Abstract
ObjectiveTo determine the implication of general physical activity and some specific sports in semen quality in men from infertile couples. Study designThis is an observational study performed in men from infertile couples (n = 454). The interventions performed involved analyzing semen quality parameters according to 2010 WHO criteria and assessing physical activity by means of an International Physical Activity Questionnaire. Result(s)There was no association between different levels of general physical activity and semen parameters. We neither found association with running, cycling and racquet sports. Interestingly, people who practice weightlifting more than two hours per week presented significantly lower sperm concentration (linear coefficient = −24.80) and lower total sperm count (linear coefficient = −70.87) in comparison with participants that did not practice regular exercise. Conclusion(s)From a reproductive point of view, there does not seem to be any reason to recommend the increase or the decrease in general physical activity in males from infertile couples. However, additional studies are needed to investigate the relationship between weightlifting and sperm quality.
