Military Genitourinary Trauma:Policies, Implications, and Ethics

Fertility Preservation Before Deployment: Oocyte and Sperm Freezing in Members of the Active Duty Military

Active duty military service and deployment has the potential to compromise fertility through combat-related genitourinary injury, gonadotoxic exposures, and physical separation from a partner. Despite a growing interest among the military community as well as promising efficacy and safety data, fertility preservation remains an uncovered benefit for active duty soldiers. In 2016, the Pentagon proposed a program that would cover oocyte and sperm cryopreservation for any member of the active duty military desiring its use. Regrettably, that funding was not secured and predeployment fertility preservation remains an out-of-pocket expense. Today, advocacy groups, non-for-profit organizations, and physicians remain vigilant in their attempts to drive another government initiative through Congress. While activism continues, it is important to stress the value of fertility preservation counseling in soldiers' predeployment preparation and military family planning.

The efficacy of antioxidants in sperm parameters and production of reactive oxygen species levels during the freeze-thaw process: A systematic review and meta-analysis

To investigate the impact of antioxidants in sperm parameters and reduction in reactive oxygen species production during the freeze-thaw process. PubMed, Scopus, Web of Science, Embase and Cochrane central library were systematically searched. Of the 1583 articles, 23 studies were selected for data extraction. Our results show that antioxidants improved sperm progressive motility (standardised mean difference (SMD) = 1; 95% CI: 0.62, 1.38; p < .001) and viability (SMD = 1.20; 95% CI: 0.50, 1.91; p = .001) and reduced sperm DNA fragmentation (SDF) and hydrogen peroxide (H₂ O₂ ) production, but there was no significant improvement in total sperm motility after thawing. Acetyl-l-carnitine/l-carnitine, melatonin and catalase had a significant positive impact on progressive motility. The role of tempol and melatonin in improving viability was significant compared to other antioxidants. Moreover, a significant reduction in SDF was observed after addition of butylated hydroxytoluene, tempol and vitamin E. However, the prevention of H₂ O₂ production was significant only after the addition of tempol. Our overall results displayed the positive impact of antioxidants on progressive sperm motility, viability and reduction in SDF and H₂ O₂ production, but no significant impact of antioxidants on total sperm motility was seen during the freeze-thaw process.
