Introduction:

As of the present moment many studies have evidenced a decline in the quality of the human semen and an incremented risk masculine sub-fertility.

Objective:

To evaluate the association's grade of the morphologic and functional changes of the spermatozoa with the risk factors in the masculine infertility.

Methods:

A descriptive transverse study was carried out in the 123 patients with alterations in the spermogram attended in the Territorial Center of Attention to the Infertile Couple in Holguín in the year 2021, and that fulfilled the established criteria of inclusion and exclusion. The information was gotten from the revision of the case histories and the realization of a questionnaire. Spearman's correlation to identify the relation between the studied variables was used.

Results:

The teratozoospermia was the morphofunctional change that predominated with 69 cases (56.09 %), being more frequent in the age bracket of 30 to 39 years (22 for a 76 %), the exposition to temperatures raised with 19.51 % and the varicocele with a 43.9 %. The malnutrition for excess and teratozoospermic in 44 patients evidenced a bigger association in the correlation of the studied variables.

Conclusions:

The evaluation of the changes allowed morphologic and functional of spermatozoa knowing a predominance of the related to the morphology. Risk factors like an age older than 30 years, the malnutrition for excess, the exposition to loud temperatures and the varicocele correlate to the masculine infertility.
