More than a third of young military personnel report experiencing some level of erectile dysfunction (ED). Preoccupation with body image, particularly genitals, is a distraction that can influence sexual anxiety (SA) and sexual functioning problems (SFPs), particularly ED.
This study assessed the relationships between male genital self-image (MGSI), SA, and ED in a sample of male military personnel age 40 or younger.
Data were from a larger study on SFPs in military populations. This sample consisted of 367 male military personnel age 40 or younger. Hierarchical regression analyses and process modeling using mediation analysis were performed to examine the effects of MGSI on ED with SA as an intermediate variable. We predicted that SA would mediate the relationship between MGSI and ED.
ED severity was assessed with the International Index of Erectile Function. MGSI was assessed using the MGSI Scale. SA was assessed with the SA subscale of the Sexual Needs Scale.
As hypothesized, greater satisfaction with MGSI was predictive of significantly lower SA (F[8, 352] = 4.07, P = 0.001) and lower ED (F[8, 352] = 13.20, P = 0.001). Lower levels of SA were predictive of lower levels of ED (F[8, 354] = 21.35, P < 0.001). Additionally, results also revealed a significant indirect effect of MGSI on ED through SA (b = -0.07, standard error = 0.03, confidence interval = [-0.14,-0.02], P < 0.05), indicating mediation of MGSI on ED via SA.
This study underscores the complex etiologic basis of SFPs, particularly ED, and highlights the importance of considering psychologic contributors to ED, such as SA and MGSI. Strategies aimed at reducing SA may be useful in improving ED in young military populations and are worth considering as complements to strategies that improve SFPs.
超过三分之一的年轻军事人员报告称经历过某种程度的勃起功能障碍（ED）。过度关注身体形象，尤其是生殖器，是一种会影响性焦虑（SA）和性功能问题（SFP），特别是勃起功能障碍的干扰因素。
本研究评估了40岁及以下男性军事人员样本中男性生殖器自我形象（MGSI）、性焦虑和勃起功能障碍之间的关系。
数据来自一项关于军事人群性功能问题的更大规模研究。该样本由367名40岁及以下的男性军事人员组成。进行了分层回归分析和使用中介分析的过程建模，以检验以性焦虑作为中间变量时，男性生殖器自我形象对勃起功能障碍的影响。我们预测性焦虑将介导男性生殖器自我形象与勃起功能障碍之间的关系。
使用国际勃起功能指数评估勃起功能障碍的严重程度。使用男性生殖器自我形象量表评估男性生殖器自我形象。使用性需求量表的性焦虑子量表评估性焦虑。
如假设的那样，对男性生殖器自我形象的更高满意度预示着性焦虑显著降低（F[8, 352] = 4.07，P = 0.001）和勃起功能障碍程度降低（F[8, 352] = 13.20，P = 0.001）。较低水平的性焦虑预示着较低水平的勃起功能障碍（F[8, 354] = 21.35，P < 0.001）。此外，结果还显示男性生殖器自我形象通过性焦虑对勃起功能障碍有显著的间接影响（b = -0.07，标准误差 = 0.03，置信区间 = [-0.14, -0.02]，P < 0.05），表明男性生殖器自我形象通过性焦虑介导对勃起功能障碍的影响。
本研究强调了性功能问题，特别是勃起功能障碍复杂的病因基础，并突出了考虑性焦虑和男性生殖器自我形象等心理因素对勃起功能障碍影响的重要性。旨在减少性焦虑的策略可能有助于改善年轻军事人群的勃起功能障碍，值得作为改善性功能问题策略的补充加以考虑。
