CONCLUSION
In conclusion, obesity could impair oocyte quantity and quality in younger women through altered endocrinology and poor follicular microenvironment, which, in turn, impairs CLBR. Maternal obesity is also closely associated with HDP and fetal macrosomia among younger women, which could raise the birth risk and economic burden. Since being overweight and obese adversely affects IVF/ICSI outcomes, weight loss management may improve pregnancy outcomes and safety among younger women with elevated BMI. Further randomized controlled trials of lifestyle or pharmacological interventions prior to IVF/ICSI procedures in overweight and obese women are needed to determine whether the short- and long-term adverse effects for both mothers and their offspring could be reduced.
