Male Body Mass Index and Seminal Parameters
Objective: to evaluate the controversial association between body mass index (BMI) and seminal fluid parameters of male patients who consulted with their partners in our clinic. Design: retrospective observational study including 1009 males attended in Instituto FIVIR from January 2010 to January 2018. The following parameter s are registered: height (meter) and weight (kg) in order to obtain BMI (kg/m2), age, fresh spermatic count (m/mL), progressive motility (%) and normal morphology (%). Patients: Of 1009 selected patients, only 471 met the inclusion criteria for the present study. All of them were European, white males, who obtained the seminal sample at our center (after three days of abstinence and no history of fever the previous four weeks). When the analysis had to be repeated in the same patient, we included only the first analysis in the study. Conclusions: In the present study, a BMI increase was associated with a decrease in sperm quality, affecting both concentration and motility. Sperm morphology was not affected.
