A sperm analysis is the study of a semen sample. It is the most important study for evaluating male fertility. It is carried out macroscopically and microscopically. It analyses parameters such as pH, volume, liquefaction, viscosity, count, motility, viability and morphology. In addition, a capacitation test is carried out, which allows us to know the number of sperm recovered after processing the sample.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The parameters studied and their reference values are as follows:<\/p>

pH:<\/strong>\u00a0The pH should be between 7.2 and 8.1, though there is no evidence that a value of more than 8.1 is negative. However, lower values may indicate genital infection.<\/p>

Volume:\u00a0<\/strong>Volume should be more than 2 ml. If a sample is less than 2 ml it is termed hypospermia. A lower volume may indicate an obstruction caused by genital infection, congenital alteration of the vasa deferentia, or retrograde ejaculation.<\/p>

Liquefaction:\u00a0<\/strong>When it is collected, the sample is in a state of coagulation, and must be liquefied to proceed to its analysis. Liquefaction occurs after 20-30 minutes. If this does not occur it may indicate a dysfunction in the prostate.<\/p>

Viscosity:\u00a0<\/strong>Once liquefied, the semen should be slightly more viscous than water. If the sample is highly viscous, it may be due to a prostate dysfunction, frequent ejaculation, and\/or the psychological state of the patient. This increase in viscosity does not mean a direct cause of infertility, but may affect subsequent assessments of the seminogram such as its concentration and sperm motility.<\/p>

Sperm count:<\/strong>\u00a0Normal values should be above 20 million\/ml. If the value is below this, the sample is classified according to the number of sperm as follows:<\/p>
