An understanding of ranges in clitoral anatomy is important for clinicians caring for patients including those who have had female genital mutilation, women seeking genital cosmetic surgery, or trans women seeking reconstructive surgery. The aim of this meta-analysis is to investigate the ranges in clitoral measurements within the literature. A meta-analysis was performed on Ovid Medline and Embase databases following the PRISMA protocol. Measurements of clitoral structures from magnetic imaging resonance, ultrasound, cadaveric, and living women were extracted and analyzed. Twenty-one studies met the inclusion criteria. The range in addition to the average length and width of the glans (6.40 mm; 5.14 mm), body (25.46 mm; 9.00 mm), crura (52.41 mm; 8.71 mm), bulb (52.00 mm; 10.33 mm), and prepuce (23.19 mm) was calculated. Furthermore, the range and average distance from the clitoris to the external urethral meatus (22.27 mm), vagina (43.14 mm), and anus (76.30 mm) was documented. All erectile and non-erectile structures of the clitoris present with substantial range. It is imperative to expand the literature on clitoral measurements and disseminate the new results to healthcare professionals and the public to reduce the sense of inadequacy and the chances of iatrogenic damage during surgery.
了解阴蒂解剖结构的范围对于照顾患者的临床医生很重要，这些患者包括接受过女性生殖器切割的人、寻求生殖器整容手术的女性或寻求重建手术的跨性别女性。本荟萃分析的目的是研究文献中阴蒂测量值的范围。按照PRISMA方案对Ovid Medline和Embase数据库进行了荟萃分析。提取并分析了来自磁共振成像、超声、尸体和活体女性的阴蒂结构测量值。21项研究符合纳入标准。计算了除阴蒂头的平均长度和宽度（6.40毫米；5.14毫米）、体部（25.46毫米；9.00毫米）、脚（52.41毫米；8.71毫米）、球部（52.00毫米；10.33毫米）和包皮（23.19毫米）之外的范围。此外，记录了阴蒂到尿道外口（22.27毫米）、阴道（43.14毫米）和肛门（76.30毫米）的范围和平均距离。阴蒂的所有勃起和非勃起结构都存在很大的范围差异。必须扩充关于阴蒂测量的文献，并将新结果传播给医疗保健专业人员和公众，以减少手术期间的不足感和医源性损伤的可能性。
