Sperm Diagram | Sperm Enrichment

Sperm diagram: This test checks the quality of semen, identifying sperm concentration, motility and morphology.

The characteristics of a normal sperm diagram are:

Volume	2.0 – 5.0 cm3
pH	7,2 - 8,0
Concentration	> 20 million/ml
Total number	> 40 million/ejaculate
1st hour motility	> 50 % directly forward moving spermatozoa
Viability	> 50 %
Morphology	> 30 % normal spermatozoa
White blood cells	< 1 million

A semen sample is characterized by:

oligospermia when the number of spermatozoa is lower than normal (<20 million/ml)
asthenospermia when the percentage of motile spermatozoa is low
oligoasthenospermia when both the number and motility are lower than normal
teratospermia when a high percentage of malformed spermatozoa is observed
azoospermia when spermatozoa are completely absent.

Sperm enrichment: Enrichment is recommended in cases where the value of one or more semen parameters are not within normal range. This is a special process to improve semen characteristics, in order to be used for IUI insemination or for IVF-ICSI.
