Abstract

Abstract: A cross‐sectional pilot study was conducted in men followed in fertility consultations, from the portuguese Trás‐os‐Montes and Alto Douro region, in order to associate several lifestyle factors with the spermatic parameters. Of a total of 522 men, 373 were compared based on the occupational exposure to harmful factors, smoking habits and practice of physical exercise per week, and the other 149 men according to their body mass index (normal weight vs. overweight vs. obesity). In the absence of harmful occupational factors, physical exercise seems to be associated with sperm quality improvement, whether individuals smoke or not. When exposed to harmful environments, non‐smokers that practice physical exercise more than two times per week tended to present the best vitality, normal morphology and sperm concentration ( p > .05). However, if they smoke, physical exercise seems not enough to enhance the spermatic parameters. The BMI correlated negatively with the spermatic quality, especially with sperm concentration ( p < .05). Concerning men that did not present lifestyle risks associated, the motility, midpiece and tail abnormalities, and teratozoospermia index were significantly worse on obese individuals comparing to overweight men ( p < .05). Thus, patients should also be recommended to control their weight and to have a BMI under 30 kg/m 2 .
