Worldwide, around 15% of the couples suffer from infertility; male factor has been linked to more than 50% of the cases. Several studies from different countries have tried to detect temporal trends in semen quality, reaching controversial findings. Only a few of them aimed to establish an association between trends in semen quality and possible explicative factors. The aim of this observational descriptive study was to analyze the possible variation in seminal quality during the last 20 years (2011 to 2020), evaluating 23130 semen samples from patients attending an andrology center (Laboratorio de Andrología y Reproducción ?LAR-), and to identify possible explicative lifestyle and/or environmental factors.After the sign of the informed consent, all the patients attending to LAR were recluted. Those with age or abstinence out of the range (20-60 years and 2-7 days respectively) were excluded. The 20 years period was divided in four subperiods of five years each (P1-P4). Data of semen analysis, body mass index and lifestyle/environmental factors were evaluated by Chi square test and logistic regression. We found a significant increase (p
