: This study aimed to assess the penile circumference in its flaccid and erect states using a Rigiscan monitoring device and Audiovisual Sexual Stimulation (AVSS) within a large Chinese male cohort to establish an objective standard. : 1,134 men participated between January 2019 and June 2021. 803 men, achieving a hardness of 80% or more, were included. Circumferences of the penis' base and tip in its flaccid and erect states were documented, and averages were compared across age groups and Chinese regions. Age-related correlations were explored. : Flaccid penile base and tip averaged 7.25 ± 0.60 cm and 7.20 ± 0.71 cm. At 80% erection, they were 9.70 ± 0.65 cm and 9.65 ± 0.75 cm. The increase in circumference from flaccid to 80% erect for the base and tip was approximately 25.31% and 25.47%, respectively. Correlations between flaccid and erect states were significant (tip: = 0.807, base: = 0.828, both < 0.01). No significant age or regional variations in penile circumference were found. : Our data on 803 subjects measured with Rigiscan showed that penile circumferences in flaccid and erect states show a strong correlation, in Chinese population. Penile size does not seem significantly influenced by age or region.
这项研究旨在使用 Rigiscan 监测设备和视听性刺激（AVSS）评估中国男性群体中阴茎在疲软和勃起状态下的周长，以建立客观标准。 1134 名男性参与了 2019 年 1 月至 2021 年 6 月的研究。纳入了 803 名硬度达到 80%或以上的男性。记录了阴茎疲软和勃起状态下根部和尖端的周长，并比较了不同年龄组和中国地区的平均值。探讨了与年龄相关的相关性。 阴茎疲软根部和尖端的平均周长分别为 7.25±0.60cm 和 7.20±0.71cm。在 80%勃起时，它们分别为 9.70±0.65cm 和 9.65±0.75cm。从疲软到 80%勃起时，根部和尖端的周长分别增加了约 25.31%和 25.47%。疲软和勃起状态之间的周长相关性具有统计学意义（尖端： = 0.807，根部： = 0.828，均<0.01）。未发现阴茎周长在年龄或地区方面存在显著差异。 我们使用 Rigiscan 对 803 名受试者进行的研究表明，中国男性群体中，疲软和勃起状态下的阴茎周长具有很强的相关性。阴茎大小似乎不受年龄或地区的显著影响。
