Obesity and Increased Risk for Oligozoospermia and Azoospermia [PDF]

Archives of Internal Medicine, 2012
The global obesity epidemic parallels a decrease in male fertility. Yet, the association between body mass index (BMI) and sperm parameters remains controversial. A negative correlation between BMI and sperm concentration or total sperm count (TSC) was shown by several reports,1, 2 but not documented by others.3, 4 The purpose of this report was to ...
