Benito E, Gómez-Martin JM, Vega-Piñero B, et al. - Researchers conducted this unicenter cohort study to analyze fertility and gestational outcomes in women with polycystic ovary syndrome (PCOS) after bariatric surgery. Before bariatric surgery, 216 premenopausal women were screened for PCOS. Study participants were followed-up after the intervention until mid-2019 despite having or not PCOS. From 2005 to 2015, all candidates underwent bariatric surgery. Pregnancy rates for women seeking fertility were 95.2% for PCOS and 76.9% for controls and live birth rates were 81.0% and 69.2%, respectively. After surgery, the time to achieve the first pregnancy was 34 ± 28 months in women with PCOS and 32 ± 25 months in controls. Pregnancy and fertility rates were high in very obese women with PCOS after bariatric surgery, with few maternal and neonatal complications.
