Long-term effect of sleeve gastrectomy surgery on Hormonal Profile, Semen Parameters and sexual functions of obese infertile men; a prospective observational study

BACKGROUND

The effect of bariatric surgery on impaired semen parameters, hormonal profile and sexual function remains controversial to some extent.

THE CONTEXT AND PURPOSE OF THE STUDY

To look at the long-term effects of sleeve gastrectomy on hormonal profiles, sperm parameters, and sexual function in infertile men with severe obesity. This prospective study included fifty-four obese patients with primary or secondary infertility who were scheduled for sleeve gastrectomy between February 2018 and March 2021. All participants were given a sperm analysis and a serum hormone profile before, 12, and 18 months after surgery. We used the International Index of Erectile Function questionnaire to assess sexual function.

RESULTS

There was a significant correlation between weight loss after sleeve gastrectomy and improvement in lipid profile (p < 0.05). No significant detectable effect of post-gastrectomy weight loss on patients with diabetes mellitus, hypertension, or obstructive sleep apnea. As regards the hormonal profile, sex hormone binding globulin, total and free testosterone improved significantly after 12- and 18-months following sleeve gastrectomy. There was a significant increase in sperm count and total sperm number during the follow-up after sleeve gastrectomy (p < 0.05), however, there were no significant changes in other semen parameters. Concerning sexual function, sexual desire, erectile function, and satisfaction improved significantly at 12 and 18 months after surgery.

CONCLUSION

Weight loss through sleeve gastrectomy surgery significantly improves testosterone deficiency, sexual performance, and Sperm count in obese infertile men.

Randomized comparison of effect of standard antibiotic prophylaxis versus enhanced prophylactic measures on rate of urinary tract infection after flexible ureteroscopy

PURPOSE

To compare the rate of post-flexible ureteroscopy urinary tract infection (UTI) in patients subjected to the standard antibiotic prophylaxis alone versus enhanced prophylactic measures.

METHODS

A prospective randomized controlled study included 256 patients subjected to flexible ureteroscopy (FURS) for ureteral or renal stones from March 2018 to July 2022. Treatment groups included the standard antibiotic prophylaxis group (group 1, n=128) and the enhanced prophylaxis group (group 2, n=128). Patients in group 1 were injected with intravenous fluoroquinolone one hour preoperatively, and oral antibiotics were used for 24 h postoperatively. Patients in group 2 had urine culture ten days before the procedure; antibiotic-culture based was given for positive asymptomatic cases, while the procedure was deferred for active UTI.

RESULTS

The study groups were comparable regarding patient demographics, stone characteristics, operative time, and intraoperative complications. The overall hospitalization time was 1.68 ± 0.81 days. Postoperative, and overall complications were significantly higher in group 1 (15.6% vs. 6.3%, p = 0.04 and 26.6% vs. 17.2%, p = 0.047), respectively. Twenty patients (15.6 %) in the standard prophylaxis group were diagnosed with UTI in comparison to 8 patients (6.3 %) in the enhanced prophylaxis group (p = 0.047).

CONCLUSIONS

Urinary tract infection after FURS could be reduced significantly by utilizing the suggested enhanced prophylactic approach.
