Obesity has been linked to infertility through several mechanisms, including at a molecular level. Those living with obesity face additional barriers to accessing fertility treatments and achieving a successful pregnancy, which can contribute to their economic and psychosocial stressors. There is scope to further improve care for people living with obesity and infertility with empathy, via a multidisciplinary approach. Synopsis: Obesity is linked to infertility at a molecular level and those living with obesity face additional barriers in accessing fertility treatments, which contribute to economic and psychosocial stressors.
