular beat patterns and high velocities associated with fertilization and penetration of the oocyte.

Average

Average

The sperm of the Average Joe.
