Obesity impacts human health in more than one way. The influence of obesity on human reproduction and fertility has been extensively examined. Bariatric surgery (BS) has been used as an effective tool to achieve long-term weight loss in both sexes. BS improves hormonal profiling, increasing the odds of spontaneous pregnancy and success rates following assisted reproductive techniques in infertile females. For obese males, BS does improve sexual function and hormonal profile; however, conflicting reports discuss reduced sperm parameters following BS. Although the benefits of BS in the fertility field are acknowledged, many areas call for further research, like choosing the safest surgical techniques, determining the optimal timing to get pregnant, and resolving the uncertainty of sperm parameters.

Keywords: Bariatric surgery, Male fertility, Female fertility, Assisted reproduction technique, Seminal fluid

Core Tip: One of the main strengths of bariatric surgery (BS) is achieving long-term weight reduction; many of the medical and dietary interventions have transient and sometimes ineffective results. Infertility is linked with obesity in many ways, including reducing the quality of produced gametes, disturbing the hormonal profile, and increasing oxidative stress, which in turn inversely affects many steps of human reproduction. BS can improve the fertility odds for both genders with assisted reproductive technique; additionally, it improves the odds of natural pregnancy.
