The evaluation of sperm quality through a spermiogram
In order to determine why some couples cannot conceive children naturally a spermiogram is routinely made to evaluate the quality of the man’s sperm. The following sperm quality criteria must be met in order to conceive a child naturally:
Density (sperm count):
Over 10 million sperm per ml ejaculate is necessary.
Motility (movement of sperm):
Over 20% should be normally mobile.
Morphology (shape of sperm):
Over 30% should be of normal shape.
