Infertility male obesity – Mechanisms linking obesity to male infertility

Reduction of the reproductive potential of obese men occurs due to changes in hormonal levels regulating spermatogenesis, increased temperatures in the testicles, environmental toxins accumulated in adipose tissue, increased levels of oxidative stress as well as a higher incidence of erectile dysfunction. Impact of obesity on female fertility and fertility treatment.
