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.
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 repro
