In the case of male obesity, it has tripled in the population of childbearing age in the last 30 years, which also coincides with the increase in assisted reproductive treatments. However, there is limited and inconsistent information on the effect of male obesity on the results of assisted reproductive treatments.
The vast majority of studies report that there is no clear correlation between the increase in male BMI and semen parameters, and there may be other factors in the obese patient that decrease reproductive capacity, such as an increase in sperm DNA fragmentation. This correlates with the results shown by these studies in which those men with BMI >30, present a decrease in embryo development rates or an increase in miscarriage rates or home birth rates.
