Marijuana use is increasingly prevalent in the United States. Effects of marijuana use on sexual function are unclear, with contradictory reports of enhancement and detriment existing.
To elucidate whether a relation between marijuana use and sexual frequency exists using a nationally representative sample of reproductive-age men and women.
We analyzed data from cycle 6 (2002), cycle 7 (2006-2010), and continuous survey (2011-2015) administrations of the National Survey of Family Growth, a nationally representative cross-sectional survey. We used a multivariable model, controlling for demographic, socioeconomic, and anthropographic characteristics, to evaluate whether a relationship between marijuana use and sexual frequency exists.
Sexual frequency within the 4 weeks preceding survey administration related to marijuana use and frequency in the year preceding survey administration.
The results of 28,176 women (average age = 29.9 years) and 22,943 men (average age = 29.5) were analyzed. More than 60% of men and women were Caucasian, and 76.1% of men and 80.4% of women reported at least a high school education. After adjustment, female monthly (incidence rate ratio [IRR] = 1.34, 95% CI = 1.07-1.68, P = .012), weekly (IRR = 1.36, 95% CI = 1.15-1.60, P < .001), and daily (IRR = 1.16, 95% CI = 1.01-1.32, P = .035) marijuana users had significantly higher sexual frequency compared with never users. Male weekly (IRR = 1.22, 95% CI = 1.06-1.41, P = .006) and daily (IRR = 1.36, 95% CI = 1.21-1.53, P < .001) users had significantly higher sexual frequency compared with never users. An overall trend for men (IRR = 1.08, 95% CI = 1.05-1.11, P < .001) and women (IRR = 1.07, 95% CI = 1.04-1.10, P < .001) was identified showing that higher marijuana use was associated with increased coital frequency.
Marijuana use is independently associated with increased sexual frequency and does not appear to impair sexual function.
Our study used a large well-controlled cohort and clearly defined end points to describe a novel association between marijuana use and sexual frequency. However, survey responses were self-reported and represent participants only at a specific point in time. Participants who did not answer questions related to marijuana use and sexual frequency were excluded.
A positive association between marijuana use and sexual frequency is seen in men and women across all demographic groups. Although reassuring, the effects of marijuana use on sexual function warrant further study. Sun AJ, Eisenberg ML.

在美国，大麻的使用越来越普遍。大麻使用对性功能的影响尚不清楚，现有的报告既有增强作用也有损害作用。
使用具有代表性的育龄期男性和女性人群的全国性样本，阐明大麻使用与性频率之间是否存在关系。
我们分析了全国生育调查循环 6 期（2002 年）、循环 7 期（2006-2010 年）和连续调查（2011-2015 年）的数据，全国生育调查是一项具有代表性的横断面调查。我们使用多变量模型，控制人口统计学、社会经济和人体测量特征，评估大麻使用与性频率之间的关系。
在调查前 4 周内与大麻使用和前一年调查前的频率相关的性频率。
分析了 28176 名女性（平均年龄 29.9 岁）和 22943 名男性（平均年龄 29.5 岁）的结果。超过 60%的男性和女性是白种人，76.1%的男性和 80.4%的女性报告至少接受过高中教育。调整后，女性每月（发病率比 [IRR] = 1.34，95%CI = 1.07-1.68，P =.012）、每周（IRR = 1.36，95%CI = 1.15-1.60，P <.001）和每日（IRR = 1.16，95%CI = 1.01-1.32，P =.035）大麻使用者的性频率明显高于非使用者。男性每周（IRR = 1.22，95%CI = 1.06-1.41，P =.006）和每日（IRR = 1.36，95%CI = 1.21-1.53，P <.001）使用者的性频率明显高于非使用者。男性（IRR = 1.08，95%CI = 1.05-1.11，P <.001）和女性（IRR = 1.07，95%CI = 1.04-1.10，P <.001）均呈现出总体趋势，表明大麻使用量越高，性行为频率越高。
大麻的使用与性频率的增加独立相关，似乎不会损害性功能。
我们的研究使用了一个大型的、控制良好的队列，并使用明确界定的终点来描述大麻使用和性频率之间的新关联。然而，调查答复是自我报告的，仅代表特定时间点的参与者。未回答大麻使用和性频率相关问题的参与者被排除在外。
在所有人群中，大麻使用与男性和女性的性频率之间都存在正相关。尽管令人放心，但大麻对性功能的影响仍需要进一步研究。
