FSFI after operation was significantly and negatively correlated with age (r=− 0.383; p< 0.01), menstrual cycle (r=− 0.202; p< 0.05) and VAS (r=− 0.661; p< 0.01). FSFI before and after operation were not significantly correlated with BMI and comorbidity (p> 0.05). Age (OR=− 0.083; p< 0.01) and VAS (OR=− 0.410; p< 0.01) had significant and negative effect on FSFI before operation. Similarly, age (OR=− 0.092; p< 0.01) and VAS (OR=− 0.439; p< 0.01) had significant and negative effect on FSFI after operation.Conclusion: Menstrual cycle change after LSG also had a decreasing effect on FSFI level after obesity. Therefore, treatment support can be given to women in terms of menstrual cycle in order to increase their sexual quality of life after LSG. Multidisciplinary studies of bariatric surgeon and gynecologist are needed in this regard.Keywords: laparoscopic sleeve gastrectomy, sexual function, obesity, female sexual function
