[Relationship between male age and semen quality. Experience at the number 14 health-care area of the Valencia health-care agency].
OBJECTIVE
Spermatic count and number of mobile forms are two very important parameters for the measurement of spermatic quality by means of sperm analysis. Numerous factors such as obesity, smoking, environment contamination, stress, or age act modifying the sperm fecundation capacity, therefore they interfere in the numbers of this two variables.


METHODS
We aim to study the influence of age on semen quality. We studied 156 patients. They were divided into three groups: 20-30 years; 31-40 years; and 40-50 years. A Mackler's camera and a Nikon microscope were used for evaluation.


RESULTS
Nonparametric statistical study was performed establishing the relationship between sperm count and mobility and age. Age-count: X2: 8.239 (p = 0.016). Non mobile spermatozoids-age: X2 = 6.871 (p = 0.032). Mobile spermatozoids-age: X2 = 7.378 (p = 0.025).


CONCLUSIONS
The age of the patient is intimately related to a decrease of the number of spermatozoids, with the decrease of the number of mobile forms and the increase of the non mobile.
