The role of oral antioxidants in the improvement of sperm parameters in infertile men.

PURPOSE: A variety of pathologic conditions may increase oxidative stress in semen resulting in structural modifications to spermozoa's plasma membrane that interfere with sperm motility, morphology, and count. Antioxidants are currently being marketed to treat male infertility. In semen, antioxidants may decrease oxidative stress and potentially improve sperm parameters. In this narrative, mini-review we evaluated the effectiveness of antioxidants in infertility. METHODS: This mini-review of the current literature has been carried out through searching of the PubMed and Google scholar databases. RESULTS AND CONCLUSIONS: The literature review suggests that there is evidence that oral antioxidants such as selenium, carnitine, zinc, coenzymeQ10, vitamins E and C, etc. alone or in combinations, improve sperm count, motility, morphology as well as pregnancy rates in infertile men with idiopathic oligoasthenospermia. Unfortunately, most of these studies are poorly designed, limited by sample size, varying in dosage, differing in primary end points, and most notably lacking live birth data. Importantly, large randomized, well-designed, placebo-controlled trials are needed.

Management of Fournier's Gangrene in a COVID-19 Patient: Challenges and Dilemmas.

Fournier's gangrene is a urologic emergency manifested as an aggressive form of necrotizing fasciitis. Co-infection of Fournier's gangrene with COVID-19 might have catastrophic sequelae. We report a case of a 69-year-old male patient, unvaccinated against coronavirus, was obese, and with type 2 diabetes diagnosed with Fournier's gangrene. Apart from administration of piperacillin/tazobactam and clindamycin, the patient underwent surgical debridement four hours after his presentation. Postoperatively, the PCR test for COVID-19 was proved to be positive. The patients develop septic shock necessitating the delivery of dopamine, supplemental oxygen, and thromboprophylaxis. On the seventh postoperative day, left testicular ischemia was developed and ipsilateral orchiectomy was performed. After his full recovery from an in-hospital infection by Acinetobacter baumannii, the patient was transferred to the plastic surgery department. The prompt surgical debridement has likely counterbalanced the health risk originated from COVID-19 infection, contributing to the patient's full recovery. Testicular ischemia is a very rare condition in necrotizing fasciitis of the genital and perineal space and it could be attributed primarily to the thrombotic nature of coronavirus. Due to the assault of multiple organs and systems, a medical board consisting of urologists and other medical specialties substantially contributed to the favorable outcome.
