Estudio comparativo de los parámetros del seminograma en una población de varones subfértiles consumidores de marihuana

Introduction

The aim of this work, is to find the prevalence of marijuana use in a subfertile population, and to carry out a comparative prospective study of the seminogram parameters of a group of subfertile patients, who are habitual marijuana users, versus a group of nested control cases of non-users.

Material and methods

2320 men were studied, 70% of patients from Primary Care Centers and 30% from hospital outpatient consultations. The analysis of sperm concentration and motility was carried out with a SCA® automated semen analyzer. The comparative study has been carried out, by applying a novel statistical methodology called «case-control nested», which is a hybrid case-control variation.

Results

The prevalence of marijuana use has been calculated in a population of subfertile men. Statistical analysis of the semen values of the group of marijuana users versus the control group shows that there are no significant differences between them.

Conclusions

In the group of subfertile men studied, a prevalence of 10.26% of habitual marijuana users was observed. In our results, no significant differences were observed between the two groups studied, so we are considering the additional performance of new sperm functionalism tests, to explain the subfertility that has been observed in some of these patients who use marijuana, who present a normal seminogram.
