This study aimed to determine the normal size of the male external genital organs and anogenital distance in human fetuses during the fetal period through the anatomic morphometric method. The study was performed on 104 spontaneously aborted human male fetuses aged between 10 and 39 weeks of gestation. Fetuses were divided into groups according to gestational weeks, months, and trimesters. Parameters belonging to the male external genital organs were measured, including penile length and width, transverse scrotal diameter, anterior-posterior scrotal diameter, the distance from the anterior and posterior aspect of the penis to the center of the anus, and the anogenital distance. The mean of each parameter was computed by gestational weeks, months, and trimester groups, and data were presented as mean ± standard deviation. The mean of each parameter increased with gestational age, and statistically significant differences were observed between trimester groups. A high correlation was also determined between gestational age and the parameters measured.
本研究旨在通过解剖形态测量法确定胎儿期人类男性胎儿外生殖器器官的正常大小及肛门生殖距离。研究选取了104例妊娠10至39周自然流产的人类男性胎儿。根据孕周、月份和孕期将胎儿分组。测量了属于男性外生殖器器官的参数，包括阴茎长度和宽度、阴囊横径、阴囊前后径、阴茎前后端至肛门中心的距离以及肛门生殖距离。通过孕周、月份和孕期组计算每个参数的平均值，并以平均值±标准差表示数据。每个参数的平均值随孕周增加，且在孕期组之间观察到统计学上的显著差异。还确定了孕周与所测参数之间存在高度相关性。
