Abstract

Introduction: About half of the couples who have difficulty conceiving have a male factor for infertility.

Objective: To associate lifestyle and dietary factors with semen quality in a pre-pregnancy clinic in Ecuador. 

Methods: Semen analysis and dietary and lifestyle data were collected from 102 men. Binary logistic regression and Cohen's kappa test were used.

Results: Smoking was significantly related to Progressive Motility Quality (β = 1.854, p ˂ 0.001), while Alcohol Consumption showed significant association with both Progressive Motility and Progressive Motility Quality (β = 1.212, p = 0.013). However, Sweet Diet, Dairy Intake, Frequent Egg Consumption and Adequate Sleep did not show a significant relationship with any of the sperm motility variables. Cohen's Kappa value for Progressive Motility Quality was 0.509 (50.9 %), showing the success of the predictive model. On the other hand, in the context of Total Motility Quality it was 0.314 (31.4 %), demonstrating the effectiveness of the predictive model.

Conclusions: Overall there was no statistically significant relationship between Progressive and Total Motility Quality with the predictor variables, so there was no evidence to reject the null hypothesis (H0).
