Sperm analysis anomalies

On numerous occasions we find alterations in the semen analysis of the patients without this necessarily meaning that there is a health or infertility problem.

However, certain alterations should alert us to the need to repeat a seminogram in a short period of time to confirm or rule out the findings.

In 2010, the WHO established new reference values ​​for the evaluation of the seminogram that are the following:

The 2010 normal values are:

Volume≥1.5 ml
Total concentration≥39 millions
Concentration par ml≥15 millions/ml
Total motility≥40%
Progresive motility (a+b)≥32%
Normal morphology≥4%
Leukocytes<1 million/ml

These reference values ​​serve to guide the diagnosis and treatment of couples who do not achieve pregnancy spontaneously, but they do not mean that a male with results within the normal ranges is necessarily fertile, nor is a male whose results are out of normal ranges is completely sterile.

Some alterations that we can find are:

HYPOSPERMIA: ejaculate volume less than 1.5 milliliters.

AZOOSPERMIA: absence of sperm in the ejaculate.

CRYPTOZOOSPERMIA: few sperm in the ejaculate.

OLIGOZOOSPERMIA: less than 15 million sperm per milliliter.

ASTHENOZOOSPERMIA: mobility less than 32%.

NECROZOOSPERMIA: vitality less than 58%.

TERATOZOOSPERMIA: normal morphology less than 4%.

LEUCOSPERMIA: presence of more than 1 million leukocytes per milliliter of ejaculate.

The correct evaluation of each of these parameters may guide us to a possible male origin of the couple’s infertility, to adopt the necessary measures to improve the altered parameters.

An evaluation by a specialist in andrology is recommended, especially in the most severe cases, to rule out other types of problems at the genitourinary level.
