Owing to increasing access to Web-based pornography and concerns about its impact on viewers, many researchers have attempted to systematically analyze the content of pornography.
We aimed to systematically review the results of quantitative content analyses of video-based pornography and identify the degree to which the following behaviors are depicted: (1) sexual behaviors and themes, (2) condom use during sexual behaviors, and (3) aggression and violence.
Inclusion criteria for article eligibility were (1) peer-reviewed publications, (2) articles in the English language, (3) articles describing a quantitative content analysis of video pornography, and (4) articles quantitatively examining at least one variable of interest.
A total of 23 studies met the eligibility criteria. Studies varied in scope and definitions of behavioral variables. Condom use was rare, although more commonly depicted in gay male pornography (36%-64% videos) compared with heterosexual pornography (2%-3% videos). Normative sexual behaviors were most frequently depicted in pornography samples (eg, vaginal intercourse in 48%-90% and fellatio in 52%-90% of heterosexual videos; fellatio in 66%-100% and anal intercourse in 70%-80% of gay male videos). Extreme acts of violence (1%-3% videos) and rape (0%-6% videos) were relatively rare. However, more subtle forms of aggression, such as spanking (5%-75% videos), were more common, and unequal sexual relations (eg, domination) were also common. Although estimates varied by study, dominating and violent behaviors were nearly always directed toward women.
Condom nonuse and gender inequalities are common in pornography, which has implications for the development of healthy sexual relationships among pornography viewers. Higher quality research, including study replication and consistent methodological choices, is needed.
由于人们越来越容易接触到网络色情内容，且担心其对观看者的影响，许多研究人员试图对色情内容进行系统分析。
我们旨在系统回顾基于视频的色情内容定量分析结果，并确定以下行为的呈现程度：（1）性行为及主题；（2）性行为中避孕套的使用情况；（3）攻击和暴力行为。
文章纳入标准为：（1）经过同行评审的出版物；（2）英文文章；（3）描述视频色情内容定量分析的文章；（4）对至少一个感兴趣变量进行定量研究的文章。
共有23项研究符合纳入标准。各项研究在行为变量的范围和定义上存在差异。避孕套的使用情况很少见，不过在男同性恋色情作品中（36%-64%的视频）比在异性恋色情作品中（2%-3%的视频）更常出现。规范性性行为在色情样本中最为常见（例如，异性恋视频中48%-90%出现阴道性交，52%-90%出现口交；男同性恋视频中66%-100%出现口交，70%-80%出现肛交）。极端暴力行为（1%-3%的视频）和强奸行为（0%-6%的视频）相对较少。然而，更微妙的攻击形式，如打屁股（5%-75%的视频）更为常见，不平等的性关系（如支配）也很常见。尽管不同研究的估计有所不同，但支配和暴力行为几乎总是针对女性。
色情作品中不使用避孕套和性别不平等现象普遍，这对色情作品观看者健康的性关系发展具有影响。需要开展更高质量的研究，包括重复研究和一致的方法选择。
