Meta Analysis
Impact of Bariatric Surgery on Male Sex Hormones and Sperm Quality: a Systematic Review and Meta-Analysis.
This systematic review and meta-analysis aims to establish the effects of bariatric surgery on male sex hormones, sperm parameters, and sexual function. We searched MEDLINE, EMBASE, Web of Science, and Scopus from database inception through June 2018. Articles were eligible for inclusion if they examined the effect of bariatric surgery on male sex hormones and sperm parameters in patients with obesity. ⋯ However, bariatric surgery did not affect sperm quality, DHEA, androstenedione, and inhibin B levels. Sustained weight-loss induced by bariatric surgery had a significant effect on increasing male sex hormones and decreasing female sex hormones in male patients with obesity. However, sperm quality and function were not improved after surgery.

Durability is a key requirement for the broad acceptance of bariatric surgery. We report on durability at and beyond 10 years with a systematic review and meta-analysis of all reports providing data at 10 or more years and a single-centre study of laparoscopic adjustable gastric banding (LAGB) with 20 years of follow-up. ⋯ All current procedures are associated with substantial and durable weight loss. More long-term data are needed for one-anastomosis gastric bypass and sleeve gastrectomy. Reoperation is likely to remain common across all procedures.
