To compare the morphology of the hymen in adolescent girls who have and have not had sexual intercourse involving penile-vaginal penetration.
Female patients aged 13 to 19 years, recruited from an urban adolescent medicine practice.
Subjects were interviewed in private after completing detailed questionnaires and then underwent a physical examination. External genital inspections were performed using a colposcope with an attached 35-mm camera to document the appearance of the hymen. The presence of notches or clefts was recorded during the examination, and photographs taken at x10 magnification were used to take measurements of the width of the posterior hymenal rim.
Posterior hymenal notches and clefts were more common among girls admitting past intercourse (13/27 [48%]) than in girls who denied intercourse (2/58 [3%]; P =.001), but the mean width of the posterior hymenal rim was not significantly different between the 2 groups (2.5 mm vs 3.0 mm; P =.11). Two subjects who denied intercourse but had posterior hymenal clefts described a painful first experience with tampon insertion.
Deep notches or complete clefts in the posterior rim of the hymen were rare in girls who denied intercourse. Subjects who admitted past intercourse still had nondisrupted, intact hymens in 52% of cases.
比较有和没有经历过阴茎-阴道插入式性交的青春期女孩处女膜的形态。
从城市青少年医学诊所招募的13至19岁女性患者。
在完成详细问卷后对受试者进行单独访谈，然后进行体格检查。使用配有35毫米相机的阴道镜进行外阴检查，以记录处女膜的外观。检查过程中记录有无切迹或裂伤，并使用10倍放大拍摄的照片测量处女膜后缘的宽度。
承认有过性交的女孩中，处女膜后切迹和裂伤比否认有过性交的女孩更常见（13/27 [48%] 对比2/58 [3%]；P = 0.001），但两组处女膜后缘的平均宽度无显著差异（2.5毫米对比3.0毫米；P = 0.11）。两名否认有过性交但有处女膜后裂伤的受试者描述了首次使用卫生棉条时的疼痛经历。
否认有过性交的女孩中，处女膜后缘的深切迹或完全裂伤很少见。承认有过性交的受试者中，52% 的病例处女膜仍未破裂、完整。
