Obesity strikes below the belt: Study reveals link between obesity and male infertility

The influence of obesity on male fertility is still under debate. In the present investigation, researchers scrutinized semen samples from both obese individuals and those of normal weight. The aim was to explore the relationship between obesity, the length of sperm telomeres, levels of mRNA associated with autophagy, and diverse semen characteristics.
