Effects of bariatric surgery on sexual function and fertility: A narrative review.

Summary: Obesity has emerged as a prevalent global health concern, with its detrimental effects on the reproductive system and sexual function garnering increasing attention. Both men and women affected by obesity face a heightened risk of fertility challenges and sexual dysfunction. Although fertility and sexual function are distinct topics, they are intricately linked and mutually influential in both medical and societal contexts. Bariatric surgery (BS) has generated promising results in alleviating sexual dysfunction and enhancing fertility, results which are often gender specific. In men, improvements in sexual function can often be attributed to weight loss and subsequent optimizations in sex hormone levels. However, improving female sexual function may be related to a range of factors beyond weight loss. Bariatric procedures have shown limited benefits for male fertility; in fact, in some situations it can even be detrimental, leading to a decrease in sperm count and quality. Conversely, BS may positively impact female fertility, improving pregnancy and neonatal outcomes. Nevertheless, it is essential to consider the potential risks related to the adverse effects of malnutrition and rapid weight loss following BS, making it advisable to wait for 12–18 months before attempting pregnancy.
