Evaluation of anti-Müller hormone AMH levels in obese women after sleeve gastrectomy

Abstract Introduction: The link between obesity epidemic in fertile age and fertility reduction, in relation with BMI increase, has been demonstrated. An inverse proportionality between BMI and anti-Müller hormone (AMH) has been investigated. This hormone is strictly related to ovarian function. It has been demonstrated that...
