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

Beneficial effects of trehalose and gentiobiose on human sperm cryopreservation

The protection of human sperm during cryopreservation is of great importance to infertility. Recent studies have shown that this area is still a long way from its ultimate aim of maintaining the maximum viability of sperm in cryopreservation. The present study used trehalose and gentiobiose to prepare the human sperm freezing medium during the freezing-thawing. The freezing medium of sperm was prepared with these sugars, and the sperm were then cryopreserved. The viable cells, sperm motility parameters, sperm morphology, membrane integrity, apoptosis, acrosome integrity, DNA fragmentation, mitochondrial membrane potential, reactive oxygen radicals, and malondialdehyde concentration was evaluated using standard protocols. A higher percentage of the total and progressive motility, rate of viable sperm, cell membrane integrity, DNA and acrosome integrity, and mitochondrial membrane potential were observed in the two frozen treatment groups compared to the frozen control. The cells had less abnormal morphology due to treatment with the new freezing medium than the frozen control. The higher malondialdehyde and DNA fragmentation were significantly observed in the two frozen treatment groups than in the frozen control. According to the results of this study, the use of trehalose and gentiobiose in the sperm freezing medium is a suitable strategy for sperm freezing to improve its motion and cellular parameters.

Male Sexual Health Related Complications Among Combat Veterans

INTRODUCTION

With improved armor and combat trauma care, more male service members in the 21st century are surviving devastating injuries to their genitourinary (GU) system. The impact of these injuries can have long lasting effect on their sexual function and fertility status.

OBJECTIVES

To review the current literature on sexual health-related complications and fertility implications among male service members sustaining combat related injuries.

METHODS

We performed a literature search that included male sexual health complications and combat injuries using PubMed and Google Scholar. We reviewed the impact of traumatic injuries to the pelvis and perineum on sexual function and fertility, and we also discuss sexual dysfunction from posttraumatic stress disorder (PTSD) and traumatic brain injuries (TBI).

RESULTS

Injuries sustained during combat are usually polytraumatic, especially in recent conflicts with improvised explosive devices. The majority of GU combat injuries involve the scrotum, testes, and penis resulting in lasting structural dysfunction. PTSD is associated with higher levels of erectile dysfunction, hypoactive sexual desire, and premature ejaculation. Overall, veterans diagnosed with PTSD had a higher risk of developing sexual dysfunction. Veterans with TBI experience sexual health complications, such as decreased libido, difficulties with arousal maintenance, and the ability to achieve orgasm. Combat related injuries can have significant fertility implications on service members as they typically serve in their peak fertility years.

CONCLUSIONS

Traumatic GU injuries, PTSD, TBI, and associated endocrine dysfunction can all contribute to sexual dysfunction among combat veterans. Given the complex nature of sexual dysfunction in this population, these patients are best managed by a multidisciplinary team. Castillo O, Chen IK, Amini E, et al.

Social sperm freezing

Increased paternal age has been associated with lower fertility and higher genetic risk for the offspring. One way to prevent these consequences is to freeze sperm at a young age. Social sperm freezing could be developed in a way similar to social oocyte freezing. The main difference between freezing oocytes and sperm is that social sperm freezing is much less focussed on fertility preservation and much more on avoiding increased genetic risk. Contrary to what some people seem to believe, sperm freezing is more complicated than it looks at first sight. This article considers three practical aspects: freezing, storage and testing. It is concluded that the remedy (cryopreservation) may itself cause damage to the quality of the spermatozoon and to its genetic integrity, thus undoing the possible benefits in terms of fertility and health of offspring.

And When I Die: Theory of Planned Behavior as Applied to Sperm Cryopreservation

The present study investigates fertility intentions of men, aged 18-59, as expressed in willingness to cryopreserve sperm for future use in procreation. An economic stated-preference framework is combined with the Theory of Planned Behavior (TPB) to investigate which attributes are important in the decision to cryopreserve sperm, what is the Willingness to Pay (WTP) for cryopreservation, and which attributes influence it. A structured, two-part questionnaire was used, based on WTP and Conjoint analysis (CA) applied in tandem to elicit respondents' preferences in evaluating utility. Findings show which attributes are important in the decision to cryopreserve sperm among them Risk of Infertility, Personal monthly income, Chance of pregnancy from frozen semen, Age and what are significant predictor variables for the WTP which are Personal monthly income, Importance of the risk of infertility, Initial registration fee to sperm bank and cryopreservation, and Degree of religious observance. The findings further demonstrate that respondents value sperm cryopreservation and have a positive WTP for it as it seems to contribute to improving well-being. As a result of these findings, governments should consider state funding for cryopreservation as part of national health policy.
